跳高是由伸膝、髋、躯干肌群和屈足肌群爆发性收缩完成的。发展跳高能力的关键在于肌肉用力时做到爆发有力,它的用力性质属于速度力量,也称爆发力。爆发力的大小取决于肌肉快速收缩时的力量和速度,所以发展学生跳高的能力,应与提高有关肌肉群的力 High jump by knee extension, hip, trunk muscle and flexor muscle group completed the explosive contraction. The key to the development of high jump ability to do when the muscle force burst out of force, its force is the nature of the speed of force, also known as explosive force. The size of the explosive force depends on the strength and speed of muscle contraction rapidly, so the ability to develop high jump should be related to the improvement of muscle group strength
