俄罗斯专家研制成一种电脑游泳训练仪。该仪器由一台微电脑和它控制的一束设于水下或挂在泳道上空的灯光指示信号线所组成。教练员可通过训练仪的键盘输入游泳距离、游速、重复次数、间隙时间、运动员分组数等各种与训练有关的数据。仪器启动后可发出音响代替教练的口令,运动员下水后便可在灯光信号的指引下完成教练员规定的训练计划。 Russian experts developed into a computer swimming training device. The instrument consists of a microcomputer and a bunch of light-control signal lines that are under water or hanging over the lane. Trainers can enter various training-related data such as swimming distance, speed, number of repetitions, gap time, number of athletes, etc. through the keyboard of the trainer. After the instrument is activated, the audible signal may be sent to replace the coach’s password. After the athlete launches, the coach can complete the training plan under the guidance of the light signal.
