推铅球是一项以力量为基础以速度为核心的速度力量型项目。也就是说,推铅球要求力量和速度和谐统一,完美结合。研究认为,推铅球作为一种需要最大力量和快速力量完美结合的田径项目,运动员支撑腿膝关节屈伸肌肉的最大力量和快速力量的有效发展对提高专项运动成绩有着关键的作用。从运动生物力学角度看,铅球出手瞬间初速度的取得依靠的是力量在最短时间内的爆发,也就是运动员所具备的爆发力,而不是单纯的力量。通过实验 Shot putting is a force-based speed-centric speed-force project. In other words, pushing the shot put the power and speed of harmony and unity, the perfect combination. The research shows that, as a track and field project that requires maximum combination of strength and rapid strength, the maximum strength and quick strength of athlete’s supporting knee flexion and extension muscles play a key role in improving special sports performance. From the point of view of sports biomechanics, the initial speed of shot put shot depends on the outbreak of power in the shortest time, that is, the explosive power of athletes rather than pure strength. through experiments
