短跑与物理学中的运动学有着密切的、不可分割的关系,其中许多训练原理都可以利用物理学知识来分析,尤其对速度概念的掌握,对训练有一定的促进作用。在研究中,我们将物理学与短跑运动员速度型抗阻力跑训练有机结合起来,希望能使短跑训练更加科学化、规范化,并进一步推广物理学的应用。一、利用力学及动量观点分析抗阻力跑训练1.利用牛顿第二定律分析如何提高抗阻力跑的速度高中物理学习中,我们已经学习过牛顿第二定律,几乎所有学生都知道牛顿第二定律的核心是F一
Sprint has a close and inseparable relationship with the kinematics in physics. Many of the training principles can be analyzed by using the knowledge of physics. In particular, the mastery of the speed concept can promote the training. In the research, we combine physics with sprint athlete’s speed type anti-resistance running training, hoping to make sprint training more scientific and standardized, and to further popularize the application of physics. First, the use of mechanics and momentum point of view analysis of anti-resistance training 1. The use of Newton’s second law to analyze how to improve anti-resistance running speed Physics study, we have learned Newton’s second law, almost all students are aware of Newton’s second law The core is F a
