(Universidade Federal do Pará, 2024-08-09) MORAES, Janine Brasil de Araújo; NEVES, Laura Maria Tomazi; http://lattes.cnpq.br/4235603520707156; HTTPS://ORCID.ORG/0000-0002-3115-2571; CARNEIRO, Saul Rassy Carneiro; http://lattes.cnpq.br/9162153771863939; https://orcid.org/0000-0002-6825-0239
Introduction: Introduction: Ageing can be accompanied by a progressive decline in muscle mass, strength and function. This resulting health condition is known as sarcopenia, a muscle disease that develops progressively and chronically. Age-related sarcopenia has several factors that accelerate this process and need to be identified and controlled in order to promote a good health prognosis and quality of life for the elderly population. Objective: To assess the association between sarcopenia and functional and quality of life indicators in elderly people treated at the geriatrics outpatient clinic of the João de Barros Barreto University Hospital (HUJBB). Methods: This is an observational, analytical, cross-sectional study carried out at the HUJBB geriatrics outpatient clinic. Sociodemographic and clinical assessments were carried out: sarcopenia assessment (SARC-Calf, handgrip strength assessment, Tetrapolar Electrical Bioimpedance (BIA) and Short Physical Performance Battery (SPPB)), functional indicators assessment (Barthel, quadriceps strength assessment, physical activity level assessment (IPAQ) and presence of falls in 60 days) and quality of life assessment (SF-12). The algorithm of the European Working Group on sarcopenia in the elderly (EWGSOP2) was used. Results: 129 participants were assessed (73% women, p = 0.001), with a mean age of 75.4 years and from the capital (80.6%). 57% were found to be at risk of sarcopenia, with a prevalence of sarcopenia of 27.1%. Handgrip strength (HGS) 18kg/f, skeletal muscle mass 18.3kg; SPPB 9 points; Barthel score 58.8% of independent participants; quadriceps strength 14kg/f; IPAQ 38.8% with a low level of physical activity and SF-12 37.7 points for the physical component and 48.2 points for the mental component. There was an association between appendicular skeletal muscle mass (ASMR) and calf circumference (WC), age, SARC-Calf, FPM and quality of life (physical component) for men (adjusted R2 0.42 and p<0.05), as well as sarcopenia, classified by ASMR, with BIA variables: body resistance, total body water in lean mass, lean mass and basal metabolic rate for men (adjusted R2 0.49 and p<0.05), and for women, intracellular water and total body water in body weight (adjusted R2 0.60 and p<0.05). Conclusion: This study concludes that WC, age, sarcopenia risk screening, HGS and quality of life were associated with MMEA measured by BIA. For the diagnosis of sarcopenia, there were different associations between the BIA markers when adjusted for gender.

(Universidade Federal do Pará, 2024-04-24) SANTOS, Mayara do Socorro Brito dos; TORRES, Natáli Valim Oliver Bento; http://lattes.cnpq.br/1927198788019996; https://orcid.org/0000-0003-0978-211X
Introduction: Instruments with appropriate psychometric properties are essential for ensuring the quality of assessments and reassessments in clinical practice, guiding decision-making regarding rehabilitation procedures. The Pittsburgh Fatigability Scale, originally published in English, is the only validated scale for measuring perceived fatigability in older adults. Considering the importance of this tool, it is necessary to validate its translated version into Portuguese and adapt it to the specificities of the Brazilian context. Objective: To validate the Pittsburgh Fatigability Scale Brazilian Portuguese version (PFS-Brasil) by evaluating its validity in relation to measures of physical activity, physical performance, and cognitive performance. Methodology: The scale and physical and cognitive performance tests were used to assess 121 healthy older adults residing in the community. We conducted statistical analyses of the physical and mental subscales of the PFS-Brasil, utilizing the intraclass correlation coefficient (ICC) for reliability analysis, Cronbach's alpha for internal consistency evaluation, and Spearman's correlation for convergent validity. Furthermore, we examined agreement analysis and floor and ceiling effects. The Statistical Package for Social Sciences 25.0 was used for data analysis. Results: The analyses indicated that the physical and mental subscales exhibit satisfactory test-retest reliability, with ICC values for the physical subscale (0.84; 95% CI: 0.80-0.88) and the mental subscale (0.83; 95% CI: 0.78-0.87), in addition to high internal consistency (α = 0.84 and 0.82, respectively). These values are indicative of good inter-rater reliability, revealing a low probability of random and systematic error. Bland-Altman plots demonstrated good agreement for both subscales of the PFS-Brasil. For convergent validity, the higher physical score showed a moderate association, and the higher mental score showed a weak association with lower physical performance (6-minute walk tests and the Short Physical Performance Battery (SPPB) and lower levels of physical activity (International Physical Activity Questionnaire – IPAQ). Regarding cognitive performance, there was a weak association between the higher mental score and the average accuracy on the flanker test. No ceiling effects were observed in both subscales; however, the mental subscale exhibited a floor effect (n = 24%). Conclusion: This study demonstrated that the Brazilian version of the Pittsburgh Fatigability Scale is a valid, consistent, and reliable instrument for assessing perceived fatigability in older adults.

