Energy intake and expenditure during sedentary screen time and motion-controlled video gaming

submitted by: LIZ_LYONS
BACKGROUND: Television watching and playing of video games (VGs) are associated with higher energy intakes. Motion-controlled video games (MC) may be a healthier alternative to sedentary screen-based activities because of higher energy expenditures, but little is known about the effects of these games on energy intakes. OBJECTIVE: Energy intake, expenditure, and surplus (intake - expenditure) were compared during sedentary (television and VG) and active (MC) screen-time use. DESIGN: Young...
