“I think this study adds to the growing evidence that, along with vaccination, daily physical activity is the single most important thing you can do to prevent severe COVID-19 outcomes,” said Robert Sallis, a family and sports medicine doctor at the Kaiser Permanente Fontana Medical Center in California and former president of the American College of Sports Medicine.
