Abstract:

The aim of this study was to investigate the effect and biological mechanism of FATmax intensity exercise on peripheral arteriosclerosis in obese college students. 30 obese college students were selected as the exercise group and 30 obese college students as the control group. The exercise group received 12-week FATmax intensity exercise, while the control group did not engage in any systematic physical activity. Before and after the test, the two groups of subjects were tested for body composition, synchronized limb blood pressure, brachial-ankle pulse velocity measurement, and NO, NOS, ET-1. The results showed that after the test, body weight (P=0.022, ES=0.701), body fat percentage (P=0.032, ES=0.672), BMI (P=0.038, ES=0.662) showed an interaction between group and time. The exercise group was significantly lower than that in the control group (P<0.05). Left BAI (P=0.030, ES=1.207), left BAI (P=0.010, ES=1.000), left baPWV (P=0.037, ES=0.760), right baPWV (P=0.024, ES=0.841) showed an interaction between group and time. After the experiment, the left BAI and right BAI of the exercise group were significantly higher than those in the control group (P<0.05), and the left baPWV and right baPWV were significantly lower than those in the control group (P<0.05); NO (P=0.032, ES=0.503), TNOS (P=0.043, ES=0.470) showed an interaction between group and time. Among them, NO and TNOS in the exercise group after the test were significantly higher than those in the control group (P<0.05). The result of research shows that 12-week FATmax intensity exercise can significantly reduce the body weight and body fat rate of obese college students, and improve the arteriosclerosis index. The increase of NO may be one of the important biological mechanisms, but the path of NO needs further research.
