Reduction in cardiopulmonary and cognitive performance after COVID-19 in a competitive athlete.

A 23-year-old male competitive athlete performed a maximal cardiopulmonary exercise test on a cycle ergometer with a concurrent cognitive test on an iPad 6 days before and 19 weeks after a nonhospitalized COVID-19 illness. Results indicated reductions in time to exhaustion (-3.25 min), peak oxygen consumption (-1.68 mL/kg/min), and accuracy (-8%) during peak exertion despite his return to prior levels of activity. Reductions in functional or cognitive performance in competitive athletes may elicit noticeable differences in athletic performance; therefore, fitness specialists should consider the assessment of both cognitive function as well as aerobic capacity in athletes following COVID-19, regardless of severity, to facilitate safe and effective return to activity.
