探讨不同的训练手段,对提高短跑运动员的成绩十分重要,目前400米跑的运动成绩不太理想,有的认为是由于跑的过程中技术不太合理;有的认为是跑的绝对速度不快;也有的认为是速度耐力较差。为此我们在82年冬训期间对省短跑组4名男运动员进行了不同训练手段的血乳酸的观察,其目是探讨和寻找发展速度耐力的有效手段,供教练员参考。一、观察对象和方法: Discussion of different training methods is very important to improve the performance of the sprinter. At present, the performance of the 400-meter race is not ideal. Some think it is because the technology in the running is not very reasonable. Some people think that running is absolutely unpleasant. Others think speed endurance is poor. To this end, during the winter training period of 82 years, we observed the blood lactate of 4 male athletes in the provincial sprint group for different training methods. The purpose of this study is to explore and find effective means to develop speed endurance for the trainers’ reference. First, observe the object and method:
