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. |
