Respiratory Function and Athletic Performance in Professional Soccer Players
Sponsor: Istinye University
Summary
This prospective observational study aims to investigate the relationship between respiratory function and multidimensional athletic performance parameters in professional soccer players. The primary hypothesis of the study is that soccer players with enhanced respiratory function and superior respiratory muscle strength will exhibit optimized motor performance outcomes and shorter (faster) reactive reaction times. Investigators will evaluate respiratory muscle strength, spirometric pulmonary functions, dynamic balance, core and abdominal endurance, and reactive visuomotor reaction times during a single testing session within the competitive season.

Interventions
Respiratory and Athletic Performance Assessments
Participants will not receive any experimental clinical intervention as part of this observational study. Instead, they will undergo standard, non-invasive physiological and athletic performance screenings during their competitive season. These assessments will include digital respiratory pressure manometry to evaluate maximal inspiratory and expiratory pressures, computerized spirometry to measure pulmonary functions, the Y-Balance Test for dynamic postural stability, the BlazePod wireless LED system for reactive visuomotor reaction times, and sport-specific field tests (isometric plank, 60-second sit-up, and T-drill agility tests) to evaluate core endurance and agility. All measurements will be completed during a single testing session following standardized recovery intervals.
