ENERGETIC EXPENDITURE AND SUBSTRATE PREDOMINANTLY USED BY SEDENTARY YOUNG IN THE VIRTUAL REALITY GAMING

The aim of this study was evaluate energetic expenditure based on the substrate consumed by young volunteers to perform proposed activity with video game (virtual reality gaming). Each vonlunteer was informed about the procedures of the study. They were submmitted to anamnesis, physical examination and the anthropometric data were collected. Twenty two sedentary young between 18 and 30 years old were evaluated of which two were excluded due low energetic expenditure during activity when compared to the predicted value. In this study, calibrated ergoespirometry VO2000® with face mask was used to find energetic expenditure. Polar heart rate monitor was utilized for heart rate measurements during rest (30 minutes), and Xbox 360® Kinect game was employed for activities (20 minutes). Based on energetic substrate predominantly used by each volunteer, we named Group I (higher consumption of carbohydrates) and Group II (higher utilization of lipids). Most volunteers (n=17) preferentially used carbohydrates; only three volunteers predominantly spent lipids. Group I utilized more calories than Group II. Results showed that carbohydrates were the energetic substrate more used for proposed activity with video game which is probably related to the activity time/game.
