运动可引起人体在生理及生化方面发生显著改变,也有助于心血管疾病的防治。无论运动的项目、强度或时间的长短如何,其肌肉所需的能量均来自三磷酸腺苷(ATP)的高能磷酸键(骨骼肌储存的磷酸肌酸用于瞬时的剧烈运动;肌细胞线粒体内的代谢产能来自肌糖原、动脉血所提供的葡萄糖、肌细胞和脂肪组织甘油三酯中的脂酸)。肌肉运动时的葡萄糖代谢可分为:一、在无氧酵解阶段,葡萄糖分解成中间产物丙酮酸,一部分再转化成乳酸,不需氧参与,1mol葡萄糖代谢只生成2mol ATP;二、在有氧氧化阶段,可产生大量ATP。丙酮酸
Exercise can cause the body to have a significant physical and biochemical changes, but also contribute to the prevention and treatment of cardiovascular disease. Irrespective of the duration of exercise, intensity or duration of exercise, the energy required for its muscles is derived from the high-energy phosphate bond of adenosine triphosphate (ATP) (stored in the skeletal muscle for transient strenuous exercise; metabolic capacity in muscle mitochondria From muscle glycogen, arterial blood glucose, muscle cells, and adipose tissue triglycerides). Glucose metabolism during muscle movement can be divided into: First, in the anaerobic glycolysis stage, the decomposition of glucose into pyruvate intermediate, part of the conversion into lactic acid, oxygen-free participation, 1mol glucose metabolism only generates 2mol ATP; Second, there are Oxygen oxidation stage, can produce large amounts of ATP. Pyruvate
