Wearable Resistance Vest for Strengthening Respiratory Muscles

Brief Summary

Respiratory muscle weakness significantly limits functional capacity in various populations, yet conventional respiratory muscle training (RMT) often requires coached, mouthpiece-based maneuvers that may be limited by technique and adherence. This proof-of-concept study evaluated the physiological efficacy of a novel, low-cost wearable resistance vest designed to provide continuous circumferential thoracic loading during spontaneous breathing to improve respiratory muscle strength in healthy adult males.
