在适当的实验数据，使用三维电影摄影方法产生的光，在跳高的背越式跳高技术所涉及的翻译的力学进行了检查。曲线助跑被发现会导致运动员在起跳阶段（TD）开始时向曲线中心倾斜。重心（c.g.）的跳跃者在TI时垂直速度为负）。重心轨迹的横向偏移。在起飞期间，噬菌体很小，这意味着向心力很小。初始轨迹的抛物线轨迹的重心。起飞后与水平面成40度至48度角。在起跳阶段，发现起跳腿的弯曲至少和以前报道的使用跨骑式的运动员一样多。研究中的一名受试者能够越过横杆，尽管他的重心所遵循的抛物线路径的峰值高度。和酒吧在同一水平线上
The mechanics of the translations involved in the Fosbury-flop technique of high jumping were examined in the light of appropriate experimental data, generated using a 3-dimensional cinematographical method. The curved run-up was found to cause the athletes to lean toward the center of the curve at the start of the take-off phage (TD). The center of gravity (c.g.) of all the jumpers had a negative vertical velocity at TI). The lateral deviation of the path of the c.g. during the take-off phage was small, implying small centripetal forces. The initial trajectory of the parabolic path of the c.g. after the take-off made an angle of between 40 degrees and 48 degrees with the horizontal plane. During the take-off phase the take-off leg was found to flex at least as much as previouslyreported for athletes using the straddle style. One of the subjects in the study was able to clear the bar although the peak height of the parabolic path followed by his c.g. was at the same level as the bar.
