(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.

Individuals with vestibular symptoms present unstable gait, imbalance and one way to measure an individual's level of imbalance is through baropodometry, widely used in clinical practice to map the area of plantar pressure through graphic records and determine displacements and oscillations. of the center of pressure through stabilometry. Furthermore, balance and anxiety are related, as they share the same central neural circuits. Thus, psychological complaints such as anxiety and depression are common in individuals with dizziness. Therefore, the present study aims to analyze the motor, functional and emotional characteristics of individuals with vestibular symptoms. The analysis of plantar pressure and center of pressure was carried out using baropodometry and stabilometry on a force platform (BaroScan®, Londrina, Paraná, Brazil) and the BaroSys software, while for functional analysis we used the TUG test and the aspect functional of the DHI questionnaire and for emotional analysis the emotional aspect of the DHI. We found that individuals with vestibular symptoms have flat feet, with higher values of maximum pressure, mean pressure, maximum pressure in the midfoot and rearfoot and mean pressure in the rearfoot when compared to people without vestibular symptoms. Furthermore, individuals with vestibular symptoms have reduced functional mobility and a greater risk of falling, in addition to having compromised emotional and mental health, with signs of anxiety and mild to moderate depressive symptoms in the majority of individuals when compared to individuals without vestibular symptoms.

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 bioelétrica dos músculos do assoalho pélvico durante o uso de educador vaginal inovador: estudo transversal
(Universidade Federal do Pará, 2022-11-08) DUARTE, Natália de Souza; MELO NETO, João Simão de; http://lattes.cnpq.br/1547661999153615; https://orcid.org/0000-0002-4681-8532
The pelvic floor needs an integral anatomical structure due to its multiple functions. Therefore, innovative equipment is needed to improve this structure. The aim of this study was to analyze the effects of using the innovative iGeni vaginal trainer on the bioelectrical activity of the pelvic floor muscles, in addition to analyzing the different hip positions and interference factors such as age group, childbirth, sexual activity, urinary incontinence and menopause. For this, a cross-sectional study was designed, composed of 30 women, who were evaluated using the following instruments: evaluation form, International Consultation On Incontinence Questionnaire - Short Form and surface electromyography. The collected findings were: RMS of the 5-second period of contraction, peak RMS values, area values, %MVC (RMS normalized by peak signal) and median frequency. These findings were compared without and with the use of iGeni, in anteversion, neutral and retroversion pelvic positions. The results showed that the use of iGeni increased the electromyographic activity of the pelvic floor muscles in the neutral position. Women in conditions of greater tendency to dysfunction of this musculature also benefited, increasing bioelectrical activity under specific conditions. It was then concluded that this innovative biofeedback equipment was effective in the greater recruitment of muscle fibers and that it has greater effectiveness in the neutral position of the hip, being able to be an effective ally in the training of this musculature.

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.

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.

(Universidade Federal do Pará, 2023-04-28) AZEVEDO, Antenor Barbosa Calandrini de; PENNA, Eduardo Macedo; http://lattes.cnpq.br/3746450308327976; https://orcid.org/0000-0003-0058-7967; COSWIG, Victor Silveira; http://lattes.cnpq.br/0097939661129545; https://orcid.org/0000-0001-5461-7119
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.

(Universidade Federal do Pará, 2024-12-27) SILVA, Lucas Fernando Alves E; CRISP, Alex Harley; http://lattes.cnpq.br/1187580727139009; https://orcid.org/0000-0003-4683-9576
Inequities influence various aspects of health, including physical activity and sedentary behaviors among adolescents. 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.

(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.

Dor Musculoesquelética na Coluna Vertebral em Crianças e Adolescentes: uma análise de rede
(Universidade Federal do Pará, 2024-08-27) GOMES, Marcella Veronnica Pereira; MAGALHÃES, Maurício Oliveira; http://lattes.cnpq.br/7766377002832983; https://orcid.org/0000-0002-7857-021X
Introduction: Musculoskeletal pain is common in children and adolescents, with prevalence ranging from 4% to 40%. Back pain-related symptoms rank 5th in terms of years lived with disability among children aged 10 to 19 years, affecting approximately 2.443 million people. Additionally, it is associated with high healthcare costs and can lead to persistent pain in adulthood. Objective: To analyze the relationship between musculoskeletal pain in the spine in children and adolescents through a network approach. Methods: The study population consists of children and adolescents of both genders, who are regularly enrolled in elementary and high school. Children and adolescents of both genders aged between 10 and 16 years were included. The Back Pain and Body Posture Assessment Instrument (BackPEI-CA) and the Instrutherm pressure algometer, model DD-500, were used to assess pain intensity and threshold, respectively. Data were tabulated, and JASP was used for statistical analysis. A network analysis was conducted to investigate descriptive relationships between individual and contextual factors with self-reported symptoms of back and neck pain. Results: 185 participants were included in the analysis. The network analysis observed that the variable 'Lower Back Pain' was negatively correlated with 'Family Pain History' (-0.14) and positively correlated with 'Sex' (0.19) and 'Neck Pain' (0.12). The 'Sitting Position When Using Cell Phone/ tablet' showed a negative correlation with 'Neck Pain' (-0.19). A negative correlation was observed between 'Sex' and 'Physical Activity Outside School'. Centrality metrics indicated that 'Age' (betweenness = 1.420) and 'Sex' (betweenness = 1.278) had the highest betweenness values. Conclusion: The study concludes that sex is a significant variable in back pain among children and adolescents, with a higher prevalence among girls, possibly due to sexual maturation and lower levels of physical activity compared to boys, who are more active. Additionally, the pain is influenced by poor posture while writing at school and using electronic devices. However, the results should be interpreted with caution due to the limitations of the analysis.

