The takeoff (= push-off) leg in jumping, handedness, and leg length inequality as measured radiographically were recorded for 892 young healthy subjects, 62 of whom were top-level athletic jumpers, 654 competetive athletes representing other sports, and 176 Finnish Army conscripts. Correlation between the laterality of takeoff leg and handedness was poor, but a significant majority (81.4% of jumpers, 65.1% of other athletes, and 76.8% of conscripts) invariably used the longer leg for takeoff. Incidence of leg length inequality was highest in the group of athletic jumpers, the difference between top-level jumpers and runners being statistically significant.
对892名年轻健康受试者记录了其在跳跃中的起跳（即蹬地）腿、利手以及通过X光测量的腿长差异，其中62人为顶级田径跳跃运动员，654人为其他项目的竞技运动员，176人为芬兰陆军新兵。起跳腿的偏侧性与利手之间的相关性较差，但绝大多数人（81.4%的跳跃运动员、65.1%的其他运动员和76.8%的新兵）总是用较长的腿起跳。腿长差异的发生率在田径跳跃运动员组中最高，顶级跳跃运动员和跑步运动员之间的差异具有统计学意义。
