摘要
从代谢关键酶和代谢底物两方面综述了大强度训练对ATP/CP代谢的影响。大强度训练对CK活性的影响存在着争议,但高水平的运动员能够更快地动用CP;大强度训练在一定程度上可以提高MK活性;大强度训练对肌凝蛋白Ca2+-ATP酶活性的影响不确定,多数学者认为不会改变其安静时水平,但会影响运动时所能达到的最大ATP酶活性。大强度运动时,几乎所有类型肌纤维中的CP都参与供能,而ATP供能主要发生在Ⅱ型肌纤维。大强度训练对安静时ATP/CP含量影响不大,但是非常大强度、大运动量的训练可能会引起ATP少许减少;运动训练可以增加线粒体ATP生成速率;大强度运动中TAN代谢与肌纤维类型有关,主要发生在Ⅱ型肌纤维。
This paper summarizes the effect that high intensity training has on ATP/CP from metabolic key enzymes and metabolic substrate. There is a dispute on the effect that high intensity training has on CK activity. However, high-level athletes could make use of CP faster. High intensity training could improve MK activity in a certain sense. The effect that high intensity training has on myosin Ca^2 ＋ -ATPase activity is uncertain. Most scholars think that high intensity training will not change its still state level, but has an influence on the maximum ATPase activity during doing exercise. When people do high intensity training, CP in almost all type of muscle fibers take part in energy supply. However, ATP energy supply mainly happens in type Ⅱ fibers. High intensity training has not great effect on the quantity of ATP/CP during its still state, but very high intensity training perhaps causes the drop of ATP. Athletic training may increase mitochondrial ATP production rate. TAN metabolism in high intensity training relates to the kind of muscle fibers, and mainly happens in type Ⅱ fibers.
