Physical Activity
Conditions
Brief summary
This is a 3-arm trial to compare exercise videogames versus traditional standard exercise using stationary bikes and treadmills versus a control condition. Results will examine minutes of physical activity at 12 weeks and 6 month follow up between conditions. We will also examine changes in indicators of cardiovascular health (e.g., body mass index, lipids) and changes in psychological factors that may be predictive of continued exercise engagement.
Detailed description
To test the efficacy of a 12-week supervised, laboratory based program of an exercise videogame (EVG) program to increase time spent in moderate-to-vigorous physical activity (MVPA) and improve cardiovascular health and fitness indices compared to Standard and Control programs. Participants will be randomly assigned to (1) a supervised program of Exercise Videogames (EVG); (2) a supervised standard exercise program (Standard), using aerobic exercise equipment (e.g., treadmill, stationary bike); or (3) a Control condition. We will also examine the effect of home-based exercise videogames compared to a home-based standard PA program on MVPA maintenance during the 6-month follow up period. We will examine changes in cardiorespiratory fitness (i.e., estimated VO2max), blood pressure, resting heart rate, body composition and blood lipids at baseline, week 12 and at 6-months follow up. We will also examine changes in theoretically-based cognitive and affective constructs associated with physical activity including: enjoyment, outcome expectations, self-efficacy, motivation, and goal-orientation.
