在短距离项目比赛中,起跑技术的好坏,直接影响着短跑成绩的优劣。然而,在短跑比赛中经常出现起跑时违例、犯规的现象。因此,不仅要教育学生充分认识到速度反应在起跑中的重要意义,还要对学生进行必要的心理训练。 一、造成起跑犯规的因素 (一)从生理角度和心理角度看,运动员听枪声后起跑是一种条件反射过程。整个反射过程是通过神经系统的活动来实现的。反射活动快慢取决于神经冲动通过反射弧的传导速度。可见,起跑的快慢主要与神经系统的灵活性有关,冲动传导越快,反映时就越短。
In the short distance competition, the starting technique is good or bad, which directly affects the quality of the sprint. However, there are often instances of irregularities and fouls at the start of the sprint race. Therefore, it is not only necessary to educate students to fully recognize the importance of speed response in starting a race, but also to provide students with the necessary psychological training. First, the starting foul factor (a) from a physiological point of view and psychological point of view, the athletes start shooting gunfire is a conditioned reflex process. The whole reflection process is through the activity of the nervous system. The speed of reflex activity depends on the rate of nerve impulses passing through the reflex arc. Can be seen that the speed of starting and the nervous system, mainly related to the faster the impulse conduction reflect the shorter.
