INFLUÊNCIA DO TREINAMENTO COM INSTABILIDADE SOBRE O EQUILÍBRIO E A COORDENAÇÃO NOS JOGADORES DE TÊNIS

Abstract

ABSTRACT Introduction: Corporal balance and psychomotor coordination are factors of extreme importance in the physical fitness of tennis players. It is believed that implementing training with instability in training can have repercussions in a better capacity of action influencing positively in the sports practice. Objective: Explore whether the addition of instability training to daily training can influence the physical fitness of tennis players. Methods: For this experiment, 100 national secondary professional tennis players were selected as volunteers, and divided equally into experimental and control groups. The experimental group received 12 weeks of additional intervention with instability training, while the control group remained with standard training. Pertinent data were collected before and after the intervention, statistically analyzed, and compared to the literature. Results: Anterior motion range of motion in the experimental group increased from 28.965 ± 0.418 to 39.357 ± 0.25; anterior motion accuracy increased from 26.258 ± 2.239 to 34.608 ± 0.342. Posterior stroke range of motion increased from 25.026 ± 2.136 to 34.528 ± 0.10, and posterior motion accuracy increased from 18.230 ± 1.096 to 28.225 ± 0.261. The data in the control group did not show significant changes. Conclusion: Instability training added to tennis players’ daily training may influence tennis players’ balance ability and movement coordination, positively impacting tennis players’ fitness.
