(Universidade Federal do Pará, 2025-02-26) SOUZA, Naicha Stefanie Félix; CRISP, Alex Harley; http://lattes.cnpq.br/1187580727139009; https://orcid.org/0000-0003-4683-9576
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.

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.

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.

Efeito agudo do aprimoramento do desempenho pós-ativação (PAPE) a partir do Squat Jump, Drop Jump e Alongamento Dinâmico no Special Wrestling Fitness Test (SWFT) para atletas de Luta Olímpica
(Universidade Federal do Pará, 2024-04-26) COSTA, Marcus Vinicius da; COSWIG, Victor Silveira; http://lattes.cnpq.br/0097939661129545; https://orcid.org/0000-0001-5461-7119
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.

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.

(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.

Mental fatigue (MF) is a psychobiological state caused by prolonged and demanding cognitive activity, characterized by feelings of tiredness and lack of energy induced by periods of demanding cognitive activity. MF negatively affects decision-making in sports, as these effects have been associated with a reduction in the performance of executive functions, which are conceptualized as a set of cognitive processes used to plan and carry out actions to achieve a goal. In this context, it is known that the performance of executive functions has been strongly associated with the decision-making of soccer referees, so understanding whether MF reduces the cognitive performance of referees is relevant. Thus, the aim of this study was to investigate the effects of mental fatigue and simulated physical task on soccer referees, on response time in a test that evaluates executive functions, and subjective perception of effort. Twelve professional regional soccer referees participated in the study, and made three visits to the laboratory, the first visit for evaluations and familiarization with the experimental protocols, and signing of the Informed Consent Form (ICF). In the 2nd and 3rd visits, the participants were exposed to two experimental conditions, mental fatigue or control, in a cross-over and randomized way. Therefore, in the MF condition, referees performed the Stroop Test and in the control condition, they watched an emotionally neutral video, and after these conditions, they were required to perform executive function tests simultaneously with the simulated physical task for soccer referees. The results revealed that there was no effect of mental fatigue on the performance of executive functions (P = 0.395). However, higher perceptions of effort were found in the mental fatigue condition (P = 0.018). In this sense, the present study shows that although mental fatigue alters the subjective perception of effort, there was no impairment in the executive functions performance of soccer referees.

The potentiation of functional capacity occurs through the insertion of the individual in physical activity, generating positive impacts on independence, autonomy, quality of life, functionality, self-esteem, social participation and greater health care, however there are facilitating factors and barriers. Objective: To identify the environmental, functional factors and level of physical activity of people with physical disabilities in rehabilitation and sports centers in the Northern Region. Method: Performed in a motor program for people with disabilities in the city of Manaus-Amazonas and at a Rehabilitation Center in Belém-Pará. Individuals with physical disabilities, of congenital or acquired origin, of both sexes, aged between 18 and 60 years, who performed physical and/or sports activity for at least 6 months, participated of this study. Where sociodemographic data were collected and three questionnaires were applied, namely: WHODAS 2.0, Physical Activity Scale for People with Physical Disabilities (PASIPD) and Measure of the Quality of the Environment (MQE). The sample consisted of 41 participants, which 61% were male, with a mean age of 43,1 (±13,1) years, mean time of injury 17,0 (±12,8) years, single, with income only social benefits or retirement, had completed high school and 26,8% had a diagnosis of spinal cord injury. All data were processed in the jamoviproject 2021 Software (version 2.2), applying the Shapiro-Wilk normality test and Pearson's Linear correlation test. Result: Regarding functionality, there was a predominance of mild difficulty in relation to cognition, self-care, interpersonal relationships, activity of daily living and participation. Noting that the mobility domain was the only one with moderate difficulty. Considering a level of metabolic equivalent physical activity below 30 MET/h/day. There was a correlation between domains related to functionality and environmental factors barriers, but there was no connection between functionality, level of physical activity and facilitating environmental factors. Conclusion: The barrier factors present in the daily lives of people with physical disabilities directly impact functionality, in the aspect of self-care, interpersonal relationships, mobility, activity of daily living and participation.

Sitting volleyball is a paralympic sport that has shown significant growth in competitive terms in recent years, increasing the need for methods of evaluating technical-tactical aspects and physical fitness that help in monitoring the level of performance and increase in sports performance in the modality. The present systematic review was conducted in accordance with the guidelines of the Main Items for Reporting Systematic Reviews and Meta-Analyses (PRISMA) and aimed to identify and analyze indicators of performance and physical fitness in sitting volleyball players. The searche was carried out in four databases (Scopus, Pubmed, Web of Science and Scielo) and studies that quantitatively evaluated performance indicators or physical fitness components in sitting volleyball athletes of any gender, age or competitive level were included. The methodological quality of the articles included was evaluated by the Critical Review Form for Quantitative Studies (LAW et al., 1998) and the results presented through narrative synthesis. In total, 37 studies were included, with an average quality score of 72.25%. The findings showed that attacking and blocking were the main terminal actions in sitting volleyball. Significant correlations between physical fitness measures (power, speed, agility, endurance, flexibility, reaction speed and body composition) with specific technical skills were identified. While limited evidence indicates that: male athletes perform better than female athletes; that elite athletes are physically and technically superior to sub-elite ones. In addition, the studies did not point out significant differences in the effectiveness in game actions between athletes of different functional classes.

