Brief summary

This study investigated the effects of two exercise modalities: high-intensity interval training (HIIT) and maximal fat oxidation (FATmax) exercise on fat loss in overweight young women. Participants were randomly assigned to either the HIIT or FATmax group, underwent an 8-week supervised exercise intervention.

Detailed description

This study aims to compare the effects of HIIT and FATmax exercise on fat loss in overweight young women. Participants were recruited and randomly assigned to either the HIIT group or the FATmax group. The intervention lasted for 8 weeks, during which participants maintained their usual diet. Both body morphology and body composition were assessed before and after the intervention. In order to recommend exercise strategy for overweight young women reduce fat and improve their health.
