中老年人能量代谢特点研究综述

Review of Studies on Energy Metabolism Characteristics in Middle-Aged and Elderly People

目的了解中老年人能量代谢特点及其变化机制,以及运动对中老年人能量代谢的影响。方法文献资料法。结果与结论随着中老年人年龄的增长,中老年人的能量代谢特点出现变化,主要特点是,有关体力活动的能量消耗降低,基础代谢下降,原因是骨骼肌、神经系统、心血管系统、呼吸系统等的功能下降,老年人活动受限以及产能器官线粒体的功能退变所导致。有氧运动与抗阻力运动对中老年人的能量代谢和基础代谢具有一定的促进作用。

Objective To investigate the energy metabolism characteristics and its mechanism in middle-aged and elderly people, and the effect of exercise on energy metabolism in middle-aged and elderly people. Methods Literature Review. Results and Conclusion The characteristics of energy metabolism of middle-aged and elderly people change as they grow older. The main characteristics are that energy consumption related to physical activity decreases and basic metabolism decreases, which are caused by functional degeneration of skeletal muscle system, nervous system, cardiovascular system, respiratory system, activity restriction and mitochondrion.Aerobic exercise and resistance exercise can promote the energy metabolism and basal metabolism of middle-aged and elderly people.