Influência de fatores socieconômicos na percepção de níveis de estresse, ansiedade e depressão em atlestas de futebol feminino
(Universidade Federal do Pará, 2023-04-20) SOUZA, Edielen de Lima; PIRES, Daniel Alvarez; http://lattes.cnpq.br/4487383675643868; https://orcid.org/0000-0003-2163-5606
Football is one of the most widespread sports in the world. The female audience is gaining greater relevance. Mental health is an integral dimension of athlete well-being and performance and cannot be separated from physical health. The effects of stress, anxiety and depression in athletes can be severe and disabling. The assessment and management of mental health in athletes should be accessible for early intervention and improvement of the quality of the sporting environment. Thus, this research aimed to analyze the influence of age, education and paid activity on the perception of levels of stress, anxiety and depression in female soccer players. Data collection took place during the Paraense Women's Football Championship with 89 athletes. The athletes answered a sociodemographic questionnaire and the Portuguese versions of the following instruments: Perceived Stress Scale (PSS), Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI). Data analysis was performed using the GraphPad Prism 9.5.1 software. To correlate age, schooling and paid activity outside football with stress levels, the Fisher's exact test was used. To correlate age, education and paid activity outside of football with levels of anxiety and depression symptoms, Pearson's chi-square test was performed. The significance index used was p<0.05. Age and education showed no correlation with the perceptions of the psychological variables analyzed in this study. The presence of paid activity outside of soccer interfered only with the perception of moderate anxiety symptoms (p= 0.0471). When analyzing perceptions of stress, anxiety and depression in female soccer players, there is no difference in variability related to age and education. The presence of paid activity is a factor that deserves attention because it influences the perception of moderate anxiety in female soccer players, despite not interfering with the perceptions of stress and depression.

Monitoramento de carga interna e respostas físicas e fisiológicas ao treinamento de CROSSFIT®
(Universidade Federal do Pará, 2021-12-20) CASTANHEIRA, Luísa Freire da Silveira; COSWIG, Victor Silveira; http://lattes.cnpq.br/0097939661129545; https://orcid.org/0000-0001-5461-7119
CrossFit® is a training program recognized for its rapid growth in popularity in competitive and non-competitive forms, with the goal of developing different fitness domains simultaneously. Accurately and effectively identifying the effect of this training is indicated to periodically analyze the responses of a subject to a given overload, to safely prescribe and control training, and to promote adaptations. However, in this training model this is still not entirely clear, and a different response is expected because it is a self-regulated sport due to the high volume. Therefore, the objectives of this research was to describe the internal training load imposed on CrossFit® athletes over three months, and relate it to physical performance indicators. Additionally, to investigate the effect of training on aerobic fitness indicators and blood markers. To this end, competitive CrossFit® athletes were evaluated daily, weekly, and pre and post training. The instruments used were a notebook of perceptual measures regarding pain sensations, recovery, sleep quality and likely performance, heart rate variability and lower limb power and aerobic power tests. Data analysis was initially done by checking the normality of the data using the Shapiro-Wilk test. If normality was confirmed, the data were presented by mean and standard deviation and the daily, weekly, and post-competition data were compared by ANOVA for repeated measures, and the correlations between training load indicators and physical performance were tested by Pearson's coefficient. Otherwise, data were presented by median and interquartile range, and daily, weekly, and post-competition data were compared by Friedman's test and correlations were tested by Spearman's coefficient. All analyses were done in SPSS 20.0 software and the alpha value was set at 5%. The main findings suggest that the imposed training loads were not sufficient to induce detectable overreaching or recovery/compensation, at least by the variables used; that training did not promote relevant changes in the aerobic power tested and; that positive correlations were not identified among the variables analyzed. In summary, the training load imposed in the preparation of elite Crossfit® athletes was relatively stable, despite the constant variation of stimuli and settings, and of moderate level. Our findings may help to explain training patterns that involve high volume and frequency of training maintained for long periods, which does not match (at least theoretically) with high intensity efforts.

