Avaliação da sessão de treinamento em atletas paralímpicos de powerlifting de elite baseada em indicadores de força dinâmico e térmicos

Abstract

Background: Paralympic powerlifting is performed on the bench press, aiming to lift as much weight as possible in a single step. Purpose: to evaluate thermal asymmetry and dynamic force parameters with 45 and 80% 1 Maximum Repetition-1RM in PP athletes. Methods: 12 elite PP male athletes were evaluated before and after a training session regarding skin temperature (thermography) and force dynamics indicators (Average Propulsive Velocity-MPV, Maximum Velocity-VMax, and Power). The training consisted of 5 series of 5 repetitions (5X5) with 80%1 RM. The force indicators and dynamics before and after (45%1RM) were evaluated in series “1” and “5” with 80% 1RM. Results: The temperature did not present asymmetry, there were differences between the moment before and after. In MPV, Vmax, and Power, with 45% 1RM, there were differences, both in asymmetry and in moments (p<0.005). With 80% 1RM, asymmetry was observed, but no differences between moments (p<0.005). Conclusion: No thermal asymmetry was observed. There were reductions in MVP and VMax at 45 and 80% 1 RM but without significant differences between time points (before and after). However, there was asymmetry in the moments before and after within a safety standard, where Paralympic powerlifting was safe in terms of asymmetries.
