Masks are recognized as important tools in the fight against the COVID-19 pandemic. To save medical-grade masks for hospital personnel, people have adopted reusable cloth masks for everyday use. Researchers have studied the efficacy of mask use, but what about the effects of wearing a cloth face mask on sports performance? A new study by Baylor Scott & White Research Institute (BSWRI) has now shed light on the matter. The research team at Baylor Scott & White Sports Therapy & Research at The Star in Frisco, conducted a study on the effects of cloth mask use during exercise. Their work, which shows that cloth masks reduce exercise performance at a range of intensities, was published in the British Journal of Sports Medicine last month.