Associação de obesidade sarcopênica, indicadores de composição corporal, de variabilidade da frequência cardíaca e de esforço no teste do degrau de seis minutos com a severidade da Síndrome da Apneia Obstrutiva do Sono: Um estudo transversal
(Universidade Federal do Pará, 2025-12-19) SOUZA, Leornado Brynne Ramos de; CRISP, Alex Harley; http://lattes.cnpq.br/1187580727139009; HTTPS://ORCID.ORG/0000-0003-4683-9576; NEVES, Laura Maria Tomazi; http://lattes.cnpq.br/4235603520707156; https://orcid.org/0000-0002-3115-2571
Introduction: Obstructive sleep apnea syndrome (OSAS) is the most common sleep- related respiratory disorder in the world, with different levels of severity. The literature indicates that increased body fat can increase energy expenditure, alter heart rate variability during sleep and wakefulness and affects the severity of the syndrome. Thus, there is a greater risk of muscle catabolism, negatively influencing cellular health, measured by the phase angle in bioelectrical impedance. However, few studies have expanded the assessment of body composition in relation to sarcopenic obesity in this population. In addition, the results of current research are also conflicting when analyzing the impacts of OSAS severity on metabolic and physical performance during stress tests. Objective: To investigate the association of indicators of body composition, heart rate variability, and stress in the six-minute step test with the severity of OSAS. Methods: Cross-sectional, quantitative study that took place between December 2023 and August 2024, with a single sample of 37 people diagnosed with OSAS, age 53,7 ± 13,8 years, minimum age 28 years and maximum age 78 years, confirmed by type 1 polysomnography. Data collection was performed in two phases: a) Rest, using bioelectrical impedance (Biodynamics BIA 450, Biodynamics Corporation, Washington, USA) to collect body composition data, indirect calorimetry (Quark CPET, Cosmed, Italy) to collect resting metabolic rate and time and frequency domain variables of heart rate variability using a heart rate monitor (SmartLab, HMMGroup, Germany); b) Exercise, using the 6-minute step test with a gas analyzer (Quark CPET, Cosmed, Italy) breath by breath to assess physical and metabolic effort. To determine data normality, the Shapiro-Wilk test was used, with normal data represented by mean and standard deviation and non-normal data represented by median and interquartile range. For multivariate data analysis, principal component analysis (PCA) was used, employing the varimax rotation algorithm to create the components. The reduced value of each component was used to perform a simple linear regression analysis. Results: Thirty-seven individuals with OSAS (54.05% men), BMI 31.1 ± 5.31 kg/m2 and AHI 31.3 (11.3-61.6) were evaluated. The PCA analysis created 6 principal components (PC), which are: 1st PC: body composition; 2nd PC: cellular health; 3rd PC: physical effort; 4th PC: ventilatory reasons; 5th PC: sympathovagal stimulation; 6th PC: sympathovagal stimulation (very low frequency). The body composition indicators component (BMI, neck circumference, resting metabolic rate, body resistance, and capacitance) was associated with higher AHI (F[3,32] = 3.05; p = 0.01), with an adjusted r2 value of 0.22. Conclusion: Body composition is associated with the severity of OSAS, while the components of cellular health, physical effort, ventilatory ratios, sympathovagal stimulation, and very low frequency sympathovagal stimulation were not associated with the severity of the syndrome.

Associação entre características clínicas, funcionais e psicossociais com o risco de cronicidade dos sintomas em pacientes com dor lombar crônica não específica
(Universidade Federal do Pará, 2024-10-20) SILVA, Lucas Yuri Azevedo da; MAGALHÃES, Maurício Oliveira; http://lattes.cnpq.br/7766377002832983; https://orcid.org/0000-0002-7857-021X
Background: Low back pain is considered the leading cause of disability worldwide. Central sensitization is one of the mechanisms that explains how dysregulation in the central nervous system can modulate the chronicity of low back pain; however, it is unclear how clinical, functional, and psychosocial variables are associated with the risk stratification of low back pain chronification. Objective: To verify the association between low and high risk of symptom chronicity and clinical, functional, and psychosocial findings in patients with non specific chronic low back pain. Methods: This is a cross-sectional study applied to individuals with non-specific chronic low back pain, following the recommendations of The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE), conducted between April 2023 and June 2024. The Numerical Pain Rating Scale (NPRS) and the INSTRUTHERM DD2000 20K pressure algometer were used to assess pain intensity and threshold; the Roland-Morris Disability Questionnaire (QRM) to assess functional disability; the Start Back Screening Tool (SBST) for chronicity risk stratification; the Pain Catastrophizing Scale (PCS), the Tampa Scale for Kinesiophobia (TSK), and the Hospital Anxiety and Depression Scale (HADS). Descriptive statistics were performed, and correlation tests were conducted between SBST stratifications of chronicity and the scores from the evaluation instruments. Additionally, multinomial regression analyses were employed. Results: A total of 150 participants were included in the analysis. The correlation between low chronicity risk and clinical, functional, and psychosocial parameters showed statistically significant and moderate negative correlations for the QRM (r = -0.40) and PCS (r = -0.48). Significant, positive, and moderate correlations with high chronicity risk were observed for the QRM (r = 0.40) and PCS (r = 0.48), while positive and weak correlations were found for TSK (r = 0.39) and HADS (r = 0.27). Moreover, the multinomial regression analysis between high and low chronicity risk identified functional disability as a significant predictor for the elevated chronicity risk. For each one-unit increase in the disability questionnaire, the odds of being in the high-risk group increased by 8.8% (OR = 1.088, 95% CI: 1.003 - 1.181, p = 0.043). Additionally, catastrophizing was also a significant predictor. Each additional unit in the catastrophizing score increased the odds of being classified in the high-risk chronicity group by 10.0% (OR = 1.100, 95% CI: 1.049 - 1.154, p < 0.001). The model presented a significant intercept (β = -4.621, p < 0.001), indicating that, in the absence of predictor factors, the probability of being in the high-risk chronicity group is extremely low (OR = 0.009, 95% CI: 0.002 - 0.043). Conclusion: These findings suggest that the probability of being at high risk of chronicity compared to low risk was 36.8%, explained by functional disability and pain catastrophizing.

