Two basic baseball sliding techniques, feet-first and head-first, are taught at all levels of play. Because of the risk for injury to the upper extremities and the cervical spine during head-first sliding, it is potentially more dangerous than feet-first sliding. There is an assumption among coaches that head-first sliding is more aggressive and faster, but there has been no scientific study to prove this claim.
The purpose of this study was to determine which technique provides a faster slide into the base.
Controlled field study.
A total of 60 players ranging from Little League to college level was analyzed. Each athlete was evaluated three times from a standing start at first base to either a head-first or feet-first touch of second base. Each athlete was also timed in a 40-yard sprint and his or her preferred sliding technique was recorded.
We found no statistically significant difference in speed between head-first and feet-first sliding at all levels of play in this study.
在各级棒球比赛中都教授两种基本的滑垒技术，即脚先着地滑垒和头先着地滑垒。由于头先着地滑垒时上肢和颈椎受伤的风险，它可能比脚先着地滑垒更危险。教练们有一种假设，认为头先着地滑垒更具攻击性且速度更快，但尚无科学研究能证明这一说法。
本研究的目的是确定哪种技术能使滑向垒包的速度更快。
对照现场研究。
共分析了60名从小联盟到大学水平的球员。每位运动员从一垒站立起跑，分别以头先着地或脚先着地的方式触碰到二垒，进行三次评估。每位运动员还进行了40码短跑计时，并记录其偏好的滑垒技术。
在本研究中，我们发现在各级比赛中，头先着地滑垒和脚先着地滑垒的速度在统计学上没有显著差异。
