一、传统测量方法根据《田径竞赛规则》高度跳跃的要求:所有测量应以厘米为单位,从地面垂直至横杆上沿最低点;每次升高横杆后,在运动员试跳之前均应测量横杆高度;横杆高度测量后,如横杆曾被触及,裁判员在每次后继试跳之前,必须再次审核测量。在实际的测量操作中,一般都要反复校正:根据升高高度计划,先在横杆的中央测量出一个标准高度,再在横杆两端测量一个比标准高度稍高一点的高度,然后再观察整根横杆是否平衡等。按照这样的测量方法,每一次大概需要3分钟左右,且测量出来的成绩误差较大。
First, the traditional measurement method According to “track and field competition rules” height jumping requirements: All measurements should be in centimeters, from the ground vertical to the bar along the lowest point; each time after raising the bar, before the athletes try to jump should be Measure the height of the bar; after the bar height is measured, if the bar has been touched, the referee must review the measurement again before each subsequent jump test. In actual measurement operations, the calibration is usually repeated: According to the plan of increasing the height, measure a standard height at the center of the horizontal bar first, and then measure a height slightly higher than the standard height at both ends of the horizontal bar Observe whether the entire crossbar balance. According to such a measurement method, each time takes about 3 minutes or so, and the measurement error is relatively large.
