Brief summary
Exercise is an effective strategy to manage juvenile obesity; however this ideal exercise training mode is still unclear. In this study, the investigators compared the health-related effects of high intensity interval training versus endurance training in obese children.
Interventions
OTHEREndurance training
30 to 60-minute continuous exercise at 80% of the peak heart rate
OTHERHigh intensity interval training
3 to 6 sets of 60-second sprints at 100% of the peak velocity interspersed by a 3-min active recovery period.
