The Therapeutic Effect of Different Exercise Intensities on Weight Loss in Obese Children

High-intensity interval training (to significantly faster breathing, a significant increase in breathing depth, a significant increase in heart rate, sweating, and the need to stop exercising and adjust your breathing before you can speak; Energy expenditure (METy ≥6.00 in children) : Participants randomly assigned to HIIT will perform a 10-minute warm-up at 60-70% of their maximum heart rate (HRmax). After this, they will walk, run, or bike at 85-95% of their maximum heart rate for four sessions of four minutes each, with three minutes of active recovery (50-70% of their maximum heart rate) in between. The participants were given a five-minute cooling-off period at the end, for a total of 40 minutes of exercise. Participants will be required to participate in supervised exercise classes at least five times and up to seven times a week for 12 weeks. Each participant will be free to wear a smart electronic sports bracelet, which can be used to punch in sports.

Moderate intensity continuous training (rapid breathing, rapid heart rate, slight sweating, but still able to talk easily; Energy expenditure (children METy) 3.00 to 5.99) : Participants randomly assigned to the MICT group will walk, run, or cycle continuously for 40 minutes at 60-70% HRmax. Participants will be required to participate in supervised exercise classes at least five times and up to seven times a week for 12 weeks. Each participant will be free to wear a smart electronic sports bracelet, which can be used to punch in sports.
