OBESITY, CRF, CHRONIC DISEASE
Obesity is a serious chronic disease that has become a global public health burden [Although MICE has been proven as the most common exercise to improve body composition [Significantly, the entertainment and enjoyment of children during and after HIIE are very important for long-term exercise adherence [Therefore, this study aimed to investigate the effect of two 8-week of school-based exercise training modalities (HIIE and MICE) on (a) body composition, (b) muscular fitness, and (c) cardiorespiratory fitness (CRF) assessments in children with overweight. We hypothesized that HIIE would produce more effects than MICE for improving body composition, and there would be a corresponding increase in muscular fitness and CRF because half of total training time is spent working at greater than 80% HRmax during HIIE, which could produce a considerable beneficial adaptation.
