BACKGROUND
we aimed to investigate the physiological impact of facemasks use during a graded treadmill exercise test in male adolescents and young adults.
MATERIALS AND METHODS
Twenty-one males aged 15 to 28 volunteered. Participants completed four sessions with a 72-hour gap between each session. They completed four visits: 1 rest and 3 graded treadmill exercise test sessions no mask, surgical mask, and FFP2/N95 mask. Pre- and post-graded treadmill exercise test, heart rate, systolic blood pressure, diastolic blood pressure, and blood oxygen saturation were measured. Repeated measures analysis of variance determined statistical differences (p<0.05).
RESULTS
There were no differences in exercise performance (e.g., time to termination, estimated VO2max) nor heart rate, systolic blood pressure, and diastolic blood pressure between conditions. FFP2/N95 mask resulted in lower blood oxygen saturation compared to no mask and surgical mask, and the surgical mask was lower than no mask at exhaustion.
CONCLUSION
Participants could safely complete the graded treadmill exercise test without detriment to exercise performance even though blood oxygen saturation decreased with facemask use.
背景
我们旨在研究男性青少年和年轻人在分级跑步机运动试验期间使用口罩的生理影响。
材料与方法
21名年龄在15至28岁之间的男性自愿参与。参与者完成了四个阶段，每个阶段之间间隔72小时。他们进行了四次访视：1次休息和3次分级跑步机运动试验，分别不戴口罩、戴外科口罩和戴FFP2/N95口罩。在分级跑步机运动试验前后，测量心率、收缩压、舒张压和血氧饱和度。重复测量方差分析确定统计学差异（p<0.05）。
结果
不同条件下的运动表现（如终止时间、估计的最大摄氧量）、心率、收缩压和舒张压均无差异。与不戴口罩和戴外科口罩相比，戴FFP2/N95口罩导致血氧饱和度降低，且在运动疲劳时，戴外科口罩的血氧饱和度低于不戴口罩的情况。
结论
尽管使用口罩会导致血氧饱和度下降，但参与者仍可安全地完成分级跑步机运动试验，且不会损害运动表现。
