不同距离全速跑后血乳酸的对比与分析

Comparison and Analysis of Blood Lactate after Different Distance Sprint

为研究100m、400m、800m和1 500m4种不同距离全速跑后血乳酸的变化,选取9名志愿者参与实验。结果表明,4种距离全速跑后血乳酸值受主要能量供应系统、运动负荷强度以及运动持续时间的影响;不同距离负荷后的血乳酸值比运动前有明显增加,在不同距离项目之间血乳酸值呈现一定差别,表现在血乳酸含量随运动强度和运动持续时间的增加而增加。根据这种特点可以利用血乳酸评定运动负荷强度以及科学指导训练提供重要的参考依据。

To study 100m, 400m, 800m and 1 500m four different variation of blood lactate after full throttle from selected nine volunteers participated in the experiment , experimental results show that the four distances affect full throttle after the main energy supply system , exercise load intensity and exercise duration by blood lactate values. Blood lactate values at different distances after the load have increased significantly over the previous motion. The distance between the different projects of blood lactate values show some differences. The performance of blood lactate concentration increases with increasing exercise intensity and exercise duration in .This feature is based on the theory that use of blood lactate can provide important reference for the assessment of Exercise Intensity and scientific guidance training.
