Moderate-intensity continuous exercise
For the MICE group, children performed a 30 min continuous endurance run on the round track at approximately 60% MAS (about 55–60% HRmax). The training progression was induced by increasing the training intensity by 10% of MAS every four weeks and further increasing it to 70% for weeks 5–8. For the HIIE group, children ran at 85% MAS during the first four weeks; then the training intensity was increased to 95% MAS for weeks 5–8.
