中距离跑的运动能力

Motional Ability of Middle-distance Running

本刊今年第一期的一则补白《耐力项目中的肌肉能力》,摘编时限于篇幅,删节较多,不连贯,显得不完整、不严谨,以至读者产生了一些疑问.现请吕望山先生作一简要的解答.

The motional ability of middle-distance running not only depends on the motional ability of muscles, but also relates closely to the functions of nerves, heart, as well as the intelligence, pschological fitness, environmental and social factors.The tactical arrangements in running rest mainlyin changing running speed of different distance because it is controlled by the central nervous system, and in particular, the brain.The contraction ability of muscle fibres is related to the contents and intensity of trainning.
