The Effect of Preventive Exercises According to Certain Biomechanical Indicators on the Muscular Balance of the Ankle Joint in Young Volleyball Players

Abstract

The research aimed to develop preventive exercises and identify their impact on certain biomechanical and physical indicators, and their relationship to the muscular balance of the ankle joint among young volleyball players. The researcher employed an experimental approach using a single-group design (pre-and post-test). The sample consisted of (8) young players from Al-Hashimiya Sports Club for the (2025-2026) season, selected purposefully. The program included preventive exercises (static, dynamic, and skill-based) conducted over (8) weeks with (3) sessions per week. Biomechanical angles were extracted using (Tracker) motion analysis software, muscular strength was measured via a dynamometer, and dynamic balance was assessed through the (Y-Balance Test). Statistical results (via SPSS) revealed significant differences (sig < 0.05) between the pre-and post-tests in favor of the post-tests regarding dorsiflexion, plantarflexion, and inversion angles, as well as the strength of the dorsal and plantar flexor muscles, alongside a marked improvement in dynamic balance for both legs. The researcher concluded that the proposed preventive exercises effectively enhanced the joint's functional stability and increased muscular balance, thereby improving performance efficiency and reducing the risk of common volleyball injuries.
