一、挖掘短跑的生物适应价值短跑练习能提高人的心肺功能,增强心脏的工作能力,增加肺活量,改善体质健康状况和人体运动系统、内脏器官和神经系统的功能,增强人体的免疫力。挖掘策略:速度训练(反应、位移速度);力量训练(负重、跳跃、抗阻力);耐力训练(往返跑、变速跑、间歇跑、越野跑、定时跑);柔韧性训练(韧带、肌肉伸展性)。二、挖掘短跑的运动行为价值1.身体素质。通过短跑练习可提高学生的速度、力量、协调性、灵敏性、反应力、爆发力等;2.技术动作。通过短跑的练习,增强上下肢协调配合、发展学生决速启动
First, excavation sprint biological adaptation value Sprint practice can improve people’s heart and lung function, enhance heart ability to work, increase lung capacity, improve physical and mental health and human exercise system, internal organs and nervous system functions, enhance the body’s immunity. Mining strategy: speed training (reaction, displacement speed); strength training (load, jump, resistance); endurance training (round trip, variable speed running, intermittent running, cross country running, regular running); flexibility training Sex). Second, excavation sprint sports value 1. Physical fitness. Sprint practice can improve the speed, strength, coordination, sensitivity, reaction, explosive, etc .; 2 technical action. Through the sprint practice, enhance the coordination of upper and lower limbs, the development of students speed start
