Key result
Participation in an endurance triathlon caused significant declines in FVC (7.1%), FEV1 (8.4%), FEF25-75% (15.2%), FEF50% (18.6%), and inspiratory muscle strength (up to 26%).

Does an endurance triathlon reduce pulmonary function and respiratory muscle strength in male competitors?
Participation in an endurance triathlon leads to transient declines in vital capacity, mid-lung volume flow rates, and inspiratory muscle strength.
Hill et al. (1991) reported an observational. Endurance triathlon vs. Baseline (pre-event) was evaluated on Forced expiratory spirogram, indices of inspiratory and expiratory muscle strength, and maximal voluntary ventilation. Participation in an endurance triathlon caused significant declines in FVC (7.1%), FEV1 (8.4%), FEF25-75% (15.2%), FEF50% (18.6%), and inspiratory muscle strength (up to 26%).
