Researchers from the University of California, San and Zuckerberg Hospital in San Francisco analyzed the results of nine studies on long Covid effects on the physical performance. The physical performance of 359 people infected with Covid and cured was compared to that of 464 people suffering from a long Covid. The patients were between 39 and 56 years oldtheir body mass index was between 23 and 30 (i.e. between overweight and obesity).
