对完成相同运动负荷的不同运动员,测定他们的能量需要量,发现差别很大,不同运动员做同样的功所消耗的能量是不一样的。要提高运动技术经济性,消耗最少的力量完成准确的动作,必须掌握熟练的技术、消除任何多余的动作、减少外界阻力(如游泳中采用较好的流线型姿势)、减少每周期速度波动 For different athletes who perform the same exercise load, their energy requirements are measured and found to vary widely. The energy used by different athletes to do the same work is different. To improve the technical and economic performance of sports, and to consume the least amount of power to perform accurate actions, you must master skilled techniques to eliminate any unnecessary movement and reduce external resistance (such as using better streamlined posture in swimming) and reduce the rate fluctuations per cycle