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 da suplementação aguda de guaraná (Paullinia Cupana) e de uma dose equivalente de cafeína sobre parâmetros de potência muscular na execução do exercício supino reto
(Universidade Federal do Pará, 2024) COLAÇO, Fernando Sampaio; PENNA, Eduardo Macedo; http://lattes.cnpq.br/3746450308327976; https://orcid.org/0000-0003-0058-7967
Introduction: Guarana (Paullinia Cupana) is a natural substance rich in caffeine and other bioactive components. It is known that its acute ingestion can improve cognitive performance and effort perception parameters, but it is still unclear whether this ingestion can be efficient as an ergogenic substance in the production of muscular power, and whether this possible ergogenic effect is due to its caffeine concentration Objective: The objective of the present research was to compare the effect of acute ingestion of Guaraná (Paullinia Cupana) with an equivalent dose of caffeine on muscle power parameters. Methods: 34 individuals (18 to 35 years old) practicing resistance training were recruited and randomized into three experimental situations: PLACEBO (PLA); 500mg of guarana (GUA-500, containing 130mg of caffeine) and 130mg of caffeine (CAF-130). The individuals underwent a familiarization session with the bench press exercise performed on the Smith machine, in which the individuals' 1RM value and the optimal load for power production were measured. After a minimum interval of 48 hours from the 1RM test and optimal load, the individuals performed, on different days, the three experimental sessions in a randomized order: acute ingestion of caffeine, placebo or Guarana. Each experimental situation had a minimum washout interval of two days. A percentage of optimal load for power production was estimated through a progressive test on the bench press using only the bar, 30%, 40%, 50% and 60% of 1RM in order to identify the best load to perform 3 sets up to 40% of the loss of movement speed, with a 5-minute break between sets. Before performing the physical task, the individuals performed two sets of five repetitions using the load identified as optimal, with a 3-minute break between each set. warm-up series. Participants performed the concentric phase of movement performed at maximum intentional speed, and the eccentric phase lasting 2 seconds, in which the following variables were measured: average power (Watts), peak power (Watts), peak speed (m/s), and average propulsive speed (m/s). Results: Regarding the number of repetitions achieved between the experimental situations, no statistically significant difference was identified between the factors capsule ingested (F(2, 264) = 1.4689, P = 0.2320; partial η² = 0.01); between the three series performed (F(2, 264 = 0.5775, P = 0.5620) and in relation to Capsule: Series (F = 0.2937, P = 0.8819), in relation to Peak Power, the analyzes did not detect any significant effect on the values Capsule (F (2,264) = 0.0908; P = 0.7479), Series (F (2, 264) = 1.5053; P = 0.2238) and for the interactions Capsule: Series (F (4, 264) = 0.7674; P = 0.5453), regarding Average Power, the analysis did not detect significant effects for the Capsule factors (F (2, 264) = 0.028; P = 0.972; partial η² < 0.01), Series (F (2, 264) = 1.187; P = 0.306; partial η² < 0.01), and for the Capsule interaction: series (F (4,264) = 1.266; P = 0.283; partial η² = 0.02), as for Peak Speed, the analysis indicated no effect for the Capsule factor (F (2,263) = 1.162; P = 0.314; partial η² < 0.01), a significant effect for the factor Series (F (2, 263) = 3, 479; P = 0.03; partial η² = 0.03), in the Capsule:series interaction analysis (F (4, 263) = 1, 337; P = 0.256 ; partial η² = 0.02), no significant effect was identified. With regard to Average propulsive speed, no significant differences were identified for the factors Capsule (F (2, 264) = 0.401; P = 0.669; partial η² = 0.01), Series (F (2,264) = 1 , 327; P = 0.266; partial η² < 0.01) and for the Capsule: series interaction (F (4, 264) = 1.199; P = 0.311; partial η² < 0.01). Conclusion: Supplementation with 500mg of Guarana containing 130mg and 130mg of caffeine alone did not trigger any ergogenic effect on muscle power parameters and bench press speed.
