The current COVID-19 lockdowns cause both a decrease in physical activity (PA) and sedentary behavior (SB). This applies to both healthy individuals and several patient populations, including some which have been shown to benefit from PA, such as type 2 diabetes.
The largest changes in PA are seen in people with greater pre-lockdown PA levels. There is also a large decrease in the training volume and intensity of elite athletes. Considering the positive results of digitally-delivered PA during the first lockdown, this strategy should be applied widely in future similar situations.