Atividade física, qualidade do sono e fatores associados à capacidade para o trabalho de fisioterapeutas da linha de frente contra a COVID-19
(Universidade Federal do Pará, 2021-06-28) MORAES, William Rafael Almeida; NEVES, Laura Maria Tomazi; http://lattes.cnpq.br/4235603520707156; https://orcid.org/0000-0002-3115-2571
INTRODUCTION: The COVID-19 pandemic highlighted the importance of physical therapy for the control and prevention of pulmonary and musculoskeletal complications, with emphasis on the specialty Respiratory Physical Therapy and Physical Therapy in Intensive Care. However, the physical and mental demands required for work on the front lines, as well as the changes in lifestyle in the face of the pandemic, may have negatively interfered with the physical therapists' ability to work. OBJECTIVE: To associate the level of physical activity, sleep quality, and demographic and occupational factors with the work ability of physical therapists on the front lines against COVID-19. METHODS: Analytical, cross-sectional and quantitative study. Brazilian physiotherapists working on the front lines against COVID-19 answered an online questionnaire that grouped four instruments: a) demographic, occupational and lifestyle data; b) the International Physical Activity Questionnaire (IPAQ); c) the Pittsburgh Sleep Quality Index (PSQI); d) the Work Ability Index (ICT). Data were analyzed and presented in descriptive statistics (absolute and relative values, mean, standard deviation) and associations between the ICT results and the independent variables, giving significance when p ≤ 0.05. The statistical software R version 4.0.0 was used. RESULTS: Answers were obtained from all regions of Brazil. There was no association between work ability and physical activity level, but inadequate work ability was associated with poor sleep quality (p < 0.001) and ICT and PSQI values showed a significant negative correlation (r = - 0.340; p < 0.001). In the adjusted analysis, work ability was associated with female gender (p = 0.018) and with a clinical diagnosis of previous COVID-19 (p < 0.001). CONCLUSION: In times of pandemic, reduced work ability is associated with poor sleep quality but not with physical activity level among frontline physical therapists against COVID-19. The results warn about the potential impact of sleep on the work of professionals who deal with the health of the population, highlighting the need for occupational health support strategies for physical therapists, especially in periods of public health crisis.

Breast cancer (BC) is a neoplasm that develops from the interaction between genetic mutations and epigenetic factors and has a significant impact on the physical and emotional health of patients. Surgical treatment, including mastectomy and breast-conserving surgery, can result in changes in muscle function, particularly in the upper limbs, affecting the quality of life (QoL) of female survivors. Analyzing muscle strength in post-BC surgery patients using isokinetic dynamometry to assess movements of the shoulder on the operated (ipsilateral) and non- operated (contralateral) sides is extremely important. This cross-sectional, observational study was conducted with 37 women who had undergone oncological breast surgery. Muscle strength was assessed using isokinetic dynamometry, considering shoulder flexion, extension, internal rotation, and external rotation movements at a speed of 60°/s. Statistical analysis was performed using STATA 18.0 software, with t-tests and Kruskal-Wallis tests to compare peak torque (PT) and total work (TW) indices between limbs. The results indicated that, overall, there were no significant differences between the involved and uninvolved limbs for flexion, extension, internal rotation, and external rotation movements, in terms of both total work and peak torque. Internal rotation showed a trend toward difference but did not reach statistical significance. No statistically significant differences in muscle strength were observed between the limbs involved and not involved in surgery. However, radical mastectomy was associated with higher peak torque in all movements, especially in external rotation, indicating that the type of surgery may impact muscle strength. The analysis also revealed that shoulder flexion strength was related to better QoL, although fatigue did not show a significant correlation. Post-surgical rehabilitation should take these differences in muscle function and the impacts of surgery into account, aiming to optimize recovery and improve patients' quality of life.

(Universidade Federal do Pará, 2023-04-05) ALMEIDA, Clara Narcisa Silva; NEVES, Laura Maria Tomazi; http://lattes.cnpq.br/4235603520707156; https://orcid.org/0000-0002-3115-2571
Introduction: Chronic kidney disease (CKD) often evolves silently at different stages, and stage 5 is the most advanced and severe, usually requiring renal replacement therapy. As the disease progresses, the metabolic alterations resulting from reduced renal function can lead to neuromuscular disorders and reduced functional performance in this population. Objectives: To assess neuromuscular function and oxidative stress in people undergoing an unplanned transition to stage 5 CKD at the start of hemodialysis. Methods: Cross-sectional study evaluating neuromuscular function (functional capacity [1-minute sit-to-stand test], peripheral muscle strength [isometric dynamometry of lower limbs], respiratory muscle strength [manovacuometry] and neuromuscular excitability [stimulus electrodiagnostic test]) and oxidative stress [malondialdehyde] in people in unplanned transition to stage 5 CKD who started hemodialysis on an emergency basis (CKD group) compared to people without CKD (control group) and them association. Results: Twenty-four participants, 14 in the control group without CKD (42 ± 12 years) and 14 in the CKD group (53 ± 18 years), were evaluated. The CKD group compared to controls without CKD present impaired functional capacity (13.8 ± 4.9 vs 36.7 ± 9.1 repetitions, p < 0.001), on peripheral muscle strength of lower limbs (knee extenders [12.3 ± 4.6 vs 23.5 ± 9 kgf], knee flexors [11.3 ± 3.2 vs 17.8 ± 4.3 kgf], dorsiflexors [8.7 ± 2.8 vs 16.7 ± 4.3 kgf] and plantar flexors [11.2 ± 2.5 vs 16.6 ± 4.4 kgf], all p < 0.001), expiratory muscle strength (60 ± 23 vs 83 ± 27 cmH2O, p = 0.02) and neuromuscular excitability (chronaxy of the vastus lateralis, 654 ± 230 vs 415 ± 190 μs, p = 0.008; chronaxy of the tibialis anterior, 600 [500 – 1000] vs 400 [300 – 400] μs, p = 0.001),. Inspiratory muscle strength (-70 ± 33 vs -87 ± 29 cmH2O, p = 0.7) and oxidative stress (3.51 ± 1.13 vs 3.53 ± 0.92 nmol/ml, p = 0.95) showed no significant differences. In the CKD group, functional capacity was influenced only by peripheral muscle strength, while expiratory muscle strength and functional capacity demonstrated influence on peripheral muscle strength. Conclusion: People in unplanned transition to stage 5 CKD who start hemodialysis on an emergency basis have altered in neuromuscular function. The findings of this study can guide screening and monitoring strategies for neuromuscular deficiencies and rehabilitation planning.

