AQUATIC RESISTANCE TRAINING REPERCUSSIONS ON THE DYNAMIC STABILITY IN VOLLEYBALL ATHLETES

ABSTRACT Introduction Resistance training is considered a practical pathway for increasing strength and speed. Objective Explore the aquatic resistance training on the dynamic stability in volleyball athletes. Methods Using aquatic resistance training reinforcement, 20 first-level national male volleyball athletes were randomly divided into control and experimental groups. The time of the experiment was ten weeks. In the end, lower limb muscle strength, jumping ability, dynamic stability, and muscle pain were compared. Residual effects were also checked six weeks after the end of the experiment. Results The aquatic resistance training group stopped training for six weeks, peak torque at 60°/s, 180°s of relative knee extension, jump height, full arm swing, and all three phases of the high jump were significantly better than the preliminary test; water entry speed in the vertical direction was also significantly better one week after training. Conclusion Aquatic resistance training can significantly improve the dynamic stability of the lower limbs, and its effect can be maintained up to 6 weeks after completion. It is recommended to apply resistance enhancement training to maintain fitness, especially for long periods.
