Eight women triple jump finalists at the 1986 Big Ten Track and Field Championships and 10 women triple jump finalists at the 1986 National Track and Field Competition were filmed during competition. Among selected kinematic characteristics, the following high correlations (r greater than 0.70) were found: the distance of the hop phase correlated highly with the total jump distance; the horizontal position of the center of gravity of the body in relation to the support foot at takeoff correlated highly with the distance of the hop and the jump phases; the horizontal velocity into the step phase correlated highly with the total distance of the jump; the vertical velocity into the hop and step phases correlated highly with the respective phase distance; and there was an inverse correlation between the maximum height of the center of gravity during the flight phase of the step and the total distance. A significant difference was found between men and women triple jumpers in relation to the contribution of the step phase to the total distance of the jump (men, means = 29.5, SD = 1.46; women, means = 26.7, SD = 2.94; P less than 0.05). All remaining relationships among the kinematic variables studied were found to be not significant at P less than 0.05 or were less than r = 0.70. The phase ratios of current women triple jumpers were similar to ratios that have been reported for the novice athlete.
在1986年十大联盟田径锦标赛的8名女子三级跳远决赛选手以及1986年全国田径比赛的10名女子三级跳远决赛选手比赛期间进行了拍摄。在选定的运动学特征中，发现了以下高度相关性（r大于0.70）：单脚跳阶段的距离与总跳跃距离高度相关；起跳时身体重心相对于支撑脚的水平位置与单脚跳和跳跃阶段的距离高度相关；进入跨步阶段的水平速度与跳跃的总距离高度相关；进入单脚跳和跨步阶段的垂直速度与各自阶段的距离高度相关；并且在跨步阶段飞行期间重心的最大高度与总距离之间存在负相关。在三级跳远运动员中，发现男子和女子在跨步阶段对跳跃总距离的贡献方面存在显著差异（男子，均值 = 29.5，标准差 = 1.46；女子，均值 = 26.7，标准差 = 2.94；P小于0.05）。在所研究的运动学变量之间的所有其余关系在P小于0.05时被发现不显著或小于r = 0.70。当前女子三级跳远运动员的阶段比例与已报道的新手运动员的比例相似。
