Comparison of elbow flexor isokinetic peak torque and fatigue index between men and women of different training level

The purpose of the study was to compare elbow flexion peak torque (PT) and fatigue index (FI) during isokinetic concentric contractions in men and women with different training levels. Sixty-eight young men and women were divided into four groups: resistance trained men (RTM), non-resistance trained men (NRTM), resistance trained women (RTW) and non- resistance trained women (NRTW). Participants performed two tests on an isokinetic dynamometer, one to evaluate PT and one to evaluate FI. Significant interactions were found for sex and resistance training status with both PT and FI. In general, resistance-trained subjects had higher PT, and women showed lower PT than men. PT values were 67.12 ± 9.93 N·m for RTM, 49.9 ± 8.5 N·m for NRTM, 41.84 ± 7.52 N·m for RTW, and 26.05 ± 3.34 N·m for NRTW. Separate analysis revealed that RTM had higher PT than all other groups. However, FI was higher for NRTM than for RTM and NRTW and no difference was found between RTM and NRTW. FI was 37.86 ± 10.89 % for RTW, 45.74 ± 13.17 % for NTRW, 45.89 ± 8.24 % for RTM, and 51.92 ± 4.5 % for NRTM. Women produce lower PT, and have a higher fatigue tolerance than men of similar training status. Considering that women showed to be more resistant to fatigue than men, women can manipulate training variables differently from men, such as, including more repetitions at the same relative load or using higher relative loads at the same number of repetitions.

High-level female volleyball: analysis of the attack on Superleague Female

The objective of this study was to analyze the relationship between tempo and type of attack with the effect of the attack on Women Superleague (Brazilian Championship). For such, we resorted to the analysis and observation of 11 games, earning a total of 1831 actions of attack. The variables investigated were the type of attack realized, the tempo of attack and the effect of the attack. The appreciation of inferential analysis of collected data allowed, through the qui-square analysis, established that there was a statistically significant association between the type of attack and the attack effect (X2 = 577.967, p = 0.000) and between the tempo of attack and the attack effect (X2 = 26.606, p = 0.003). The association between the type of attack and the effect of the attack has shown that the attack on the diagonal was the most frequent and put the attack allowed to occur more than expected continuity of the game. In relation to tempo of attack was observed that despite the attack 3rd time have been the most recurrent, was associated with the point of attack 1st time. Thus, this study concluded that, for the population tested, the potent attack showed to be most frequent. Furthermore, it was observed that there was a predominance of slower game (3rd time), favoring the continuity of the game, therefore, when the game was made with more speed there is the increased chance of success in the attack.
