早晨是肝脏中含糖量最低时期,老年人若在这段时间进行体育锻炼,运动的能量将主要靠脂肪分解供给。脂肪作为能量物质进入血液后,由于机体不能有效地利用其中的游离脂肪酸,因而导致血液游离脂肪酸浓度显著增高。过剩脂肪酸所带来的毒性,往往产生各种心律失常现象,甚至引起心源性休克,使人猝然死去。对身体素质较差的老年人来说,晨练实在是得不偿失。 Morning is the lightest period in the liver sugar content, if the elderly during this period of physical activity, exercise energy will be mainly supplied by fat decomposition. After the fat enters the blood as an energy substance, the free fatty acids in the blood are significantly increased due to the inability of the body to effectively utilize the free fatty acids therein. The toxicity caused by excess fatty acids, often have a variety of arrhythmia, or even cause cardiogenic shock, sudden death. For the poor health of the elderly, morning exercise is worth the candle.