Avaliação da potência vertical de membros inferiores em pessoas com Parkinson
(Universidade Federal do Pará, 2024-12-23) SILVA, Vinicius Baia; MONTEIRO, Elren Passos; http://lattes.cnpq.br/0920248966438368; https://orcid.org/0000-0001-7757-6620
Parkinson's disease (PD) is considered neurodegenerative, polysomatic, and idiopathic, which affects the central nervous system, more precisely the dopaminergic neurons of the basal ganglia. The neural disorders of the disease cause neuromuscular declines, such as a reduction in motoneuron responses, potential action firing, muscle recruitment, power, strength, and muscle mass. Muscle power is fundamental in initiating movements, and its decline implies frailty, risk of falls, greater dependence, and low quality of life. In this context, it is relevant to evaluate muscle power in people with Parkinson's (PwP). However, using high- cost equipment that is difficult to transport and handle presents challenges for carrying out clinical assessments in this population. The evaluation of the vertical power of the lower limbs allows the interpretation of biomechanical mechanisms, such as strength, speed, and power. Clinically, the analysis of these aspects of Parkinson's disease is essential for rehabilitation strategies that emphasize the maintenance and improvement of these components. The literature reports that mobile applications are an alternative to specific instruments (for example, photoelectric cells, and goniometers). However, it is necessary to test the reproducibility and agreement of these instruments in populations with significant motor declines, such as individuals with Parkinson's disease (PD). Objective: To describe the vertical power of PcP through the performance of the vertical countermovement jump (CMJ) and evaluate the agreement in jump performance measurements by different evaluators (intra-evaluators) and between equipment (inter-instruments): a contact for vertical jumps and a My Jump 2® mobile app. Methods: The participants were 19 PwPs over 40 years old (15 men and 4 women), with PD staging between 1 and 3 according to the Hohn & Yearh Scale. The participants underwent clinical assessments: cognitive screening, anamnesis, and disease monitoring. For anthropometric assessments, we used a stadiometer, digital scale, and anthropometric tape measure. To assess performance, we used the CMJ vertical jump test, which was recorded simultaneously using the contact mat for vertical jumps and the My Jump 2® app installed on an IOS version 17.2 smartphone, recording at 240 Hz and 1080 HD. The volunteers were instructed to perform 3 consecutive jumps, with an interval of 120 seconds between each jump. For the statistical analysis, descriptive statistics were used to characterize the sample and then a mixed model was adjusted to assess the difference between the measurements. Next, the Bootstrap technique with 10,000 resamples was applied to calculate the limits of agreement, and histograms were generated to visualize the distribution of the Intraclass Correlation Coefficient (ICC). Finally, Bland-Altman plots were created to visualize the agreement between raters and instruments. All the intra-rater and later inter-instrument analyses were carried out using the R software. Results: As result, the values of ICC= 0.952 between evaluators and ICC= 0.948 between instruments indicate a very strong intra-evaluator and inter-instrument correlation. In both analyses, the limits of the confidence interval were close, with little variation in the estimates and reliability of the ICC. In the Bland-Altman analyses, there was agreement and consistency between assessors and instruments, with biases of 0.36 cm between assessors and -1.3 cm between instruments. Conclusion: Our results suggest that the My Jump 2® app is an alternative tool for assessing lower limb power using the CMJ vertical jump test in people with Parkinson's disease.

INTRODUCTION: Breast cancer is the most commonly diagnosed cancer, and the most common cause of death from cancer, in women worldwide. Despite the advancement of treatment, there are still many associated complications. OBJECTIVE: to analyze the influence of social, demographic factors, screening procedures and population coverage of primary care on breast cancer mortality in Brazil, and to verify the effect of physical therapy on clinical symptoms and range of motion in women undergoing mastectomy with axillary lymphadenectomy, after chemotherapy and radiotherapy. METHOD: Available and open access secondary data from the SUS Information and Informatics Department, SIDRA (IBGE Automatic Recovery System) and eGestor AB (Primary Care Information and Management) were analyzed. The medical records of 25 women (mean age 55 ± 14 years) after surgical treatment of mastectomy with axillary lymphadenectomy for the diagnosis of breast cancer were also analyzed. The signs and symptoms evaluated were pain, tenderness, phantom breast syndrome, heavy and swollen arm, lymphedema and axillary web syndrome. The range of motion of flexion, abduction, internal rotation and external rotation of the glenohumeral joint was also assessed. RESULTS: It was observed that the mortality rate is higher in brown women; in the Southeast and South regions; and it grows with increasing age. The North region has lower mortality and lower survival. The mortality rate did not decrease with the increase in the coverage of primary health care coverage and the number of biopsy procedures. However, the rate decreased with the increased execution of cytopathological analysis. In addition, physical therapy contributed to the reduction of pain resulting from the clinical-surgical treatment of breast cancer, and promoted an increase in the range of motion of the glenohumeral joint. CONCLUSION: The coverage of health services and the number of screening procedures are not correlated with the breast cancer mortality rate and physical therapy contributes to the improvement of pain and range of motion.

