在生物力学方面,教练员应主要关心两个问题:减少和阻止阻力;提高力的产生。阻力是提高运动成绩的最大限制因素。这是因为随着游速提高一个单位,阻力会以4倍的速率增加。这不成比例的增加最终决定了一个人的游速。在运动员训练的早期,教授正确的技术动作以便将阻力减少到最小程 In biomechanics, coaches should focus primarily on two issues: reducing and deterring resistance; and increasing their power. Resistance is the biggest limiting factor in improving athletic performance. This is because as the speed increases by one unit, resistance increases at 4 times. This disproportionate increase ultimately determines a person’s speed. Early in the training of athletes, teach the correct technical action in order to reduce the resistance to a minimum
