在击球工具和球之间的碰撞中，术语“甜蜜点”表示产生最佳结果的撞击位置。在足球踢球中，不知道是否在脚上存在甜蜜点，因为不存在测量三维空间中的撞击位置的方法。因此，目的是：（1）开发一种在三维空间中测量足部撞击位置的方法;（2）确定运动员是否以特定位置撞击球;（3）确定撞击位置与踢球性能之间的关系;（4）讨论足部是否存在甜蜜点。对10名球员进行了30次澳大利亚足球落踢的足球冲击特征进行了个体内分析。(1)提出并验证了一种测量撞击位置的方法。(2)撞击位置呈正态分布，Shapiro-Wilk检验的结果不显著（p > 0.05），直方图检验也证明了这一点，这意味着球员的目标是脚上的一个位置。(3)撞击位置影响足球能量传递、球飞行轨迹和踝关节跖/背屈。(4)这些结果表明，澳大利亚足球落球踢脚上存在一个甜蜜点。总之，撞击位置是一个重要的撞击特征。
ABSTRACT In the collision between a striking implement and ball, the term “sweet spot” represents the impact location producing best results. In football kicking, it is not known if a sweet spot exists on the foot because no method to measure impact location in three-dimensional space exists. Therefore, the aims were: (1) develop a method to measure impact location on the foot in three-dimensional space; (2) determine if players impacted the ball with a particular location; (3) determine the relationship between impact location with kick performance; (4) discuss if a sweet spot exists on the foot. An intra-individual analysis was performed on foot-ball impact characteristics of ten players performing 30 Australian football drop punt kicks toward a target. (1) A method to measure impact location was developed and validated. (2) The impact locations were normally distributed, evidenced by non-significant results of the Shapiro-Wilk test (p > 0.05) and inspection of histograms, meaning players targeted a location on their foot. (3) Impact location influenced foot-ball energy transfer, ball flight trajectory and ankle plantar/dorsal flexion. (4) These results indicate a sweet spot exists on the foot for the Australian football drop punt kick. In conclusion, the impact location is an important impact characteristic.
