BACKGROUND: Compared with the moderate-intensity continuous movement, high-intensity interval training is more time-sensitive and effective for reducing abdominal fat. OBJECTIVE: To investigate the effects of different forms of high-intensity interval training at the same intensity and time on energy expenditure and substrate metabolism in obese young women from the perspective of energy metabolism. METHODS: The gas metabolism of seven obese young women in two different intermittent forms of high-intensity intermittent exercise was analyzed by gas metabolism analyzer. The subjects underwent thrice test: maximal oxygen uptake, 90%VO2peak at low-frequency high-intensity interval training (low-frequency group), and 90%VO2peak at high-frequency high-intensity interval training (high-frequency group). Exercise was performed once every 1 week and early follicle was avoided. The study was approved by the Ethics Committee of Sports Institute of Hebei Normal University. The subjects participated in the study voluntarily, and signed the informed consent. RESULTS AND CONCLUSION: (1) The blood lactate concentration, glycolysis energy supply and anaerobic glycolysis energy supply after exercise in the high-frequency group were significantly lower than those in the low-frequency group (all P < 0.01). (2) The fat energy supply, sugar energy supply and total energy expenditure during exercise in the high-frequency group were significantly lower than those in the low-frequency group (P < 0.05 or P < 0.01). The sugar energy supply at interval time in the high-frequency group was significantly higher than that in the low-frequency group (P < 0.05), and the fat energy supply and total energy expenditure in the high-frequency group were significantly higher than those in the low-frequency group (P < 0.01). (3) The fat energy supply at convalescent period in the high-frequency group was significantly lower than that in the low-frequency group (P < 0.05), and the total fat energy supply in the high-frequency group was significantly higher than that in the low-frequency group (P < 0.05). (4) These results indicate that intermittent frequency changes during high-intensity interval training can reduce the accumulation of blood lactic acid, promote the mobilization and oxidation of fat, and change the ratio of glycolipid energy supply under the same energy consumption.
