Brief Summary:
Face masks are important for prevention of transmission and contracting viruses such as COVID-19. Gymnasiums have been identified as being susceptible to virus transmission; therefore, wearing face masks during exercise is important during pandemics. This study will evaluate performance and physiological stress during high-intensity exercise while wearing a face mask during Crossfit exercise training.

Detailed Description:
Face masks are important for prevention of transmission and contracting viruses such as COVID-19. Gymnasiums have been identified as being susceptible to virus transmission; therefore, wearing face masks during exercise is important during pandemics. This study will evaluate performance and physiological stress during high-intensity exercise while wearing a face mask during Crossfit exercise training. Twenty-four men and women will be randomly assigned to perform exercise during Crossfit exercise while wearing or not wearing a surgical face mask in a cross-over study. Two types of exercise sessions will be assessed: A high intensity interval session and a continuous exercise session. There will therefore be four exercise sessions evaluated in our randomized cross-over design: 1) high intensity exercise while wearing a face mask; 2) high intensity exercise with no face mask; 3) continuous exercise while wearing a face mask; 4) continuous exercise with no face mask. Outcome variables to be assessed include exercise performance during the sessions (total repetitions for pull-ups, push-ups, and squats during continuous exercise and total repetitions for box jumps during high-intensity exercise). Heart rate, rating of perceived exertion, and dyspnea will also be assessed throughout the exercise sessions.

Arm Intervention/treatment
Experimental: high intensity interval training wearing a face mask
high intensity interval training wearing a face mask

Experimental: continuous exercise training wearing a face mask
continuous exercise training wearing a face mask
 Other: Continuous exercise training
5 pull-ups, 10 push-ups, and 15 body-weight squats, repeated for 30 minutes
Active Comparator: continuous exercise training wearing no face mask
continuous exercise training wearing no face mask
 Other: Continuous exercise training
5 pull-ups, 10 push-ups, and 15 body-weight squats, repeated for 30 minutes


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. Change from baseline in box jumps [ Time Frame: Up to 30 minutes ]
    Number of box jump repetitions during high intensity exercise

  2. Change from baseline in pull-up, push-up, and squat repetitions [ Time Frame: Up to 30 minutes ]
    Number of repetitions performed for pull-ups, push-ups, and squats


Secondary Outcome Measures :
  1. Change from baseline in rating of perceived exertion [ Time Frame: Up to 30 minutes ]
    Rating of perceived exertion on a scale of 1-10 (Modified Borg Scale), a higher score indicates a greater perceived exertion

  2. Change from baseline in heart rate [ Time Frame: Up to 30 minutes ]
    Heart rate (beats per minute)

  3. Change from baseline in dyspnea [ Time Frame: Up to 30 minutes ]
    Dyspnea scale (0-10), a higher score indicates increased dyspnea
