In a previous retrospective study, base sliding was found to be responsible for 71% of recreational softball injuries. As most injuries occurred following rapid deceleration impact against stationary bases, quick-release (breakaway) bases were evaluated as a means to modify this mechanism of injury. Six hundred thirty-three softball games were played on breakaway-base fields and 627 games were played on stationary-base fields. Forty-five sliding injuries (7%) occurred on the stationary-base diamonds and only two sliding injuries (less than 1%) occurred on the breakaway-base fields. Implementing the use of breakaway bases in recreational softball leagues could potentially achieve a significant, cost-effective reduction of injuries.
在之前的一项回顾性研究中，发现垒基滑动是娱乐性垒球运动中71%的损伤的原因。由于大多数损伤发生在对固定垒基的快速减速撞击之后，因此对快拆（可分离）垒基进行了评估，将其作为一种改变这种损伤机制的方法。在使用可分离垒基的场地进行了633场垒球比赛，在使用固定垒基的场地进行了627场比赛。在使用固定垒基的菱形场地发生了45起滑动损伤（7%），而在使用可分离垒基的场地仅发生了2起滑动损伤（不到1%）。在娱乐性垒球联盟中使用可分离垒基有可能显著且经济高效地减少损伤。
