通过对动物进行积极的体力负荷实验,证明脂类过氧化物的氧化是与疲劳和随之而来的心肌损伤密切相关。本文对不同运动等级水平和不同组别的越野滑雪运动员血液中脂肪过氧化物的含量差异进行分析,以及评价这些差异的生理学意义。 By performing positive physical load experiments on animals, the oxidation of lipid peroxides is shown to be closely related to fatigue and subsequent myocardial damage. In this paper, the differences of blood lipid peroxidation in cross-country skiers with different exercise levels and different groups were analyzed, and the physiological significance of these differences were evaluated.
