摘要：The present study aimed to examine whether a single bout of percutaneous low-frequency electrical muscle stimulation (EMS) can attenuate postprandial hyperglycemia in human subjects. Ten obese and 4 pre-obese Japanese men participated in two experimental sessions, one involved 20 min of EMS just after a breakfast (EMS trial) and the other involved complete rest after a breakfast (Control trial). In each trial, blood samples were taken before and at 30, 60, 90, and 120 minutes after the meal. Blood lactate concentration and respiratory gas exchange were measured during EMS and at complete rest after a meal in the EMS and Control trials, respectively. The results showed that the postprandial hyperglycemia was significantly attenuated in the EMS trial (P<0.05). Also, the postprandial increase of blood insulin was significantly attenuated in the EMS trial (P<0.05). However, blood triglyceride was not affected by EMS. In addition, blood lactate significantly increased (P<0.05), and the respiratory quotient tended to elevate during EMS. These results demonstrate that EMS can be an effective method to attenuate postprandial hyperglycemia by enhancing glucose metabolism in contracted muscles.
