Effect Of High Intensity Interval Training On Cardiovascular Disease Risk Factors In Type 2 Diabetes Mellitus

Objective:The prevalence and death rates of chronic diseases are increasing as people's physical activity decreases,population aging,sedentary behavior and other lifestyle changes.Among them,the morbidity and mortality of diabetes have been a common concern of the world for many years,and among the complications of diabetes,the mortality caused by cardiovascular disease is the most serious.Numerous studies abroad have proved that diabetes and cardiovascular disease often have the same risk factors.In recent years,high-intensity interval training as a means of exercise has attracted the attention of many scholars.In the context of the integration of physical medicine,this study combined medical means with physical exercise to explore the effects of high-intensity interval training on cardiovascular risk factors such as body composition,cardiopulmonary fitness and glucose and lipid metabolism of type 2 diabetes,and to provide valuable references for finding suitable exercise methods for patients with type 2 diabetes.Methods:The research subjects of this study were all 20 patients with type 2 diabetes in Shanghai Yangpu District Central Hospital,aged 27-64 years old,13 males and 7 females.Take a combination of diagnosis by doctors,sports training experts,nutritionists,combined with the diagnosis results and the opinions of the three parties to decide whether to carry out sports intervention,before the intervention,first investigate the patient's exercise habits,eating habits,working hours,etc.,then,the patient Perform medical examinations,including fasting blood sugar,glycated hemoglobin,triglycerides,total cholesterol and other blood glucose and lipid indicators,and then exercise instructors to test the patient's height,weight,BMI,body fat rate,and maximum oxygen uptake According to the measured maximum oxygen uptake level,two training methods,high-intensity interval training and mediumintensity continuous training,were developed for the patients.Highintensity interval training uses a power bike for 1 minute exercise(85%-90% VO2max),1 minute passive rest or active rest(25%-30% VO2max)exercise,a total of 10 groups.Medium-intensity continuous training uses a power bike for 40 minutes of continuous training(50%-60% VO2max).During the intervention,exercise instructors and hospital doctors are responsible for supervising the completion.After the intervention,the patients' fasting blood glucose,glycated hemoglobin,total cholesterol,triglycerides,body weight,BMI,body fat rate and other indicators are tested.Analyze and statistically analyze the results of the two groups of interventions to observe the impact of high-intensity interval training and moderate-intensity continuous training on cardiovascular risk factors in patients with type 2 diabetes.Results:1.The weight,BMI and body fat rate of the two groups of patients before and after the intervention have decreased and have significant differences(P <0.05),but there is no significant difference between the two groups.2.The cardiopulmonary fitness of the two groups of patients before and after the intervention is improved and has a significant difference(P <0.05),and there is a significant difference between the two groups(P = 0.021)3 The fasting blood glucose,glycated hemoglobin,120 min blood glucose,and HOMA-IR of the two groups of patients before and after the intervention were improved and had a significant difference(P <0.05),but only HOMA-IR was significantly different between the two groups(P = 0.047),other indicators have no significant difference4 Before and after the intervention,the high-density lipoprotein and low-density lipoprotein of both groups were improved and had statistical significance(P <0.05),and there was no statistically significant improvement in total cholesterol and triglyceride,and the two groups were There is no difference in the improvement of metabolism.Conclusion:1.Both high-intensity interval training and moderate-intensity continuous training can reduce body weight,BMI,and body fat rate.2.Both high-intensity interval training and medium-intensity continuous training can increase the patient's maximum oxygen uptake level and improve cardiorespiratory fitness.But the effect of highintensity interval training is better than that of medium-intensity continuous training.3.Both high-intensity interval training and moderate-intensity continuous training can reduce the patient's fasting blood glucose,glycated hemoglobin,blood glucose 2 hours after a meal,reduce HOMAIR,improve blood glucose and increase insulin sensitivity.However,the improvement effect of high-intensity interval training on HOMA-IR is better than that of medium-intensity continuous training,and it is better in improving insulin sensitivity.4.Both high-intensity interval training and medium-intensity continuous training can improve the patient's high-density lipoprotein and reduce low-density lipoprotein.
