Description

This study investigates the physiological and performance impacts of individualized ventilatory strategies and respiratory muscle training (RMT) in trained endurance athletes. Combining experimental data with a comprehensive review of the literature, the article demonstrates that personalized modulation of respiratory frequency (Rf), tidal volume (Tv), and minute ventilation (VE) significantly improves ventilatory efficiency, oxygen extraction, and mechanical power output. Performance gains were observed at VT₁ (+10.2%), VT₂ (+9.7%), and VO₂max (+5.6%), with cumulative improvements exceeding 20 W at maximal aerobic intensity. Mechanistic adaptations included reductions in the energetic cost of ventilation, enhanced alveolar oxygen extraction (Bohr/Haldane effect), and attenuation of the respiratory metaboreflex. The study also highlights the risks associated with unsupervised ventilatory manipulation, presenting a case study where non-individualized strategies led to CO₂ accumulation, premature acidification, and early termination of high-intensity exercise. These findings position ventilatory strategies as an underexploited but highly promising ergogenic tool, and outline practical guidelines alongside research directions for optimized implementation in sports performance.
