In search of lost time: When people undertake a new exercise program, where does the time come from? A randomized controlled trial.
Objectives: The objective of this study was to investigate changes in use of time when undertaking a structured exercise program.Design: This study used a randomized, multi-arm, controlled trial design.Methods: A total of 129 insufficiently active adults aged 18-60 years were recruited and randomly...

Prescribed exercise was accumulated through both group and individual sessions. Use of time was measured at baseline and end-program using the Multimedia Activity Recall for Children and Adults, a computerized 24-h recall instrument. Daily minutes of activity in activity domains and energy expenditure zones were determined.Results: Relative to changes in the control group, daily time spent in the physical activity [F (2, 108)=20.21, p<0.001] and Active Transport [F (2, 108)=3.71, p=0.03] time use domains significantly increased in the intervention groups by 21-45 min/day. Comparatively, the intervention groups spent significantly less time watching television [F (2, 108)=5.02, p=0.008; -50-52 min/day], relative to Controls. Additionally, time spent in the moderate to vigorous energy expenditure zone had significantly increased in the intervention groups by end-program [F (2, 108)=6.35, p=0.002; 48-50 min/day], relative to Controls.Conclusions: This study is the first to comprehensively map changes in time use across an exercise program. The results suggest that exercise interventions should be mindful not only of compliance but also of "isotemporal displacement" of behaviors. pubtype: Academic Journal doctype: research randomized controlled trial Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
