Study population: Adolescent Volleyball Players consist of research group.

Brief summary: A volleyball player with high respiratory muscle endurance can perform at a high level of efficiency during competitions without experiencing fatigue. However, no study has been found in the literature examining respiratory muscle strength, respiratory muscle endurance, cough strength and balance parameters in adolescent volleyball players which was therefore aimed to investigate the potential relationship between these parameters in this study.

Detailed description: Professional sports performance in adolescent volleyball players who have not yet completed their developmental period may be affected in terms of respiratory muscle strength and endurance, cough strength and balance. However, no study has been found in the literature investigating the relationship between respiratory muscle strength, respiratory muscle endurance, cough strength and balance in adolescent volleyball players and these parameters. Therefore, the aim of our study is to determine the relationship between respiratory muscle strength, respiratory muscle endurance, cough strength and balance in adolescent volleyball players.
