运用音响助跑节奏模式进行跳远助跑训练的实验研究

从控制训练的角度出发,为跳远运动员建立一种可随时调整的音响助跑节奏模式.经过8周训练实验,分别对实验前后实验组和对照组的助跑节奏、速度、水平速度利用率、准确性及运动成绩等进行了统计处理;并对助跑后两步及起跳技术的影片进行了解析,对组间、组内的差异进行了检验.结果表明:采用音响助跑节奏模式进行训练,能够明显地提高跳远运动员的训练效益.

Experimental Study on Approach Training in Long Jump with Acoustic Rhythm Model

From the angle of controlling the training, an adjustable acoustic rhythm model was established for approach training of long jumpers. Statistic analysis was made before and after 8 week training-on the rhythm, speed, utilization ratio of horizontal speed, accuracy of approach and the performance between experimental and control groups. Film of the last two steps and take-off was analysed and intragroup and intergroup differences were tested. Results indicated that training with acoustic rhgthm model may significantly improve the efficency of training.
