USask researchers find face masks don’t hinder breathing during exercise

Posted on

A new University of Saskatchewan (USask) study has found that exercise performance and blood and muscle oxygen levels are not affected for healthy individuals wearing a face mask during strenuous workouts.

Questions have been raised as to whether mask wearing during vigorous exercise might compromise oxygen uptake or increase the rebreathing of carbon dioxide, leading to a condition (hypercapnic hypoxia) whereby increased carbon dioxide displaces oxygen in the blood.
