(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.

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.

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.

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.

Treinamento resistido de dose mínima aumenta força sem alterar a modulação autonômica cardíaca, função hemodinâmica e capacidade funcional de mulheres menopáusicas: um ensaio clínico randomizado
(Universidade Federal do Pará, 2023-04-28) DIAS, Rayra Khalinka Neves; COSWIG, Victor Silveira; http://lattes.cnpq.br/0097939661129545; https://orcid.org/0000-0001-5461-7119
Menopausal women have disorders in cardiac autonomic control that add to other deleterious effects such as functional and muscle decline. The aim of this study is to investigate the effects of minimal dose resistance training (RT) on cardiac autonomic modulation, hemodynamic parameters, strength and functional capacity in menopausal women. This study is a randomized clinical trial, submitted to the Brazilian Registry of Clinical Trials under the code RBR-2p4gpvk and approved by the Research Ethics Committee of the Institute of Health Sciences, Federal University of Pará (CEP–ICS/UFPA), under the opinion number 4,922,776/2021. The present investigation analyzed 29 women who were randomized to the training group (TG: 63,1±9,0 years) and control group (CG: 59,6±7,4 years). The TG performed the minimum dose RT twice a week for a period of four weeks. Assessments were performed before and after the protocol period, with anthropometric measurements, hemodynamic parameters (heart rate and blood pressure), autonomic modulation (RMSSD, SDNN, PNN50, HF, LF, LF/HF), functional capacity (6 min walk test and Short Physical Performance Battery), and strength with the test of 1 repetition maximum (1 RM). Two-way ANOVA (group*time) was performed with repeated measures with bonferroni post-hoc test and significance level p< 0.05. The results revealed that there was a group*moment interaction only in the autonomic index LnRMSSD (F= 1,01; ω 2= 0,055; p= 0,02), but the analysis of the main effects did not reveal differences between groups (d= 0.10; p= 0.70) and moments (d= 0.13; p=0.64). In addition, there was a significant interaction for the 1 RM bench press test (F= 10.30; ω2= 0.014; p< 0.01), but with no main group effect (d= 0.18; p= 0.62 ) and with moment main effect (d= 0.23; p< 0.01). In comparisons between moments, with significant improvements in the 1 RM seated row (F= 11,64; ω 2= 0,059; p< 0,01), 1RM bench press (F= 8,73; ω 2= 0,011; p< 0,01), 1 RM leg press (F= 19,77; ω 2= 0,095; p< 0,01). In this sense, minimal dose RT showed benefits in muscle strength, but it was not enough to produce autonomic, hemodynamic and functional adaptations in menopausal women.
