Summary The purpose of this study was to test the hypothesis that 10 weeks of supervised exercise training at the maximal fat oxidation ( FAT max) intensity would improve important variables of body composition and lipid metabolism in overweight middle‐aged women. A longitudinal study design was employed to evaluate the effects of FAT max exercise training. Thirty women (45–59 years old; BMI 28·2 ± 1·8 kg m −2 ; body fat 38·9 ± 4·1%) were randomly allocated into the E xercise and C ontrol groups, n = 15 in each group. Body composition, FAT max, predicted VO 2 max, lipid profile, plasma lipoprotein lipase activity and serum leptin concentration were measured before and after the experimental period. The Exercise group was trained at the individualized FAT max intensity, 5 days per week and 1 h per day for 10 weeks. No diet control was introduced during the experimental period for all participants. Exercise group obtained significant decreases in body mass, BMI , body fat % and abdominal fat mass, as well as the concentrations of triglycerides, serum leptin and blood glucose. The activity of lipoprotein lipase was increased in trained participants. There were no changes in these variables in the C ontrol group. In addition, there was no significant change in daily energy intake for all participants before and after the experimental period. In conclusion, the 10‐week FAT max exercise training achieved improvements in body composition and lipid metabolism in overweight middle‐aged women. This result suggests FAT max is an effective exercise training intensity for obesity treatment.
