Abstract:

Objective To evaluate the effects of high-intensity interval training on patients with type 2 diabetes in comparison of moderate-intensity continuous training.Methods Seventy patients with type 2 diabetes in a tertiary hospital from June to November 2018 were selected,and were randomly divided into the high-intensity interval training group and the moderate-intensity continuous training group with 35 cases in each group. The high-intensity interval training group used the method of alternating 1-min high-intensity training（70%~90% maximum heart rate） and 1-min low-intensity training,the time were increased step by step within the range of 10~30 min/d.The other group used moderate-intensity continuous training（50%~70% maximum heart rate）,each time continued to 20~30 min,accumulated 50 min/d. Each group performed 3 days per week and insisted on 12 weeks. After 12 weeks,the index changes of 2 groups of patients before and after intervention were compared,including fasting blood glucose,2 h postprandial blood glucose,glycosylated hemoglobin,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol,body mass index,exercise self-efficacy and compliance.Results After the intervention,the index of glucolipid metabolism was better than that before intervention in both group,and the difference was statistically significant（P<0.05）. The 2 h postprandial blood glucose,glycosylated hemoglobin,body mass index,exercise self-efficacy and compliance of the high-intensity interval training group were better than those of the moderate-intensity continuous training group,and the differences were statistically significant（P<0.05）.Conclusion High-intensity interval training and moderate-intensity continuous training can effectively change the level of blood glucose and lipid in patients with type 2 diabetes,but high-intensity interval training is better to improve the level of 2 h postprandial blood glucose,glycosylated hemoglobin,body mass index,exercise self-efficacy and compliance of patients than moderate-intensity continuous training.