Understanding how school environment characteristics influence adolescent physical activity behaviors is essential for developing targeted interventions. The aim of this study was to investigate the associations between school environment characteristics and the levels of participation in Physical Education (PE) classes and active commuting to school. This is a cross sectional study with multistage sampling, involving 1,719 adolescents from 46 public and private high schools in the municipality of Belém, Pará. The time spent in PE classes and active commuting during the previous week was self-reported based on the National School Health Survey questionnaire. School environment characteristics were obtained through questionnaires completed by school administrators and researcher observation visits. Zero-inflated negative binomial regression models were used to address overdispersion and excess zeros in the data. The results indicated that the majority of students (55.0%) did not participate in practical PE classes, with only 37.6% reporting 30 minutes or more of activity per week. Regarding active commuting, approximately one-third of adolescents (34.6%) did not engage in this type of commuting. In the logit component of the adjusted models, factors associated with reduced odds of non-participation in PE classes included a higher number of PE teachers (OR = 0.79; 95% CI: 0.71–0.87), the presence of locker rooms (OR = 0.66; 95% CI: 0.54–0.83), and school accessibility (OR = 0.68; 95% CI: 0.54–0.86). For active commuting, the presence of sidewalks (OR = 1.34; 95% CI: 1.03–1.74) and bike racks (OR = 1.61; 95% CI: 1.26–2.05) increased the odds of non-engagement, while speed bumps (OR = 0.60; 95% CI: 0.43–0.82) reduced the odds of non-engagement. In conclusion, school environment characteristics have the potential to decrease non-adherence to practical PE classes among adolescents. However, active commuting behaviors may depend on factors beyond infrastructure, requiring further exploration.

The purpose of this master's dissertation was to investigate the influence of eccentric action velocity on subsequent concentric phase performance in trained elderly and young adult mass= 64.1 ± 6.9 kg) and 16 young adult women (age= 23.1 ± 2.1 years; height= 1.7 ± 0.3 meters; body mass= 61.2 ± 10.2 kg) were randomized using software (randomizer.org.br) to perform two conditions and intensities: (1) high velocity (HV) and (2) moderate velocity (MV) executed on the Smith machine bench press using 30% and 60% of 1RM to evaluate mean propulsive velocity (MPV), peak velocity (PV), and mean power (MP) performance. For all analyses, twoway repeated measures ANOVA was used. Results showed that performance for 0.30; p< 0.0001). In addition, PV (F= 18.77; ω²= 0.24; p< 0.001) and MP (F= 9.57; ω²= 0.13; to be more effective in increasing MPV (p< 0.001; d= 0.57) and MP (p< 0.001; d= 0.17) for MV. The main findings suggest that control of the eccentric phase appears to influence ABSTRACT women. To this end, 12 elderly women (age= 65.2 ± 4.2 years; height= 1.6 ± 0.4 meters; body MPV was superior for young adults compared to elderly only at 30% of 1RM (F= 24.2; ω²= p= 0.005) were superior for young adults compared to elderly at 60% of 1RM. HV was shown both young and elderly women (p< 0.001; d= 0.58), considering 30% of 1RM compared to subsequent concentric phase performance when light loads are applied (30% of 1RM), regardless of age group.

In Belém, these disparities may be exacerbated by the socioeconomic and demographic conditions characteristic of the Amazon region. This study investigated inequalities across different domains of physical activity and screen time among adolescents in Belém (PA), considering the wealth index, sex, and school administrative dependency, while also exploring the intersectionality of vulnerabilities across multiple dimensions. Data from 1,719 adolescents (49% girls, 58% from public schools) were analyzed. Prevalence rates were calculated for school-based physical education (≥1 day/week and ≥30 minutes), active transport (≥5 days/week), leisure-time physical activity (≥60 minutes/day), and excessive screen time (≥4 hours/day). Inequalities were assessed using the Slope Index of Inequality (SII) and absolute differences, with 95% confidence intervals obtained via bootstrap. Determinants included the wealth index (quintiles), sex, school administrative dependency, and the Jeopardy Index for multiple risk factors. Adolescents in the fourth quintile of the wealth index had higher prevalence rates for leisure-time activities (32.9%) and participation in physical education classes (39.9%), while active transport was more frequent among those in the first quintile (58.7%). Excessive screen time was more prevalent among girls (57.0%) and private school students (72.3%), whereas boys (46.5%) and public-school students (54.4%) had higher prevalence rates for active transport. Analysis using the Jeopardy Index revealed greater inequality in excessive screen time (66.2%) among girls attending private schools with higher socioeconomic levels, while boys in the same group showed higher prevalence of leisure-time activities (44.4%). Conversely, students with greater vulnerability according to the Jeopardy Index demonstrated a higher prevalence of active transport (57.0%). The greatest magnitude of inequality was observed for active transport (SII = 0.398; 95% CI: 0.324 to 0.466) and screen time (SII = -0.328; 95% CI: -0.405 to -0.258). Leisure-time activities (SII = -0.180; 95% CI: - 0.244 to -0.110) and physical education (SII = -0.104; 95% CI: -0.182 to -0.026) also exhibited significant inequalities, albeit with lower magnitudes, disproportionately affecting more vulnerable adolescents. In conclusion, physical activities and screen time are influenced by various layers of inequality, with boys of higher socioeconomic status being more active in leisure-time activities and girls more exposed to excessive screen time. Among the most vulnerable groups, higher rates of active transport were observed, potentially reflecting a need rather than a choice.

