This study was conducted on twenty-four apparently healthy male individuals (25.50 ± 3.72 years and 76.50 ± 4.50 kg) experienced in strength training. The volunteers performed a 1RM test to determine the training load for the study. Blood pressure and Rate Pressure Product were measured before and at the end of the exercise training. The only significant difference observed was in SBP during strength training at 70% intensity (121.7 ± 8.68, p = 0.039), which was lower than SBP at the remaining intensities of 80% (126.3 ± 7.11) and 90% (127.1 ± 7.51). It was concluded that strength training performed at different intensities and recovery intervals did not significantly alter most variables, changing only the SBP due to the intensity employed.展开更多

Twenty five adolescent males (14.3 ± 0.45 years) participated in the study and were divided into two groups: soccer players (SP – n = 13, 14.1 ± 0.3 years, 58.9 ± 6.90 kg, 1.72 ± 0.04 m, 19.9 ± 1.7 kg·m2, 13.3% ± 4.3% fat) and non-athletes (NA – n = 12, 14.5 ± 0.5 years, 57.3 ± 6.9 kg, 1,67 ± 0.06 m, 20.6 ± 3.9 kg·m2, 14.0% ± 5.7% fat). The square test and 20 m speed test were used to assess agility and speed, respectively. The Tanner self-assessment of pubic hair and genitalia development test was used to estimate maturational development. The Shapiro Wilk test was used to verify the normality of samples. For any data not normally distributed, the non-parametric Mann Whitney test, as well as Kendall’s Tau correlation test, were used. The p-values determined for agility (p = 0.017) and speed (p = 0.054) indicated that agility was the only variable significantly different between SP and NA. The SP and NA groups showed no difference in the levels of maturation (p = 0.41), and maturational status was not significantly correlated with agility (r = 0.013) or speed (r = ?0.003). Conclusion: Individuals who practiced football had better results for the agility test than non-athletes, even with no difference between the degree of maturation and speed. There is a low correlation between level of maturity and agility or speed.展开更多
