Impact of plyometric training on seasand and physicalqualities of etoile du Congo handball playersduring the 2022-2023 national championship

Objective: The aim of this study was to evaluate the maximal power of the lower limbs during plyometric training in a sandy environment. Methodology: Our study was experimental. It involved 10 elite handball players from the Etoile du Congo team. Anthropometric measurements and two physical tests were measured before and after. However, the jump versus movement jump (CMJ) tests were measured using the Myotest, the speed sprint test over 5, 10, 20 and 30 meters and the repeated sprint test with a two-minute recovery between series. Results: The results obtained showed a significant stabilization of weight and body mass index, and an increase in counter-movement jumping with the arms (p=0.20) and leg power in counter-movement jumping (p=0.57). However, reaction speed at different distances decreased very significantly and there was a significant increase in the counter-movement jump with the arm (p=0.20) and leg power in the counter-movement jump (p=0.57). However, reaction speed at the different distances decreased very significantly. However, there was only a significant increase at SR. Conclusion: Plyometric training improves the explosiveness of handball players' lower limbs. Indeed, this study integrates the current logic of handball intermittence. It can serve as a guide for optimizing performance in intermittent sports such as basketball.
