The Application Of Diabetes Exercise Prescription Number 4.2 For Middle And Old Aged Patients With Type 2 Diabetes Mellitus

Objective: To investigate the exercise energy consumption in the middle and old aged patients with type 2 diabetes mellitus when they were doing physical exercise following the diabetes exercise prescription number 4.2(designed by Chen Qing-yun and published by Guangxi Golden Gulf Electronic Audio-visual Press), and the effect of this exercise prescription on patients' bodily shape, function, quality indexes and metabolism indexes. Provide the reasonable exercise reference for the middle and old aged patients with type 2 diabetes mellitus.Methods: Before and after doing physical exercise following the diabetes exercise prescription number 4.2, the heart rate in sport by Polar heart rate monitor, exercise energy consumption by Energy monitor meter, the number of walking pace showed by Pedometer and ratings of perceived exertion (RPE) in 42 patients were recorded. The patients' bodily shape, function, quality indexes and metabolism indexes were observed during the exercise. All the indexes were analyzed.Results: The heart rate curved pathway of diabetes exercise prescription number 4.2 conforms to the physiology of exercise characteristic in the middle and old aged patients with type 2 diabetes mellitus. The rang of exercise heart rate were 100～110bpm(equivalent to maximum heart rate 64%～71%) in most of time. In the exercise the energy consumption were 67.86±8.55 kcal, the number of walking pace were 1116±595.01 paces, RPE were 11.71±0.94 scores. The linear multiple regression equation about the average heart rate in exercise was Y=11.846+0.974X1+0.009X2+9.150X3﹣0.988X4,the significance examines F value =23.636, P=0.000, there were positive correlation between the average heart rate in the exercise and rest heart rate, vital capacity, sex, and the inverse correlation relations with BMI. Y was the average heart rate in the exercise, X1 was rest heart rate (bpm), X2 was vital capacity (ml), X3 was sex (male =1, female =2), X4 was BMI (kg/m2). The systolic blood pressure after stopped exercise 10 minutes decreased obviously comparing to that before (P<0.05), but diastolic blood pressure had no obvious change (P>0.05). The waist to hip ratio, FBG, 2hPBG, HbA1c, TC, BUN, UA, simple reaction time reduced obviously, and HDL-C, closed eye one-food standing test elevated after 3 months exercise comparing to that before the exercise(P<0.05), there were no significance in BMI, systolic blood pressure, diastolic blood pressure, TG, LDL-C, Cr, vital capacity, gripping power, choice reaction time and Cs-30 (P>0.05). The waist to hip ratio, BMI, FBG, 2hPBG, HbA1c, TC, TG, LDL-C, BUN, UA, simple reaction time, choice reaction time and Cs-30 reduced obviously, and HDL-C, closed eye one-food standing test, vital capacity elevated after 6 months exercise comparing to that before the exercise (P<0.05). 2hPBG, TG, choice reaction time reduced, and vital capacity, closed eye one-food standing test elevated after 6 months exercise comparing to 3 months after exercise (P<0.05).Conclusion: (1)Diabetes exercise prescription number 4.2 belongs to the medium intensity in the middle and old aged type 2 diabetes mellitus, the exercise procedure arrangement conforms to the physiology of exercise characteristic. (2)Diabetes exercise prescription number 4.2 can improve the middle and old aged type 2 diabetes mellitus's waist to hip ratio, BMI, FBG, 2hPBG, TC, TG, HDL-C, LDL-C, BUN, UA, simple reaction time, choice reaction time, closed eye one-food standing test, vital capacity and Cs-30. (3) Put patient's rest heart rate, vital capacity, sex and BMI into the formula to calculate the average heart rate, which provides certain safeguard for patients.
