| Outline of Final Research Achievements |
This study investigated how an 8-week, 3 times/week exercise intervention (EXi) incorporating either high-intensity, interval training (HIIT, 13 min, 180 kcal) or moderate-intensity continuous training (MICT, 40 min, 360 kcal) followed by a 4-week low-calorie diet intervention (LCDi, 4 counseling sessions) affects metabolic syndrome risk factors. During the EXi, cardiorespiratory capacity improved more through HIIT (25.4 ± 14.6%) than through MICT (14.9 ± 12.8%), whereas improvements in body fat and HDL cholesterol were similar. During the LCDi, some risk factors improved further without any group differences. An intervention strategy consisting of 8 weeks of either HIIT or MICT followed by a 4-week LCDi has a positive effect on metabolic syndrome risk factors.
