    International Journal of Exercise Science 12(4): 932-940, 2019. The purpose of this study was to compare the effect of 24-, 36-, 48-, 72- and 96-hours between-test rest intervals on the reproducibility of the 10-RM smith machine back squat (BS), bench press (BP) and leg press at 45 degrees (LP45) exercises. Twelve resistance trained men (26.6 ± 4.5 yrs; 179.0 ± 5.5 cm; 92.2 ± 24.6 kg) performed five sets of identical 10-repetition maximum (10-RM) tests for the BS, BP, LP45 exercises, each set with a different interval between tests: 1) twenty-four hours (Post-24), 2) thirty-six hours (Post-36), 3) forty-eight hours (Post-48), 4) seventy-two (Post-72), and 5) ninety-six hours (Post-96). Significant differences in 10-RM from pretest to posttest were observed for BS in Post-24 (p \u3c 0.001; ∆% = -12.62), Post-36 (p \u3c 0.001; ∆% = -6.57), and Post-96 (p = 0.015; ∆% = 6.84). Similarly, significant differences in 10-RM from pretest to posttest were observed for BP in Post-24 (p \u3c 0.001; ∆% = -9.22), Post-36 (p = 0.032; ∆% = -3.04), and Post-96 (p \u3c 0.001; ∆% = 5.37). Finally, significant differences in 10-RM from pretest to posttest were observed for LP45 in Post-24 (p \u3c 0.001; ∆% = -16.55), Post-36 (p = 0.032; ∆% = -5.09), and Post-96 (p \u3c 0.001; ∆% = 5.54). The reproducibility of 10-RM was examined using intraclass correlation coefficients; BS: 0.944, 0.977, 0.988, 0.986, and 0.954 for Post-24, Post-36, Post-48, Post-72, and Post-96, respectively; BP: 0.894, 0.966, 0.966, 0.960, and 0.976; and LP45: 0.832, 0.957, 0.984, 0.974, and 0.977 5. Based on the findings, the optimal between test rest interval duration for 10-RM testing, to provide the best reproducibility, in resistance trained men appears to be 48 to 72 hours for the BS, BP, and LP45 exercises

    International Journal of Exercise Science 12(4): 1346-1354, 2019. The purpose of this study was to investigate the effect of three months of neuromotor fitness on body composition and physical performance in untrained women. Nine untrained women (age: 38.1 ± 6.9 years; total body mass: 79.3 ± 10.7 kg; height: 161.5 ± 3.9 cm; body mass index: 30.4 ± 4.1) participated in the present study. Subjects attended the laboratory on twenty-seven occasions during a three-month period at least forty-eight hours in between sessions. Sessions 1 and 2 were used to measure morphology and body composition, and to familiarize all subjects with the experimental procedure and physical performance tests (muscle power, balance, muscular endurance, and flexibility). During sessions 3 to 26, all exercises were performed twice a week during 60-min in each session. All exercises were divided into three different circuit programs composed by12 stations with one-min exercise and a passive recovery of thirty-sec. There were significant decreases (p \u3c 0.005) for circumference in the right and left arm, pectoral, waist, abdomen, hip, and right and left calf. There were significant increases in lean body mass (p \u3c 0.005) and total body weight (p \u3c 0.005). There were significant decreases for body mass index (p \u3c 0.005), fat mass (p \u3c 0.005), and fat percentage (p \u3c 0.05). There were significant decreases (p \u3c 0.005) for skinfold in triceps, pectoral, subaxilar, shoulder blade, abdomen, hip, and thigh. There were significant increases for power test (p \u3c 0.005), muscular endurance test (p \u3c 0.005), and functional test (p \u3c 0.005). There were no significant differences for flexibility (p \u3c 0.005). The neuromotor fitness program affects the body composition and increases the physical performance in untrained women

    Atualmente presenciamos um aumento na prevalĂȘncia mundial dos transtornos mentais, como ansiedade e a depressĂŁo. A prĂĄtica regular de exercĂ­cio e atividade fĂ­sica sĂŁo importantes intervençÔes para atenuar os sintomas desses transtornos mentais, que devido a pandemia de COVID-19 poderiam aumentar sua incidĂȘncia. O presente estudo teve como objetivo analisar os diferentes nĂ­veis de atividade fĂ­sica e ansiedade dos indivĂ­duos em situação de isolamento social devido a pandemia. Para isso foram aplicados os questionĂĄrios IPAQ e EHAD para analisar os nĂ­veis de atividade fĂ­sica e ansiedade, respectivamente do grupo amostral. Foi encontrado menor prevalĂȘncia de sintomas de ansiedade em indivĂ­duos satisfatoriamente ativos e do sexo masculino, se comparado aos insatisfatoriamente ativos e femininos

    A Educação FĂ­sica Ă© capaz de integrar pessoas, fazendo com que essas pratiquem atividades com igualdade. Com a escola, e, em seu contexto, oferta um espaço privilegiado de construçÔes de significados capazes de discutir a cidadania. O objetivo desse estudo foi analisar a prevalĂȘncia da prĂĄtica de Futebol feminino como atividade extracurricular em escolas da zona sul do municĂ­pio do Rio de Janeiro. Sua realização tem base na pesquisa quantitativa, com coleta de dados por meio de um questionĂĄrio aplicado em 22 (vinte duas) escolas privadas da zona sul do Rio de Janeiro. O estudo apontou um equilĂ­brio nos resultados entre as escolas participantes, em que 53% delas confirmam existir Futebol feminino como atividade extracurricular nas unidades escolares e as demais, em 47% disseram nĂŁo existir. Concluindo, portanto, que ainda hĂĄ escolas que devam implementar o Futebol feminino em suas aulas extracurriculares, visto o direito Ă  igualdade entre meninos e meninas, e, que nĂŁo cabe mais diferenciação de gĂȘnero, neste caso, na prĂĄtica de atividades, inclusive no Futebol

    Introduction: Obesity has been considered an important risk factor for systemic arterial hypertension, while physical activity is seen as a protective agent against this disease. However, in groups of adolescents presenting excessive body weight, there seem to be few investigations focusing on such associations. Objective: To analyze the association between different levels of physical activity on systemic arterial hypertension in a sample composed of overweight and obese adolescents. Methods: The physical activity practices and arterial pressure of 181 overweight and obese adolescents were measured and a Poisson regression model was applied to determine the impact of physical activity on systemic arterial hypertension. Result: There was no association between physical activity practices and arterial hypertension in the sample group investigated (p>0.05). Conclusion: In adolescents with overweight and obese, physical activity was not characterized as being a protective factor in relation to systemic arterial hypertension
