Abstract
OBJECTIVE The objective of this study was to evaluate the effects of 12 weeks of resistance training (RT) with progressive intensity on factors associated with sarcopenia in older individuals. METHODS A cross-sectional study was conducted with 74 participants (64.27 ± 7.06-y-old) who were divided into a control group (n = 37) and an intervention group (n = 37). The intervention group underwent 12 weeks of RT three times a week, with an initial training of 60% and final training of 85% of one-repetition maximum (1RM). Both groups were evaluated before and after the 12-week training period to assess improvements in strength and physical performance. RESULTS The intervention group showed an increase in physical performance, as evidenced by a reduction in the time to perform the Timed Up and Go (TUG) test (p < 0.01) and the Five Times Sit to Stand Test (p < 0.01). Furthermore, the RT proved to be efficient for increasing hand grip and overall muscular strength, as confirmed through the 1RM test. However, the muscle mass index (MMI) and walking speed did not show any significant alterations in both groups. CONCLUSIONS In conclusion, 12 weeks of RT with progressive intensity has a positive effect on the diagnostic parameters of sarcopenia, leading to improvements in physical performance and muscular strength while maintaining the MMI.

Abstract
Introdução: A sarcopenia é considerada uma patologia caracterizada pela redução da massa muscular esquelética e da sua funcionalidade, sendo que vários dos parâmetros que influenciam sobre a sarcopenia sofrem interferência do treinamento de força. Objetivo: Revisar os efeitos dos diferentes protocolos de treinamento de força (frequência, duração e intensidade) sobre parâmetros influenciadores da sarcopenia. Métodos: Trata-se de uma revisão sistemática de estudos originais, quantitativos, observacionais, publicados entre 2010 a 2020, em inglês, espanhol e português, e indexados nas bases de dados SciELO, PubMed e periódico CAPES. Os descritores utilizados foram: “força muscular” (“muscle strenght”, “fuerza muscular”), “sarcopenia” (“sarcopenia”), “envelhecimento” (“aging”, “envejecimiento”), “idosos” (“olders, “ancianos”), “treinamento de força/resistência” (“strength training”, “entrenamiento de fuerza”). Foram recuperados 215 artigos, entre eles 11 atenderam aos critérios de inclusão, sendo incluídos na revisão. Resultados: Dentre os 11 estudos analisados, observa-se que o treinamento de força aplicado em diferentes protocolos foi eficiente em aperfeiçoar parâmetros como massa e força musculares, equilíbrio corporal e desempenho em testes diagnósticos de sarcopenia. Conclusão: Esta revisão evidencia os benefícios da prática de exercício de força em diferentes protocolos sobre parâmetros que influenciam na instalação do quadro de sarcopenia em idosos. O exercício de força se apresenta como meio aplicável, prático e não farmacológico da prevenção de sarcopenia.

Effects of myofascial release of the ankle plantar flexors on static postural balance of young men: A randomized clinical trial. J Bodyw Mov Ther 2021; 28:121-125.

Abstract
BACKGROUND Myofascial release (MR) has been widely used in sports and clinical environment. There are studies that have already evaluated the effect of MR on postural control, however, the data found are inconclusive. OBJECTIVES Investigate the effect of MR on ankle plantar flexor muscles over static postural balance. METHOD Sixty-five young men were randomized allocated into one of three groups: 1) MR group (n = 25, Myofascial Release); 2) Sham (n = 25, fake intervention); or 3) Control group (n = 15). Both MR and Sham techniques were applied during 5 min in the ankle flexors of each leg. The bipodal static postural balance test was performed before and 2 min post each intervention on a force plate with eyes closed during the test. All subjects performed 3 sets of 30-s with 1 min of rest. Mean values to the center of pressure velocity (COPvel) was used for analysis. RESULTS The bipodal balance test showed that there was no significant difference between groups (p > 0.05), but there was a significant time effect (p < 0.05). A significant decrease (p < 0.05) in post-test COPvel (cm.s-1) values (sham 4.9 ± 1.2; MR 4.5 ± 0.6; CON 4.22 ± 0.8) was found when compared to values of pre-test (sham 5.3 ± 1.0; MR 5.0 ± 0.8; CON 4.94 ± 1.3) for all groups. CONCLUSIONS The results demonstrated that MR performed on ankle flexors did not affect static postural balance in young man. This study is a clinical trial (Register Number: RBR-48k5jm).

Abstract
Abstract This study aimed to evaluate the effects of cumulative school soccer matches separated by 24-h or 48-h intervals on the recovery status of U-19 players. Thirty-four school athletes (17.6 ± 1.1 years) who played in an U-19 school soccer competition (composed of one group with four teams and another group with three teams, followed by semifinals and final) were examined before three matches, which lasted 70 min. Seventeen athletes had a 24-h rest interval between each match (GGG group), while 18 athletes had a 48-h rest interval between the second and third matches (GG48hG group). Total Quality Recovery, countermovement jump, 10-m sprint, and maximum lumbar isometric strength were measured. The internal load of each match was calculated by the product of the session Rating of Perceived Exertion and match time. There was a 22% reduction in Total Quality Recovery (p< 0.001) and 12% in 10-m sprint performance (p< 0.001) before the third match in the GGG group, while the GG48hG group showed no changes for the same variables (p> 0.05). The countermovement jump decreased before the second match in both groups (GGG= 12% and GG48hG= 10%; p< 0.001), with no difference between groups (p> 0.05). In addition, both groups showed no changes in the isometric strength or the internal load match over the games (p> 0.05). Despite not providing complete muscle recovery, a 48-h interval between the second and third matches seems to have minimized the reduction of muscle performance due to consecutive matches.

Abstract
Resumo Objetivo: verificar o efeito do esforço físico sobre as funções cognitivas de trabalhadores eletricistas utilizando equipamento de proteção individual (EPI). Métodos: participaram 28 eletricistas que trabalhavam na construção, manutenção e operação de redes de distribuição de energia. Todos do sexo masculino, sadios e aptos para a prática de exercícios físicos. As funções cognitivas foram representadas pelo teste de reação simples (TRS) e pelo nível de vigilância mental (NVM). O TRS e o NVM foram mensurados pré e pós-teste máximo progressivo, em esteira rolante, a 27 °C de temperatura seca e umidade relativa do ar de 64%. O teste consistiu em aumentos progressivos na velocidade e na inclinação da esteira até a fadiga, com utilização de EPI. Resultados: a média (desvio padrão) do TRS não foi significativamente diferente antes, 227,8 (35,1) ms, e após o exercício, 220,6 (24,6) ms. O NVM foi significativamente maior após o exercício em todas as situações: frequência crescente - 36,5 (5,1) Hz vs 39,5 (2,7) Hz, frequência decrescente - 36,0 (5,2) vs 39,0 (3,88) Hz, e frequência geral - 36,2 (4,9) vs 39,2 (3,1) Hz. Conclusão: o exercício progressivo máximo realizado com EPI não modificou o tempo de reação simples e aumentou o nível de vigilância mental de eletricistas.
