Immersive Physical Activity Program for Overweight Schoolchildren

Childhood overweight and obesity are major public health concerns associated with increased cardiometabolic risk and reduced quality of life. In Galicia (Spain), approximately one-third of schoolchildren aged 7-15 years are affected. Physical inactivity and sedentary behaviors contribute significantly to this condition. The PEESO Project is a clinical trial designed to evaluate the effects of an immersive virtual reality-based physical exercise program delivered during school recess in children with overweight or obesity. The intervention uses head-mounted displays to promote moderate-to-vigorous intensity physical activity in an engaging environment.
