Masking the real problem: Does wearing a face mask during running make it feel harder or are you just unfit?

Dr Breanne Kunstler (BBiomedSci, BHealthSci, MPhysio, PhD). Physiotherapist, behaviour change scientist and run coach. Aim: Establish the effects of wearing a facial mask on perceived exertion and physiological outcomes during running. Method: One 31-year-old woman (max HR = 189 beats per min) pushing a pram with one 10 month-old-child (weight = heavy) ran* 2.7km twice while attending a work meeting. The second run was completed while wearing a three-layered facial mask. The space between each run involved getting the grocery shopping done, allowing heart rate and perceived exertion to reach normal levels. One Garmin Forerunner™ watch measured physiological outcomes (heart rate [HR] and percentage heart rate maximum [%HRMax]). Distance, time to complete and pace was also recorded using the watch. Rating of perceived exertion was measured on a scale of 0 (as easy as sleeping) to 10 (exhausting). Results: The two runs were successfully completed with baby and pram in situ, as we...
