[Purpose] In Japan, one measure against the novel coronavirus disease-2019 infection involves the public use of surgical masks. Research indicates that exercising while wearing a mask increases the physical burden, particularly affecting young people during high-intensity exercise. This study examined the effects of wearing masks while running in male university students. [Participants and Methods] The participants were 20 healthy male university students (21.6 ± 1.6 years). The participants underwent cardiopulmonary exercise tests with the masks on and off on different days until exhaustion. The following parameters were measured: exercise duration, Borg Scale rating (respiratory or lower extremities), surface temperature around the mouth, time to sweat onset, metabolic reaction, pulmonary ventilation, and cardiovascular reaction parameters. [Results] The results showed that VO max remained consistent between the mask-on and mask-off conditions. However, minute ventilation, respiratory rate, and heart rate decreased in the mask-on condition, which correlated with a reduction in exercise duration. Furthermore, running with the mask significantly decreased the VE/VO, VE/ VO, Borg Scale rating of the lower extremities, and the time to sweat onset. [Conclusion] Running with a surgical mask affected respiratory function and decreased exercise duration in healthy male university students. However, it did not induce any changes in VO max.
[目的] 在日本，应对新型冠状病毒病2019感染的一项措施是公众佩戴外科口罩。研究表明，戴口罩运动时身体负担会加重，高强度运动时对年轻人影响尤为明显。本研究调查了男大学生跑步时佩戴口罩的影响。[参与者与方法] 参与者为20名健康男大学生（21.6±1.6岁）。参与者在不同日期分别在戴口罩和不戴口罩的情况下进行心肺运动测试，直至力竭。测量以下参数：运动持续时间、Borg量表评分（呼吸或下肢）、口周表面温度、出汗开始时间、代谢反应、肺通气和心血管反应参数。[结果] 结果显示，最大摄氧量在戴口罩和不戴口罩的情况下保持一致。然而，戴口罩时每分通气量、呼吸频率和心率下降，这与运动持续时间缩短相关。此外，戴口罩跑步显著降低了下肢的VE/VO、VE/VO、Borg量表评分以及出汗开始时间。[结论] 戴外科口罩跑步会影响健康男大学生的呼吸功能并缩短运动持续时间。然而，它并未引起最大摄氧量的任何变化。
