运动需要较大的代谢和心血管调节以增加对肌肉供应的能源和氧,同时还要维持对脑和其他生命器官的供应。此时骨骼肌明显地提高了其利用贮存的糖原和甘油三酯,以及从脂肪组织甘油三酯分解而来的游离脂肪酸和由肝脏释出的葡萄糖的能力。在正常人中这种多器官的相互作用表现出调节极为严密。即使在剧烈运动时,血糖水平变动也很少。除在长时间剧烈运动例如马拉松跑时偶可发生外,明显的低血糖不会出现,中枢神经系统功能也得以保持。这种对运动的细致
Exercise requires greater metabolism and cardiovascular regulation to increase energy and oxygen supply to the muscles, while maintaining the supply of the brain and other vital organs. At this time skeletal muscle significantly enhances its ability to utilize stored glycogen and triglycerides, as well as free fatty acids that are broken down from adipose tissue triglycerides and glucose released by the liver. In normal people this multi-organ interactions show very tight regulation. Even in strenuous exercise, blood glucose levels change very little. In addition to occasional occurrence of prolonged strenuous exercise such as marathon run, obvious hypoglycemia does not occur, and central nervous system function is maintained. This kind of movement of detail