Determinantes de sarcopenia e fragilidade em pessoas com Parkinson no contexto amazônico
(Universidade Federal do Pará, 2025-03-26) SANTOS, Ana Carla de Matos; MONTEIRO, Elren Passos; http://lattes.cnpq.br/0920248966438368; https://orcid.org/0000-0001-7757-6620
Introduction: Aging is a natural process characterized by the progressive loss of tissue and organ function, increasing the predisposition to various diseases, including Parkinson's Disease (PD). Among the conditions associated with PD, sarcopenia and frailty stand out as relevant geriatric syndromes. Sarcopenia is defined by the progressive reduction of muscle mass, strength, and function, while frailty is characterized by greater vulnerability to stressors, impacting physiological reserve and functional capacity. Despite distinct concepts, both share pathophysiological mechanisms affecting muscle power, such as chronic inflammation, oxidative stress, and neuromuscular degeneration. The absence of accessible and standardized instruments for screening these geriatric syndromes in clinical settings represents a challenge, especially considering the applicability of these methods in different sociodemographic contexts, such as in the Amazon region. Objective: This study aimed to analyze the profile of sarcopenia and frailty, as well as possible associations with clinical parameters of PD and sociodemographic aspects in people with Parkinson's disease (PwP) living in the community of a state in the Amazon region. Methods: This is an observational and analytical study, including PwP over 40 years of age, of both sexes. Initially, an anamnesis was conducted to collect sociodemographic data, followed by using instruments such as SARC-Calf and Short Physical Performance Battery (SPPB) for sarcopenia screening, and Fried's Phenotype for frailty screening. Vertical power was analyzed using the My Jump 2 app, considering parameters such as jump height, flight time, take-off velocity, force, and power. For statistical analysis, Spearman's correlation coefficient was used to identify possible associations between sarcopenia and frailty with clinical and sociodemographic variables. Subsequently, logistic regression was conducted to assess whether body mass predicted sarcopenia. Regarding frailty, none of the predictors were significant. All analyses were performed using SPSS software (IBM, Greenville, SC), version 25.0. Results: A total of 24 people with Parkinson's disease (PwP) were evaluated, 83.3% of whom were male, with a mean age of 66.35 years, living with a spouse and children (37.5%). They were stratified into sarcopenic (29.2%) and non- sarcopenic (70.8%) groups. An association was observed between sarcopenia and body mass (OR = 1.438; CI = 1.045 – 1.980). Regarding frailty, the prevalence was lower than reported in the literature, possibly due to the small sample size. Conclusion: This study concluded that body mass was a risk predictor for sarcopenia in PwP, and that the sample profile was predominantly male, with a higher occurrence of falls in stage 2 of PD and a high prevalence of pre-frailty. Despite the absence of other significant predictors for sarcopenia and frailty, the findings highlight the need for clinical standardization and universal diagnostic criteria, considering regional sociodemographic aspects.

Diminuição nas manifestações físicas e psicológicas da síndrome pré-menstrual e de seu impacto funcional através do protocolo de dose mínima
(Universidade Federal do Pará, 2024-04-08) SILVA, Eliane Aragão da; PIRES, Daniel Alvarez; http://lattes.cnpq.br/4487383675643868; https://orcid.org/0000-0003-2163-5606
Premenstrual Syndrome (PMS) is a set of more than 200 symptoms that involve behavioral factors and somatic, emotional, and cognitive symptoms that are directly related to hormonal changes that occur in the premenstrual period. Amid stressful situations experienced throughout life, strategies are needed to face and adapt to such events. How one chooses to deal with situations is characterized by coping strategies. Women with PMS use different coping strategies compared to women without PMS, making it necessary to understand which strategies are useful for dealing with premenstrual distress and which can be actively modified with methods such as physical activity. The beneficial effect of exercise on PMS symptoms is the reduction of psychological symptoms, but studies with the application of controlled, long-term protocols are still needed. Minimum dose training is like “training snacks”, with summarized training, below that is recommended by global institutions, providing physical and psychological gains to practitioners, compared to a sedentary life. The objectives of the study are: a) to analyze the effects of a minimum dose protocol of 8 weeks on the psychological symptoms of PMS, and b) to identify which coping strategies were used by women affected by PMS during a minimum dose protocol of eight weeks. After selection by inclusion criteria based on information from a Sociodemographic Questionnaire, the PMS Symptom Screening Questionnaire (Premenstrual Symptom Screening Tool - PSST), and the Physical Activity Readiness Questionnaire (PAR-Q), 33 university students were affected. by the SPM, they were referred to two groups: the Resistance Training Group (GTR), which carried out a resistance training program, and the Control Group (CG), which carried out physical tests and filled out questionnaires. Both responded to the questionnaire (Premenstrual Symptom Screening Tool - PSST) on day 1 of their cycle for two menstrual cycles and the coping strategies questionnaire (Brief Cope), given at the end of every week for two months. For data analysis, the linear mixed model was used using Restricted Maximum Likelihood (REML) with the application of the ANOVA III table and Tukey's post hoc for the analysis of PMS symptoms. To analyze coping strategies, the linear mixed model was used for each domain, with descriptive and exploratory analysis. The program used for the analysis was R Studio. The results of the analysis showed significant differences in physical and psychological manifestations, in the second moment, with a reduction in symptoms in the GTR compared to the CG. Differences were also noticed in the functional impacts of symptoms, in the second moment, with a reduction in impacts in the GTR compared to the CG. In the coping analysis, constancy was observed in the choice of strategies, demonstrating that it was not influenced by the minimum dose protocol. We conclude that the practice of resistance training with the minimum dose method helps in the treatment of PMS symptoms by reducing physical and psychological manifestations as well as the functional impact of the symptoms on the lives of those affected. The chosen coping strategies seem to remain constant, not being influenced by the minimum dose protocol.

Warming up is an important part of an athlete's preparation, especially before a competition. Combat sports, such as wrestling, require high levels of muscular power during combat. Inducing Post-Activation Performance Enhancement (PAPE) before competition can benefit the athlete by enhancing their muscular power levels. To induce PAPE it is necessary to define a conditioning activity to be used, in this sense the objective of the present investigation was to compare the acute effect of Post-Activation Performance Enhancement (PAPE) from the squat jump (SJ), drop jump (DJ) and Sound stretching (AD) in the Special Wrestling Fitness Test (SWFT) in senior Olympic wrestling athletes. To this end, 20 adult male participants, aged between 23 and 35 years old, voluntarily participated in this research. Each participant underwent four visits, which were organized as follows: 1) familiarization; between 2 and 4) SWFT protocol and protocol for each conditioning activity. The conditioning activities were randomized, including squat jump, drop jump and dynamic stretching. Each visit had a minimum interval of 48 hours. The SWFT protocol was performed before and after each conditioning activity. Data were analyzed with ANOVA-MR. It was found that the SWFT index for both vertical jumps were similar and lower than in AD, demonstrating that the performance of vertical jumps, as a conditioning activity, in PAPE were better (p<0.001). Even so, the interval time used of 3 minutes was enough to enhance the fighters' performance in vertical jumps, but not in AD. In each conditioning activity, the number of throws performed pre- and post-SWFT reduced over the three series (p<0.001). However, the SJ and the DJ in the post-SWFT had a greater number of throws made, while in the AD the number of throws was lower than in the pre-SWFT (p<0.001). Based on these findings, it is possible to infer that both vertical jumps promote PAPE with a minimum interval of 3 minutes, while AD does not. Therefore, using vertical jumps during warm-up strategies to enhance muscular power in wrestling athletes is a viable, easy and effective way.

