We studied the effects of prior high-intensity cycle exercise (85% VO2 max) on total energy expenditure (EE) and the thermic effect of insulin (TEI) in normal controls and in obese insulin-resistant and noninsulin-dependent diabetic (NIDDM) subjects. Normal controls, but not obese or NIDDM subjects, showed a significant increase (3-7%) in total EE 12-16 h after exercise (p less than 0.05). Prior exercise increased lipid and decreased glucose oxidation in all groups. During low-dose insulin infusion (40 mU X M2 X min), prior exercise potentiated TEI in control and NIDDM subjects (p less than 0.05), whereas obese subjects showed no response. During high-dose insulin infusion (400 mU X M2 X min), TEI was similar in NIDDM and control subjects but was significantly less in the obese group. In this study, we found a positive correlation between TEI and insulin-stimulated rates of glucose disposal (r = 0.91, p less than 0.001). The predicted cost of glucose storage accounted for 42% of TEI.
我们研究了先前的高强度自行车运动(85%最大摄氧量)对正常对照组、肥胖胰岛素抵抗和非胰岛素依赖型糖尿病(NIDDM)受试者的总能量消耗(EE)和胰岛素热效应(TEI)的影响。正常对照组在运动后12 - 16小时总EE显著增加(3 - 7%)(p < 0.05),而肥胖或NIDDM受试者未出现此现象。先前的运动使所有组的脂质氧化增加,葡萄糖氧化减少。在低剂量胰岛素输注期间(40 mU×M2×min),先前的运动增强了对照组和NIDDM受试者的TEI(p < 0.05),而肥胖受试者无反应。在高剂量胰岛素输注期间(400 mU×M2×min),NIDDM和对照组受试者的TEI相似,但肥胖组显著较低。在本研究中,我们发现TEI与胰岛素刺激的葡萄糖处置率之间呈正相关(r = 0.91,p < 0.001)。葡萄糖储存的预测成本占TEI的42%。
