Adherence
Maintaining or initiating regular physical activity is associated with improved cardiorespiratory fitness (measured by maximal treadmill test time) in healthy adults aged 25-55, with the greatest improvements seen in those with lower baseline fitness who transition from sedentary to active.
If you are currently sedentary, starting any regular physical activity (like walking or jogging) will significantly improve your cardiorespiratory fitness, potentially more so than if you were already active. You do not need to be an athlete to see benefits; simply moving more is the key lever for improving treadmill endurance.
GoodSupportsHIGH confidence
In the follow up study, persons who remained or became active had better MTT than persons who remained or became sedentary. ... Participants in the lowest quintile had more improvement in cardiorespiratory fitness if they changed from a sedentary to an active lifestyle than did participants in the higher baseline fitness groups.
Why this rating
Large longitudinal cohort (n=5707) with controlled covariates, but relies on self-reported physical activity.
