Online interventions to increase physical activity levels in self-reported inactive adults: the ONWARDS randomised controlled trial.

ABSTRACT:

Background

Digital interventions have the potential to increase physical activity in adults with the use of few resources, but evidence of long-term effectiveness is limited. This study aimed to evaluate the effects of three digital interventions on physical activity.
