摘　　要：利用现代的光电技术研制了VJ-I型光电纵跳仪,该仪器主要由光电开关、控制电路、计时装置和高度计算4部分组成,可以方便、可靠地测出纵跳的高度,作为评价人体弹跳能力的重要指标。同时,利用该仪器对纵跳高度的实测也客观地反映出摆臂、缓冲对起跳的重要意义,以及动作不连贯对起跳效果的影响。Adopted modem technique of photo electricity, the VJ-Ⅰ Photo Electricity Vertical Jump Instrument was developed, which consists of photo electricity switch, control electrocircuit, time instrument and height computing. It can measure the height of vertical jump conveniently and credibly to evaluate the ability of jump. Simultaneously, in the measurement of height of various modes of vertical jump it indicated the important significance of swing limb and cushion to vertical jump, and bad influence of not fluent act.
