The Effects of Interval Respiratory Muscle Training on Athletic Performance
Sponsor: Ondokuz Mayıs University
Summary
This study evaluated the effects of a 4-week respiratory muscle training (RMT) program using constant versus incremental threshold resistance on respiratory muscle strength, pulmonary function, extremity strength, and aerobic/anaerobic endurance in trained athletes. Participants were randomized into two groups: the Constant IMT group (trained at a fixed 40% of maximal inspiratory pressure \[MIP\]) and the Incremental IMT group (progressing weekly from 50% to 80% of MIP). Both groups trained twice daily, 5 days per week (2 sets of 30 breaths/day) for 4 weeks. Standardized physiological, spirometric, and athletic performance tests were assessed at baseline and post-intervention.

Interventions
IMT %40 MIP
This study examined two inspiratory muscle training (IMT) protocols using the PowerBreathe device. Participants in both groups performed IMT twice daily, five days a week, for four weeks. Each session included 30 inspiratory breaths, totaling 60 breaths per day. The Constant IMT group trained with a fixed resistance of 40% MIP throughout the intervention. All participants received supervised instruction during the initial session. Subsequent sessions were home-based, monitored weekly through video submissions and participant check-ins. This design enables a structured comparison between progressive and constant loading in IMT for improving respiratory strength and endurance in trained athletes.
IMT %50-60-70-80
This study examined two inspiratory muscle training (IMT) protocols using the PowerBreathe device. Participants in both groups performed IMT twice daily, five days a week, for four weeks. Each session included 30 inspiratory breaths, totaling 60 breaths per day. The Incremental IMT group began training at 50% of Maximal Inspiratory Pressure (MIP), with resistance increased weekly to 60%, 70%, and 80%. All participants received supervised instruction during the initial session. Subsequent sessions were home-based, monitored weekly through video submissions and participant check-ins. This design enables a structured comparison between progressive and constant loading in IMT for improving respiratory strength and endurance in trained athletes.
