Sponsor's own description
This study aims to examine how trunk (core) muscle endurance and flexibility relate to athletic performance in elite adolescent tennis players aged 11-18 years. Tennis requires speed, balance, strength, coordination, and repeated high-intensity movements. The trunk region plays an important role in transferring force between the upper and lower body and in maintaining posture and stability during sports activities. However, there is limited research on how trunk physical characteristics influence performance in young elite tennis players. Participants who actively compete in tennis tournaments and train regularly will complete a set of standardized tests assessing flexibility, trunk muscle endurance, balance, sprint speed, agility, and strength. The results will help researchers understand whether trunk flexibility and endurance are associated with better athletic performance. Findings may guide coaches and health professionals in designing training programs that improve performance and potentially reduce injury risk in young athletes.
