Increased objectively measured physical activity is associated with improved levels of energy and fatigue in a web-based physical activity RCT

Physical activity is known to improve health related quality of life (HRQoL) yet few studies assess the impact of changes in objectively measured physical activity in a web-based physical activity intervention in relation to changes in HRQoL. Data from the baseline and 3 month follow-up assessments of the WALK 2.0 trial were used for analysis (n = 504). WALK 2.0 is a 3 arm randomised controlled trial investigating the effects of Web 2.0 applications on engagement, retention, and subsequent physical activity behaviour change. Study outcomes indicate that web-based physical activity interventions can improve physical activity and that these increases are associated with improved ratings of energy and fatigue.
