The Effect of an Intervention with Active Video Games Combined with Multicomponent Exercise on Cardiorespiratory fitness in Children with Overweight and Obesity: A Randomized Controlled Trial.
ABSTRACT
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. In addition, the study aims to examine the relationships between body composition and CRF variables in children with overweight and obesity.
Methods:
28 children (13 girls) aged 9 to 11 years with overweight or obesity were divided into two groups, an intervention group (n=20) that participated in a 5-month AVG 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 HR and VO2 for the same intensities on the submaximal stages of the maximal treadmill test, showing also lower VO2 percentage according to their individual maximal oxygen uptake, while the control group did not show overall changes. No change in VO2peak was found.
Conclusions:
A 5-month intervention of AVG combined with multicomponent exercise had positive effects on CRF at submaximal intensity, showing lower HR and VO2 at the same intensities and displaying a lower VO2 percentage according to their individual VO2peak. Greater benefits were found in children with the highest fat percentage. Clinical Trial: Identification number in clinicaltrials.gov: NCT04418713
