Brief Summary:
There is concern that wearing a face mask during COVID will affect oxygen uptake, especially during intense exercise. This study will assess the effect of wearing two different face masks (disposable and cloth) on blood and muscle oxygenation during cycling exercise.

Condition or disease Intervention/treatment Phase
Hypoxemia Other: Progressive cycling exercise test to exhaustion Not Applicable

Detailed Description:
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 two different types of commonly-worn face masks (diposable and cloth) during exercise on blood and muscle oxygenation. Twelve participants who are experienced with cycling will take part in this randomized cross-over study that will assess blood oxygenation (i.e. pulse oximetry) and muscle oxygenation (with near infrared spectroscopy) during a progressive step exercise test to exhaustion. The conditions include no mask, a disposable mask, and a cloth mask. Outcome variables include exercise duration, rating of perceived exertion, blood oxygen saturation levels, and oxygenated, deoxygenated, and total hemoglobin at the quadriceps muscle.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Time to exhaustion during exercise [ Time Frame: Up to 20 minutes ]
    time to exhaustion

  2. Change from baseline in peak power output [ Time Frame: Up to 20 minutes ]
    Peak power output in Watts, determined on a cycle ergometer


Secondary Outcome Measures :
  1. Change from baseline in blood oxygen saturation [ Time Frame: Up to 20 minutes ]
    Blood oxygen saturation as determined by pulse oximetry

  2. Change from baseline in quadriceps tissue oxygenation index [ Time Frame: Up to 20 minutes ]
    Tissue oxygenation index (oxygenated hemoglobin/total hemoglobin) as measured by near infra-red spectroscopy

  3. Change from baseline in rating of perceived exertion [ Time Frame: Up to 20 minutes ]
    Rating of perceived exertion on a scale of 1-10 (Modified Borg Scale), a higher score indicates a greater perceived exertion

  4. Change from baseline in heart rate [ Time Frame: Up to 20 minutes ]
    Heart rate (beats per minute)
