Respiratory Muscle Strength

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.

This randomized, single-blind, parallel-group controlled trial aims to investigate the effects of expiratory muscle training added to standard pulmonary rehabilitation on respiratory muscle strength, pulmonary function, cough effectiveness, exercise capacity, dyspnea perception, and quality of life in patients with non-cystic fibrosis bronchiectasis. Eligible patients aged 18-70 years with stable disease will be randomly assigned to either a pulmonary rehabilitation-only group or a pulmonary rehabilitation combined with expiratory muscle training group. Outcomes will be assessed at baseline and after completion of the intervention period.

The aim of this study is to investigate the relationship between parity and respiratory muscle strength in women.
