Methods Youthmotivation to be physically active as a function of the socialcontext was measured using a computerized relative reinforcingvalue task to earn points exchangeable for physical and/or sedentaryactivities. Results The presence of a friend (p<.001)increased youth's; motivation to be physically active. The presenceof a peer increased overweight youth's; motivation to be physicallyactive, whereas this was not the case for lean youth (p=.47).Participants biked a greater distance in the presence of a friendthan when alone (p<.001). Overweight youth biked a greaterdistance in the presence of a peer than when alone, while thiswas not the case for lean youth (p=.23). Conclusions Friendshipsmay increase youth's; motivation to engage in physical activityand promote greater physical activity in non-overweight andoverweight youth. |