Resistance Training (RT) is a modality that has high applicability and efficiency in physical, clinical and functional contexts. The scientific advance in this modality, a series of recommendations for the manipulation of variables and dosage of RT emerged for different purposes and population. However, it is not clear how these RT prescription guidelines affect responsiveness, characterized like an individual's particular capacity for respond to/benefit from an intervention, for a given measure. Therefore, the aim of the study was to carry out a systematic review to investigate the effect of RT on the responsiveness of healthy adults, in variables of strength, power, functionality and muscle hypertrophy, based on the prevalence rate. Only randomized clinical trials, in English, indexed in the PubMed/MEDLINE, SCOPUS, EMBASE and SPORTDiscus databases, published until June 2021, were considered. The study was registered in the International Prospective Register of Systematic Reviews (PROSPERO), identified by the code CRD42021265378. After the study selection process, the risk of bias was analyzed using the ROB2 tool from Chrocrane. After the search strategy, 3033 studies were found and, through the screening process, 13 studies were selected for systematic analysis. As for the effectiveness of the RT, the prevalence range for non-responders individuals to muscle strength was 0% to 44%, for hypertrophy 0% and 84% and functionality 0 to 42%, while, for muscle power, only one study investigated the responsiveness rate and reported 37%. Therefore, it seems that alterations to muscle hypertrophy may be less sensitive to RT, compared to other variables. Larger RT volume tends to be more effective overall, however intensity may be a key factor in some cases. However, the principle of specificity can be the most important aspect to effectivity of TR in these variables of interest. Moreover, it is important to consider methodological and statistical aspects when analyzing outcomes in responsiveness.

Efeito do exercício físico na força muscular, massa muscular e desempenho físico em pessoas sarcopenicas com câncer: uma revisão sistemática
(Universidade Federal do Pará, 2024-12-20) GUEDES, Laerte Jonatas Leray; NEVES, Laura Maria Tomazi; http://lattes.cnpq.br/4235603520707156; https://orcid.org/0000-0002-3115-2571
Cancer is the leading cause of secondary sarcopenia, representing a growing problem among people diagnosed with cancer. This condition is associated with unfavorable outcomes both in relation to disease progression and to the various types of cancer treatment. Physical exercise is recommended by several guidelines for cancer patients. However, the guidelines do not present specific recommendations for sarcopenia, and few systematic reviews have explored this topic. In addition, the effect of physical exercise on improving sarcopenia (muscle strength, muscle mass and physical performance) in cancer patients is not yet fully elucidated. Objective: To verify the effect of physical exercise on muscle strength, muscle mass and physical performance in sarcopenic people with cancer. Materials and methods: The study is a systematic review, we used the acronym PICOS as the inclusion criterion, population: adult patients diagnosed with cancer and diagnosed with sarcopenia; Intervention: physical exercise alone or associated with other interventions; control: patients in usual care, without treatment or without physical exercise; outcome: muscle strength, muscle mass, and physical performance; Types of studies: randomized controlled clinical trials. The databases used were Pubmed, Excerpta Medica database (EMBASE), Cochrane (CENTRAL), Physiotherapy Evidence Database (PEDro), Latin American and Caribbean Health Literature in Health Sciences (LILACS), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and SPORTDiscus. For gray literature, Clinical trials.gov, Proquest, and the Catalog of Theses and Dissertations of the Coordination for the Improvement of Higher Education Personnel were checked, with no language or time limit. The searches were conducted until October 10, 2024. The risk of bias of the included studies was assessed by the Cochrane Risk of Bias Tool 2 and the level of evidence by the Grading of Recommendations Assessment, Development and Evaluation. Qualitative (narrative) synthesis was performed in the review, presenting the effect measures extracted from the studies individually. Results: Eight randomized controlled clinical trials were included. Three studies demonstrated an effect on skeletal muscle mass index in favor of resistance exercise (MD = 0.32 kg/m2, 95% CI [0.04; 0.60), resistance and aerobic exercise on appendicular skeletal muscle mass index (MD = 2.4 kg/m2, 95% CI [4.1; 1.30]) and resistance exercise associated with protein supplementation (MD = 0.03 kg/m2, 95% CI [0.1 0.5]). There were no differences between the intervention and control groups for the variables muscle strength and physical performance. The included studies presented risk of bias with some concerns and high risk. Additionally, all outcomes received a low level of evidence in GRADE. Conclusion: Although exercise appears to be safe and three articles indicate a possible effect on muscle mass, the studies did not have sarcopenia as a primary outcome, with prevalence rates of <50% of sarcopenic individuals in 7 studies. Thus, there is still a lack of evidence on the real effect of physical exercise on sarcopenia in cancer patients.

