Mask wearing during the Covid-19 pandemic has been proven substantially effective in containing the spread of infection, with cloth masks being the most universally used. However, cloth masks may be uncomfortable and have physiological repercussion during exercise. This study aims to investigate the impact of cloth masks during exercise.
