The purpose of this study was to examine whether a high--volume compared to a low--volume whole--body resistance exercise session acutely impairs lung function. Fifteen competitive male bodybuilders (age 27.4 ± 5.4 y; body mass 89.7 ± 12.8 kg; stature 177.9 ± 4.8 cm), in a crossover trial, completed two resistance training protocols (high--volume: 5 sets per exercise; low--volume: 2 sets per exercise) and a control session (no exercise) on 3 separate occasions. The physiological demands of the two resistance exercise sessions were significantly different as indicated by greater VE, VO2, and HR (P<0.05), and lower PETCO2 (P<0.05) responses for the majority of exercises during the high--volume compared to low--volume session. No significant differences were found for lung function measures (FVC, SVC, FEV1, FEV3, FEV6, IC, ERV, and MVV) between pre-- and post--session for the low--volume and high-volume sessions. The findings suggest that the ventilatory muscle demands of a strenuous resistance exercise session are not great enough to acutely affect indices of lung function.
