简要总结
Sedentary behaviors have been shown to increase food consumption among youth and adults. The recent active video games devices have been suggested to compensate for the increased energy intake they induce by the increased energy expenditure they generate. To date no study has been conducted to question whether or not such modern sedentary activities induce energy consumption modification in youth. The aim of this work is to compare the impact of a passive video games vs. active video games vs. physical exercise in terms of subsequent energy intake and appetite feelings in normal weight and obese youth.
详细描述
After a medical inclusion, the adolescents will have to realise a DXA to assess their body composition and a submaximal exercise to evaluate their aerobic capacities.
They will have then to enter the laboratory on three different occasions in a randomized order from 8am to 730pm: At 8am they will receive a calibrated breakfast. then, at 1045; they will have to complete one of the experimental condition: 1) one hour of passive video game; 2) one hour of active video game; 3) a cycling exercise. at 1215 and 0630pm, they will be offered ad libitum meals. At regular intervals through the day, their appetite feelings will be assessed using Visual analogue scales.
Energy expenditure will be assessed thanks to cardiofrequencemeters during the 1h PVG and and by indirect calomitery (K4b2) during the active video game.
Ad libitum energy consumption will be assessed by investigators and recorded for each participants.
