BACKGROUND: Childhood overweight and obesity have become a major global health problems and have been shown to be negatively related with cardiorespiratory fitness (CRF) level in school children and adolescents. Exercise, specifically multi-component training, is effective on CRF improvement but the main challenge is to ensure adherence to exercise in children with overweight and obesity. Therefore, the implementation of new ways of exercising more attractive and motivational for this population is needed and playing or training with active-video games (AVG) have been proposed as a good alternative because require full-body movement and therefore increase energy expenditure. OBJECTIVE: The main aim of this study was to investigate the effects of an AVG intervention combined with multicomponent training on CRF at both maximal and submaximal intensities in children with overweight or obesity. METHODS: 28 children (13 girls) aged 9 to 11 years with overweight or obesity recruited from medical centers were divided into two groups, an intervention group (n = 20) that participated in a 5-month AVG supervised exercise program combined with multicomponent exercise, and a control group (n = 8) that continued their daily activities without modification. A maximal stress test to measure CRF using a walking-graded protocol with respiratory gas-exchange was performed by the participants. RESULTS: AVG group showed a significant decrease of the AVG group on heart rate and oxygen uptake for the same intensities on the submaximal stages of the maximal treadmill test, showing also lower oxygen uptake percentage according to their individual maximal oxygen uptake, while the control group did not show overall changes. No change in peak oxygen uptake was found. CONCLUSIONS: A 5-month intervention of AVG combined with multicomponent exercise had positive effects on CRF at submaximal intensity, showing lower heart rate and oxygen uptake at the same intensities and displaying a lower oxygen uptake percentage according to their individual peak oxygen uptake. Greater benefits were found in children with the highest fat percentage. CLINICALTRIAL: CinicalTrials.gov NCT04418713.
