Moderating effect of social interaction on enjoyment and perception of physical activity in young adults with autism spectrum disorders.

Background: Young adults with autism spectrum disorder (ASD) are at increased risk for a sedentary lifestyle and its associated health problems. In neurotypical (NT) individuals, social participation and enjoyment are related to physical activity engagement. Exergaming has been shown to increase energy expenditure compared to traditional video games and is an effective option for community-based recreation. Methods: We measured physiological and psychological responses of young adults with ASD to exergaming under varying conditions and sought to determine whether playing alone versus with a partner influenced physical activity level and/or experience in NT young adults (n = 18) and those with ASD (n = 18). Results: Both ASD and NT groups experienced high enjoyment and perceived exertion while exergaming. Perceived exertion was moderated by enjoyment when young adults with ASD played with a partner, reporting less effort despite actually expending more energy. Conclusion: Social interaction may lead to increased intensity and duration of physical activity for individuals with ASD. Exergaming is a socially acceptable and age-appropriate exercise modality for this group and likely represents a cost-effective and accessible way to incorporate physical activity and social interaction into their daily lives.
