Abstract: In order to compared the body’s BMI and blood lipid metabolism changes after short-term aerobic exercise and high-intensity intermittent training, and to probe into short-term high-intensity intermittent training’s role in pro-moting blood lipid metabolism, the authors divided 16 male students at Guangzhou Sports University into 2 groups af-ter having tested their maximum oxygen uptake, let them respectively do an aerobic exercise (exercise intensity: 60%VO2max, 2×30 min, interval 5 min) or have high-intensity intermittent training (exercise intensity: 80%VO2max, slope 8%, 4×12 min, interval 5 min) once a day for 8 d, and before the experiment and in the next morning after the last exercises in the two ways were done, measured the testees’ height and weight and calculated their BMI, collected elbow venous blood in a fasting condition, tested blood lipid related indexes, and calculated the radios of TC/HDL-C and LDL-C/HDL-C. The authors revealed the following findings: as compared with that before the experiment, the testees’ BMI after aerobic exercise and high-intensity intermittent training showed no significant difference (P>0.05), also showed no difference between the two different exercise ways (P>0.05); after aerobic exercise, only TG and LDL-C/HDL-C showed a significant decrease (P<0.05); after high-intensity intermittent exercise, such indexes as TC, TG, NEFA, LDL-C, TC/LDL-C and LDL-C/HDL-C showed a significant or very significant decrease (P<0.05, P<0.01), HDL-C showed a significant increase (P<0.05); as compared with those after aerobic training, after high-intensity intermittent exercise, TC showed a very significant decrease (P<0.01), TC/HDL-C and LDL-C/HDL-C showed a significant decrease (P<0.05). The said findings indicate that high-intensity intermittent training can improve the blood lipid environment inside the body better than short-term aerobic exercise.
