This study will test the hypothesis that six weeks of inspiratory muscle training (IMT) will increase diaphragm muscle thickness, power, and aerobic exercise performance. Utilizing the K5 PowerBreathe device for IMT, participants will complete a six-week training protocol to assess its impact on peak inspiratory pressure (S-Index) and endurance exercise performance (VO2max). Pre- and post-intervention measurements will include diaphragm thickness assessed via ultrasound, S-Index, peak inspiratory flow (PIF), maximal cycling power output, and VO2 max. VO2 max and maximal cycling power will be determined through a step-ramp-step bike test utilizing pulmonary gas exchange measurements. This investigation explores how IMT influences respiratory muscle function and may enhance athletic performance. The findings are anticipated to contribute to a deeper understanding of cardiorespiratory health and performance enhancement strategies, with potential applications for athlete, operational, and clinical populations.
