Effect of single exercise intervention on the plasma glucose and insulin of female undergraduates with impaired glucose tolerance

OBJECTIVE To explore the effects of single postprandial exercise intervention on plasma glucose and insulin of young female students with impaired glucose tolerance(IGT),and to provide the theoretical basis and reference for exercise nursing intervention to young female college students with IGT,and for college health care. METHODS 14 subjects came from 29 IGT,who were screened from 1163 female undergraduates,were beginning to participate in different time and different intensity exercise intervention trial. At each time point on rest and exercise days,blood samplings were drawn for detecting the levels of plasma glucose and insulin,calculating each group’s Glucose Area Under the serum concentration Curve(GAUC)and Insulin Area Under the serum concentration Curve(IAUC),monitoring exercise intensity and exercise energy expenditure. RESULTS The peak of plasma glucose was controlled within postprandial 15-45min,at postprandial 15min and 30min point before the Peak of plasma glucose,which decreased by 17.90% and 37.82%,respectively. While the postprandial 60min and 90min point exercise,plasma glucose peak was still at 60min point,resting on flat level of rest day. Before 60min time point,30min’s exercise affected the peak of insulin(P﹤0.05),which appeared ahead of time at least 30min,and there were features of the earlier movement the sooner peak of insulin. No matter what point of time and time quantum 30min,exercise can reduce the GAUC and IAUC of female students with IGT within postprandial 180min. CONCLUSION The optimum effect of single postprandial exercise intervention on plasma glucose and insulin of young female undergraduates with IGT was 30min’s medium intensity exercise intervention at postprandial 30min time point.
