短跑途中跑技术诊断与调控

Diagnosis, Regulation and Control of Running Skills during the Course of Sprint

使用M90 0型录像机 (5 0桢 /s)拍录研究对象训练前后 10 0m途中跑技术 ;对录像资料采用”爱捷录像解析仪”进行解析 ;对数字化信息进行有关统计学处理 ;对训练结果进行分析。结果表明 :1)受试者百米途中跑技术诊断的客观性 ,是选择正确训练调控系统的先决条件。 2 )在训练中 ,高校运动员思想、情绪和表现等多方面信息 ,是教练员选择对策调整计划 ,控制训练过程的依据。 3)在训练调控中 ,教练员应重视严要求的同时 ,不可忽视创造轻松的训练氛围。 4 )教练员应关注管理、控制的时机 ,既要使运动员保持适度的兴奋性 。

The subjects' running skills during the course of the 100m.sprint were videoed before and after training with the help of a M900 video camera. The video materials were analyzed and the digital information was processed statistically. By analyzing the training results it was indicated: 1. The objectivity of diagnosing the running skills during the course of the 100 m. sprint is the precondition of choosing a correct system for training regulation and control; 2. During training, the information of the athletes in colleges and universities, such as thinking, emotion and performance is the basis for coaches to choose measures, modulate plans and control the training process; 3. In terms of training regulation and control, besides being strict with the athletes, coaches cannot ignore a relaxed atmosphere for training; 4. Coaches should pay attention to the management and control opportunities, so that the athletes can either keep their moderate excitability, or avoid injuries due to the lose of control.
