Clinical Trial Summary
The coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) is highly transmittable person-to-person when an infected
individual coughs, sneezes or talks while within at least 6 feet (1.8 m) of a neighboring
individual. Guidelines set forth by the Centers for Disease Control and Prevention (CDC)
state that nose and mouth facial coverings are recommended at all levels for source control
as a simple barrier to help prevent respiratory droplet transmission. It is important to
remember that increased viral shedding occurs during elevated ventilatory rates that are
observed during exercise within a shared space, such as gyms or fitness studios increase the
rate of transmission. However, there is limited research studying the effects of mask use
during exercise, and no research evaluating these effects specifically during
resistance-based exercise. Therefore, the purpose of this investigation is to examine the
effects of wearing a surgical face mask while performing resistance exercise on average peak
force, total work, heart rate (HR), oxygen saturation (SpO2) and breathing discomfort.
Description:
Despite the accumulating evidence supporting the favorable impact and potentially life-saving
benefits of routine public mask wearing has on lowering the risk of COVID-19 transmission,
recommendations for mask use have been met with resistance by some individuals. With the
numerous health benefits greatly outweighing the document complaints of discomfort and
headaches, it becomes puzzling why there is not universal support for these recommendations
made by experts. Additional insight to this ongoing issue is provided in an extremely
informative commentary provided by Scheid et al, in which they present theoretical evidence
suggesting that there may be consequential psychological impacts of mask wearing on the basic
psychological needs of competence, autonomy, and relatedness. Which may contribute to the
controversy associated with mask use. It is also important to consider that such subjective
experiences caused by mask wearing have been demonstrated to be exacerbated when physical
exertion is performed at intensities above activities of daily living, such as during
incremental aerobic or resistance exercise.
Currently, the CDC identifies age > 65, BMI > 30, diabetes, smoking, chronic obstructive
pulmonary disease, heart conditions, or an immunocompromised state as risk factors for severe
illness from COVID-19. Research conducted by Barkley et al, revealed that university closure
increased sedentary behavior in all study participants, but only decreased physical activity
in individuals who were the most active pre-cancellation. Highlighting concerns that
pandemic-related closure of facilities such as gyms, which are designed for physical activity
may disproportionately impact a more active population. Increased sedentary behavior and
reduced physical activity will likely exacerbate these known risk factors for severe illness
from COVID-19, and contribute to overloading our healthcare systems . While it is still
recommended that adults of all ages should achieve 150-300 minutes of moderate or 75-150
minutes of vigorous (or an equivalent combination) physical activity per week, along with at
least 2 days per week of muscle strengthening activities. Unfortunately, evidence based
guidelines have not yet been developed to guide universal mask use during exercise and
sporting events.
In this proposed randomized controlled cross-over study, we aim to evaluate in non-COVID-19
infected and otherwise healthy young-to-middle aged adults whether compared with performing
resistance exercise (RE) with no mask (NM), 1) are there effects of wearing a surgical mask
on physiological or psychological responses during RE that limit peak force or work performed
in an exercise session, and 2) does wearing a surgical mask during resistance exercise yield
clinically relevant and dangerous absolute indications warranting early exercise termination.
Isokinetic testing can be used to provide valid, reliable, objective measure of a muscle's
performance and offers significant clinical controls to simulate a resistance training
workout. The lever arm speed measuring muscular output by the participant can be adjusted
depending on the desired number of repetitions or duration test performed. Various skeletal
muscle metabolic systems could be stressed depending on the effort and duration of time under
tension, making it an efficient and reliable method for the assessment of muscle performance
under various environmental conditions, including wearing a mask during a resistance training
workout. To our knowledge this is the first study to assess the effects of wearing protective
nose and face covering on resistance exercise capacity, estimate arterial oxyhemoglobin
saturation (SpO2), and degree of discomfort.