(Universidade Federal do Pará, 2021-12-07) MORAES, Luana Correa Pardauil de; SILVA, Marília Passos Magno e; http://lattes.cnpq.br/9123524811984821; https://orcid.org/0000-0002-7322-6364
After Paralympic insertion, sitting volleyball experienced a solid development and greater introduction of athletes in the sport, a fact that required a greater increase in intensity and frequency in training and competitions, contributing to increase competitiveness and the occurrence of injuries. The main objective of the present study is to identify the epidemiological aspects of sports injuries in seated volleyball athletes. The systematic review followed the declaration of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and was registered in the International Prospective Register of Systematic Reviews (PROSPERO) platform. The search platforms selected for the research were: PubMed, BVS, SciELO, SPORTDiscus and Medline. The research included studies that presented: data on the profile of sports injuries in seated volleyball athletes; with a sample composed of competitive athletes at least 1 year old and over 18 years old; published between 1980 and 2020; in English, Spanish and Portuguese. Two independent reviewers applied the search strategy and assessed the methodological quality according to the STROBE and STROBE-SIIS statements. Duplicate removal was performed using EndNote software. After collecting eligible studies, data were expressed in tables, charts and a map. Finally, we found in the included studies a clinical incidence of 0.57 and prevalence of 54.1% of injuries, with a predominance of injuries in the upper limbs (53.8%), specifically in the shoulder (28.9%), by overload mechanism (58%), acute (66%), at the time of training (48%), resulting in absence (52%), severe (38%) and non- recurring (57%). Given this epidemiological profile, we suggest guidelines for preventive conduct, training planning and protection of the athlete's health.

Predição da massa livre de gordura e do índice de massa muscular por impedancia bioelétrica em homens com tetraplegia fisicamente ativos
(Universidade Federal do Pará, 2022-05-25) VIEIRA, Andreia Bauermann; KOURY, Josely Correa; http://lattes.cnpq.br/9039270525512042; https://orcid.org/0000-0002-3189-9261; SILVA, Anselmo de Athayde Costa e; http://lattes.cnpq.br/4794918582092514; https://orcid.org/0000-0001-5265-619X
Individuals with cervical spinal cord injury (c-SCI) experience progressive loss of fat-free mass (FFM) due to decreased physical activity and neurological impairments because the function of spinal neuronal circuits below the level of injury is impaired. Therefore, there is a reduction in muscle strength and physical performance, characterizing sarcopenia, similar to what occurs in the elderly. The bioelectrical impedance (BIA) method is valid and accessible for predicting FFM in different population. The ground of the BIA method is based on the principle of constant hydration. However, individuals with c-SCI show important variations in hydration status, a fact that makes it difficult to use generalized predictive equations for FFM by BIA. Considering that the prediction of FFM in individuals with c-SCI is important to monitor changes in body composition and to support studies on sarcopenia, the present dissertation aims to: 1) test the agreement between the FFM values obtained by three different predictive equations by BIA and by dual-energy X-ray absorptiometry (DXA), 2) test the applicability of bioelectrical impedance vector analysis (BIVA) for this group; and 3) compare the use of the muscle mass index (SMI) from the FFM obtained by BIA and DXA for the diagnosis of sarcopenia in people with tetraplegia, considering different levels of physical activity (sedentary, active >150 minutes per week, and very active > 210 minutes per week). Able bodied individuals (n=23) and with c-SCI physically active (n=13) or inactive (n=10) participated in the study. Only the equation by Buchholz et al. showed agreement (coefficient of agreement=0.85) with DXA. Sarcopenia is a common disease after c-SCI and can be diagnosed using the SMI, which was tested in this group using the suggested equations for BIA and DXA. The use of the SMI-BIA to classify sarcopenia in sedentary c-SCI individuals resulted in substantial diagnostic agreement (Kappa=0.727) according to the Kappa coefficient. Buchholz et al. equation presented the best agreement, but this was not enough for this equation to be recommended for use in people with c-SCI and a specific equation for this population should be created. However, the use of cut-off points to diagnose sarcopenia from the SMI-BIA seems promising in sedentary people with c-SCI, necessitating further studies in people with c SCI that are physically active.

Background: Paralympic sport is sport adapted to include people with disabilities. In sports in general, due to the characteristics of the level of performance, health problems are prevalent and urinary incontinence can be one of them. However, there is little epidemiological data in the literature on such alterations in para-athletes. Aim: To verify the prevalence of urinary incontinence symptoms in paralympic athletes. Material and Methods: This was an observational, cross-sectional, quantitative and descriptive epidemiological study of paralympic athletes from all disciplines. Data was collected using an electronic form that included an ICF, sociodemographic data, the International Consultation on Incontinence Questionnaire (ICIQ-UI Short Form) and the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB). Results: The prevalence of urinary incontinence in the sample (n=95) was 47.36%, with moderate severity (40.00%) and an impact on quality of life averaging 7±3

