PurposeTo investigate the patterns of recovery of ball possession in a young futsal team.MethodsSeven games played by a youth futsal team were analysed. Patterns of recovery of ball possession were investigated on the basis of the following variables: way to recover the ball, location of recovery, tactical behaviour after the recovery, and result of the match. One-way ANOVA and post-hoc Tukey honest significant difference test were used to compare the variables. Principal component analysis was also applied to verify the association between variables.ResultsIt was observed that there was a greater number of ball recoveries in the defensive sector (F_3,24 = 35.6; <i>p</i> < 0.001; η_p² = 0.79), that set pieces were the most frequent way to recover the ball (F_5,36 = 7.9; <i>p</i> < 0.001; η_p² = 0.46), that ball possession was maintained more often after the recovery of the ball (F_3,24 = 79.6; <i>p</i> < 0.001; η_p² = 0.90), and that there was no correlation between the result of the match and the number of ball recoveries (F_3,24 = 0.20; <i>p</i> = 0.93; η_p² = 0.10). Four components were identified that represented a variance of 95% for all variables. Factor 1 was related to the patterns of ball possession recovery in the offensive sector, while factor 2 was related to the tackle.ConclusionsIt was concluded that the way to recover the ball and the location of recovery affected both patterns of recovery and tactical behaviour after the recovery of the ball.

Introduction: During the aging process, significant changes in the pattern of distribution of morphological and structural variables such as body fat and muscle mass can be observed. Objective: To analyze the distribution of total and appendicular muscle mass in women in different age groups. Methods: The sample consisted of 129 women, aged between 50 and 80 years. The study was divided into two stages, composed of the anthropometric measures, total body mass (kg) and height (m) and body composition evaluation using DEXA. Results: There was a significant reduction in muscle mass with the advancement of age, and from age 60 and older, the age group showed a significant increase when compared to subjects of lower age, with a decrease of 1.65 kg in their total muscle mass. It should be noted that in our study, this progression increased in subjects older than 72 years, with a decrease of 2,10 kg in their total muscle mass. Conclusions: The reductions of muscle mass in the lower limbs presented greater amplitudes in comparison with the other regions of the analyzed human body, being an area with greater focus of analyzes with the objective of identifying and assisting the diagnosis of sarcopenia in future studies.
