U.S., Aug. 26 -- ClinicalTrials.gov registry received information related to the study (NCT07784517) titled 'Diaphragmatic Facilitation and Upper Extremity Performance in Volleyball Players' on Aug. 21.

Brief Summary: The diaphragm contributes to both respiration and trunk stabilization. Effective diaphragmatic function may support postural control, force transfer, and upper extremity performance during dynamic activities. However, evidence regarding the immediate effects of manual diaphragmatic facilitation on upper extremity performance in athletes remains limited.

This study aims to investigate the immediate effects of manual diaphragmatic facilitation on upper extremity performance and respiratory function in actively participating vo...