Os efeitos agudos do treinamento intervalado de alta intensidade (HIIT) na cognição e na variabilidade da frequência cardíaca de crianças com ansiedade e depressão
(Universidade Federal do Pará, 2022-06-29) SILVA, Luisa Matos da; TORRES NETO, João Bento; http://lattes.cnpq.br/7874863858825807; https://orcid.org/0000-0002-9155-9445
Anxiety and depression (AD) are the most common and debilitating mental health problems in childhood and adolescence. High-intensity interval training (HIIT) has been studied as a component of improving inhibitory control, commonly affected in children with AD. The aim of this study was to investigate the acute effects of HIIT on heart rate variability (HRV) and on inhibitory control of school children with AD. We performed a randomized crossover trial with 71 children aged 9 to 13 years, 36 girls and 35 boys, where children performed an acute HIIT training and stretching protocol (control) on different days. We used the RCADS questionnaire score to classify children for AD and analyzed this classification of the dispersion by quartiles (upper and lower). Inhibitory control was evaluated using the Flanker test before and after exercise, and HRV was obtained using a heart rate monitor and analyzed using the Kubios software. The effect of exercise was analyzed using pairwise estimation statistics and repeated measures ANOVA. Our results demonstrate that an acute HIIT produced improving effects on inhibitory control in both groups, such as the accuracy of incongruous latency responses, as well as the cost of conflict; in addition to improved congruent latency for the CAD group. The HRV results demonstrate that acute HIIT was not able to improve HRV, but there was a positive effect after stretching that needs further investigation in future works.

Os efeitos do treinamento pliométrico sobre o desempenho do tempo de resposta em praticantes de esportes de combate de percussão
(Universidade Federal do Pará, 2025-02-12) MACHADO, Hugo Enrico Souza; PENNA, Eduardo Macedo; http://lattes.cnpq.br/3746450308327976; https://orcid.org/0000-0003-0058-7967
Reaction time is an important variable in combat sports, as it depends on both central mechanisms (perception and information processing) and peripheral mechanisms (movement execution). Additionally, the ability to maximize force production in the shortest possible time can enhance muscle contraction speed and make strikes faster. However, little is known about the effects of power training adaptations on overall reaction time performance in combat sports practitioners. Thus, this study aimed to investigate the effects of six weeks of plyometric training on the performance of simple and choice reaction times (SRT and CRT, respectively) in striking combat sports athletes. For this purpose, 16 volunteers were divided into two groups: traditional training group (TTG = 8) and TTG + plyometric training group (TTG+PLYO = 8). Participants were assessed at two time points (pre- and post-intervention) for SRT and CRT in specific semicircular kick tasks, as well as for countermovement jump (CMJ), squat jump (SJ), horizontal jump (HJ), and reactive strength index (RSI). The TTG+PLYO group followed a six-week plyometric training (PT) program, training twice a week in addition to their regular sport-specific training. In contrast, the TTG group continued with their regular training only. For statistical analysis, a two-way ANOVA (group × time) and an independent t-test were used to evaluate the percentage of variation between groups. A significance level of p < 0.05 was adopted. Results showed no significant group × time interaction for SRT (F = 0.73; p = 0.40; η2 = 0.003) or CRT (F = 0.04; p = 0.83; η2 = 0.001). Regarding jump performance, only SJ presented a significant group × time interaction (F = 6.16, p = 0.026, η2 = 0.01), with an increase in jump height observed only in the TTG+PLYO group (pre = 30.3 ± 5.7 cm, post = 33.4 ± 5.8 cm, p = 0.01) and a significant difference in percentage variation (TTG: 0.4 ± 4.8%; TTG+PLYO: 9.1 ± 8.1%; p = 0.02). Additionally, RSI showed a significant variation only for the TTG+PLYO group (TTG = -2.3 ± 8.3%; TTG+PLYO = 24.4 ± 31.4%; p = 0.03). We conclude that six weeks of PT improved the physical performance related to power production in the TTG+PLYO group, without significant improvements in overall specific reaction time performance in combat sports practitioners.

Eficácia da terapia manual aos exercícios para melhora da intensidade da dor e incapacidade funcional em pacientes com dor lombar crônica inespecífica: Revisão sistemática e metanálise
(Universidade Federal do Pará, 2025-02-27) SANTOS, Emmanuele Celina Souza dos; MAGALHÃES, Maurício Oliveira; http://lattes.cnpq.br/7766377002832983; https://orcid.org/0000-0002-7857-021X
Low back pain is among the main causes of global disability, with symptoms lasting more than 12 weeks. Manual therapy is a recommended treatment strategy, in addition to therapeutic exercises, which have shown beneficial neurophysiological effects. However, it is still unclear whether there are benefits of manual therapy and exercises compared to isolated exercises. Objectives: To evaluate the effectiveness of manual therapy combined with exercises versus isolated exercises for improving pain intensity and functional disability in patients with chronic nonspecific low back pain. Methods: This is a systematic review. Searches were performed in the following databases: PubMed, PEDro, Cochrane, Library, EMBASE, Web of Science and CINAHL. Two independent reviewers selected randomized clinical trials that verified improvement in pain intensity and/or functional disability in patients with chronic nonspecific low back pain undergoing manual therapy and exercises compared to isolated exercises. Results: In the end, five randomized clinical trials were included, totaling 260 participants. It was possible to conduct a meta- analysis, which demonstrated that manual therapy associated with exercises compared to isolated exercises was not effective in the pain outcome (SMD = -0.87, CI: -1.87; 0.12, I2 = 90%), but the disability outcome showed statistically significant results in the short term (SMD = -0.73, CI: -1.05 to -0.42, I2 = 0%) and long term (SMD = -1.13, CI: -2.06; -0.19, I2 = 80%). However, these findings were classified as having moderate to low GRADE evidence. Conclusion: Patients who performed one therapy associated with the other compared to isolated therapy did not obtain improvement in pain intensity, but the functional disability outcome obtained statistically significant results in the short and long term; these findings proved to be beneficial. Although the overall quality of evidence in the studies was moderate to very low, these findings represent an important field of research that should be guided by studies with more participants and homogeneous methods of analysis and this can guide the management of low back pain.
