骨骼肌纤维类型和肌纤维蛋白同功型的多样性 ,以及在不同肌组织的特定分布和构成比例 ,决定其复杂的适应能力。骨骼肌纤维类型的转变及其与Ca2 +-ATPase酶活性和运动能力、动作结构的关系的研究 ,为运动训练和运动选材提供了理论基础。 The diversity of skeletal muscle fiber type and muscle fiber protein isomorphism, as well as the specific distribution and composition ratio in different muscle tissues, determines its complex adaptability. The change of skeletal muscle fiber type and its relationship with Ca2 + -ATPase activity, exercise capacity and movement structure provide the theoretical basis for exercise training and sports selection.
