The study found that wearing a cloth face mask increased respiratory muscle effort, decreased ventilatory volume, and slightly reduced exercise tolerance. However, there was no significant impact on peak oxygen uptake.
We aimed to determine the effects of wearing a cloth face mask on cardiorespiratory response, peak oxygen uptake (Vo(2)), respiratory muscle effort, and exercise tolerance during incremental exercise. The study had a randomized crossover design: 11 apparently healthy young men performed the Bruce protocol treadmill test in two conditions, wearing a cloth face mask (CFM) and without CFM (CON), in random order. Minute ventilation and oxygen uptake were measured using a mass spectrometry metabolic analyzer; cardiac output (CO) was measured using an impedance CO monitor; and mouth pressure (P-m) was measured and calculated as an integral P-m to assess respiratory muscle effort. Maximal minute ventilation was 13.4 +/- 10.7% lower in the CFM condition than in the CON condition (P < 0.001). The peak Vo(2) (52.4 +/- 5.6 and 55.0 +/- 5.1 mL/kg/min in CFM and CON, respectively) and CO were not significantly different between the two conditions. However, the integral value of P-m was significantly higher (P = 0.02), and the running time to exhaustion was 2.6 +/- 3.2% lower (P = 0.02) in the CFM condition than in the CON condition. Our results suggest that wearing a cloth face mask increased respiratory muscle effort and decreased ventilatory volume in healthy young men; however, Vo(2) remained unchanged. Exercise tolerance also decreased slightly.