Breast cancer is an aggressive and mutilating disease responsible for the highest number of deaths among women in Brazil. The mastectomy postoperative period leads to limitations of upper limb movement, particularly of ipsilateral side to the affected breast. This research aimed to investigate whether motor representations of upper limb are modulated after mastectomy surgery. For this, a hand laterality judgment experiment was carried out, in which the participant identified whether the images projected on a computer screen represented a right or left hand. Respecting the inclusion criteria, 17 women participated in the study, 9 with mastectomy with some limitations of upper limb movements, ipsilateral to the affected breast and 8 healthy women who underwent the same experiment, at the Laboratory for the Evaluation and Rehabilitation of Cardiovascular Dysfunctions, Oncology and Respiratory - LACOR (UFPA). The results showed a lower accuracy for mastectomized women when assessing the laterality of the ipsilateral hand to the affected breast compared to the control group, particularly for restricted biomechanically postures (i.e., palmar view and 90° lateral orientation). Such results suggest changes in the motor representations of the upper limb ipsilateral to the affected breast.

Responsividade de parâmetros neuromusculares e capacidade funcional a dose mínima de treinamento resistido em mulheres de meia-idade e idosas
(Universidade Federal do Pará, 2023-04-24) NORONHA, Ádria Samara Negrão; COSWIG, Victor Silveira; http://lattes.cnpq.br/0097939661129545; https://orcid.org/0000-0001-5461-7119
Resistance training (RT) is an effective strategy to mitigate the loss of muscle strength and the risk of functional limitations that occur drastically after 55 years of age. However, there is evidence of inter-individual variations in responsiveness to resistance training, since some people can be responsive and others non-responsive to the same protocol. Thus, the objective of the present study was to verify the responsiveness of middle-aged and elderly women submitted to TR with a minimum dose approach and to verify the effect of the protocol on muscle strength and functional capacity of the participants. Twenty-two untrained women, mean age 64.3 ± 7.2 years, body mass 65.5 ± 9.2 kg, and height 152.3 ± 4.3 cm, randomly assigned to the Intervention Group (INT), submitted to the minimum dose protocol during 4 weeks, or to the Control Group (CON), who participated in two lectures and two stretching classes. The participants were evaluated for strength (1 repetition maximum in Leg Press 180º, Seated Rowing, and Straight Supine) and functional capacity (Timed Up and Go, Physical Performance Battery) before and at the end of the 4 weeks. For the statistical analysis it was performed the Analysis of Variance of repeated measures and Bonferroni post-hoc test for data with normal distribution, Mann Whitney U test for non-normally distributed data, Deltas of variation (Δ%) to present percentage of change and independent t test to compare the means of percentage of change between groups. The significance level adopted was p< 0.05. Levene's test was used to check the variance between groups. For classification of responsiveness, the standard deviation of the CON change score was multiplied by 1.96. Individuals outside this range were classified as High responders or Low responders. The results suggest 16.6% High responders in the 1RM of the straight supine and 8.4% in the estimated 1RM in the same exercise, with 25% High responders for average and peak velocity of the Sit and Stand test. Regarding the mean differences, we observed significant increases in muscle strength only for INT, with no differences between groups. Thus, it is concluded that 4 weeks of TR performed with a minimal dose approach presents a small rate of High responders for upper limb strength and lower limb speed. Furthermore, the training dose used seems to be insufficient to generate greater muscle strength and functional capacity adaptations than the control in middle-aged and elderly women.

Sensores inerciais: Uma alternativa objetiva para classificação baseada em evidências do Basquete em cadeira de rodas
(Universidade Federal do Pará, 2021-05-19) SÁ, Karina Santos Guedes de; SILVA, Anselmo de Athayde Costa e; http://lattes.cnpq.br/4794918582092514; https://orcid.org/0000-0001-5265-619X
The classification system for Paralympic sports has evolved with the improvement of evaluations, to make competitions fairer. With this, an international movement was developed to make the classification of athletes based on evidence. Such evidence can be obtained in different ways, such as tests and valid equipment for measures of variables related to classification. Thus, the main objective of this dissertation was to investigate the use of inertial sensors in the sportive classification process of wheelchair basketball. The dissertation was written in the aggregated model of articles and has two articles: a systematic review and an original study. In the systematic review, we observed that instruments such as kinematics, dynamometers and inertial sensors have been applied in the evidence- based classification in wheelchair sports, using variables such as strength, speed and acceleration to discriminate subjects from different classes. In our original study, we observed that: 1) higher class athletes performed performance tests in less time; 2) 16 variables showed moderate and strong significant correlations with the sports class; 3) the variables collected with the sensor positioned in the wheelchair presented a greater number of strong and moderate correlations with the sports class and; 4) the Illinois agility test showed more variables correlated with the sports class when compared to the maximum speed test of 20 meters and the anteroposterior axis of both sensors showed a greater number of variables correlated with the sports class. In summary, the inertial sensors seem suitable for assessing the sporting class. Finally, we believe that the use of technologies in the sports environment will grow more and it seems to be a path of no return, taking performance and competitions to other levels.
