The purpose of this study was to investigate the effects of 8 weeks of supervised exercise training at the exercise intensity at which the maximal fat oxidation occurred (Fat_max intensity) on body composition and cardiorespiratory function in overweight young women. Fifty sedentary female university students [aged 20-23 years, body mass index (BMI) >25?kg/m²] were enrolled in the study. The maximal fat oxidation rate was measured using a graded treadmill running test; the average result of the participants was 0.43?¡À?0.01?g/minute, which occurred at the exercise intensity of 54.0?¡À?4.0 % maximal oxygen consumption (VO_2max), and the corresponding heart rate was 134?¡À?3 beats per minute. The individualized heart rate at the Fat_max intensity was applied in the exercise training program. The trained individuals decreased their body mass, BMI, fat mass, waist-hip ratio, fasting plasma triglycerides, and total cholesterol concentrations and increased their VO_2max and heart rate index in a step test. There were no changes in these variables in the control group. In conclusion, exercise training at the Fat_max intensity is an evidence-informed and safe exercise prescription for overweight young women.
