Functional limitations and exercise intolerance in patients with post-COVID condition

JAMA Network Open

Peer-Reviewed Publication

JAMA Network

About The Study: In this randomized crossover clinical trial with 62 participants, non-hospitalized patients with post-COVID condition (PCC) generally tolerated exercise with preserved cardiovascular function but showed lower aerobic capacity and less muscle strength than the control group. They also showed signs of postural orthostatic tachycardia and myopathy. The findings suggest cautious exercise adoption could be recommended to prevent further skeletal muscle deconditioning and health impairment in patients with PCC. 

Authors: Andrea Tryfonos, Ph.D., of the Karolinska Institutet in Stockholm, is the corresponding author.
