简要总结
There is concern that wearing a face mask during COVID will affect oxygen uptake, especially during intense exercise. COVID transmission is especially prevalent in sports such as hockey, where there is close contact between players and arena ventilation is poor. This study will assess the effect of wearing a surgical face mask on simulated hockey performance and blood and muscle oxygenation during cycling exercise.
详细描述
The sport of ice hockey involves close contact between players in poorly ventilated arenas. This increases susceptibility for transmission of viruses, such as COVID-19. Face masks can reduce the risk of virus transmission; however, there is concern that wearing a face mask during exercise will reduce oxygen uptake or increase carbon dioxide re-breathing, which can result in low blood oxygen levels, reduced oxygen delivery to muscle and reduced exercise capacity. The purpose of the study is to determine the effect of wearing a surgical face mask during exercise that simulates ice hockey play on exercise performance and blood and muscle oxygenation in boys and girls. Twelve boys and twelve girls (age 9-14y) who are experienced playing hockey, will take part in this randomized cross-over study that will assess exercise performance, blood oxygenation (i.e. pulse oximetry) and muscle oxygenation (with near infrared spectroscopy) during an exercise test on a cycle ergometer with workloads and work to rest intervals that simulates hockey performance. Participants will also be tested for repeated-sprint performance on ice while wearing full hockey equipment. The conditions include no mask (a "sham" mask) and a surgical mask. Outcome variables include power output during the cycle ergometer testing, skating distance during the on-ice test, rating of perceived exertion, blood oxygen saturation levels, and oxygenated, deoxygenated, and total hemoglobin at the quadriceps muscle.

盲法说明
The participant will be blinded by wearing a sham mask during the "no mask" condition (i.e. they will wear a surgical mask with the covering for the mouth and nose cut out). The individual who will statistically analyze the data will be blinded to conditions
