Effect of detraining on anthopometric characteristics and physical performance in Under-17 Futsal players
Abstract
Objective. This study evaluated the effect of 8 weeks of detraining on anthopometric characteristics and physical performance in Under-17 Futsal players. Material and method. Sixteen Under-17 male Futsal players from Marcos Olsen Team (Caçador, Brazil) participated in the study. The evaluations happened in the final competitive period of 2016, and the last week of January 2017, totaling eight weeks of detraining. Total body mass, stature, body span and body mass index (BMC) were evaluated. In physical performance, agility, speed, upper and lower limb explosive strength, localized muscular resistance, flexibility and cardiorespiratory fitness were evaluated. Results. After a period of 8 weeks of detraining the total body mass increased 2.5%, stature 1.2% and body span 1.4% in Futsal players (p<0.05). Detraining decreased the players' physical performance in agility and speed increasing the test time by 17.9% and 18.8%, respectively, (p<0.01). Decreased upper and lower limb explosive strength by 16.7% and 5%, respectively, (p<0.01). Localized muscle resistance and flexibility decreased by 8.5% and 9.6%, respectively, (p<0.01). Cardiorespiratory fitness was also reduced by 5.4% after the detraining period (p<0.001). Conclusion. An period of eight week detraining changes anthropometric characteristics and decreases physical performance in Under-17 Futsal players.
