Effect Of Nordic Walking Exercise Intervention On Impaired Glucose Regulation

ObjectiveThe improvement of people’s living standard has brought great change to the life style. Ahigh-fat diet and sedentary lifestyle has led to high incidence of diabetes and impaired glucoseregulation and trend in young person. Diabetes can’t be cured, but impaired glucose regulation isreversible. It is the transitory stage of develop diabetes. We aimed to study the pathogenesis ofimpaired glucose regulation, and the effect of Nordic Walking exercise intervention on old people,to provide a new exercise therapy for the impaired glucose regulation, to reduce the incidence ofdiabetes and improve patients’ life who has impaired glucose regulation.MethodEighteen patients with impaired glucose regulation were given the medical and physicalexamination. All the baseline levels blood index, fatty liver index, body shape index and physicalquality index, are similar. All the subjects were randomly assigned into two groups: exercise groupand control group. Exercise group did moderate intensity Nordic Walking for6months, threetimes a week, and every time30-60minutes.Subjects’ daily exercise habit and daily effective stepsmeasured with movement log and pedometer. After six months, we examined all subjects’ indexagain. We compared the difference between exercise group before intervention and after, weobserved a significant difference between exercise group and control group by the statisticalmethod of paired t-test and independent t-test. However, there was no significant differencebetween control group before intervention and after.ResultComparison with control group and six months ago (before taking the intervention), fastingblood glucose level, high density lipoprotein level, low density lipoprotein, cholesterol andtriglyceride level were all decreased (p<0.05) in exercise group, especially body fat rate (p<0.05).And fatty liver level of exercise group was improved. Weight presented a downward trend bonemineral density has a slight tendency to increase. Taking intervention group was higher thancontrol group and before taking intervention group in2kms walking speed, step-test index, gripstrength, elbow flexion strength and extension of the knee strength, but lower in quiet heart rate.ConcludeNordic walking exercise intervention can decrease the body weight, body fat rate of impairedglucose regulation people and increase the basal metabolic rate. So it will reduce obesity anddiabetes risk factors, improve cardiopulmonary function. Also, it is helpful to enhance the musclestrength and the physical quality of impaired glucose regulation people and delay or preventdiabetes.
