To determine if the use of the Hollywood Impact Base would significantly reduce the frequency of sliding and base-running injuries to baseball and softball players, we recorded injury information for several teams who used these bases and standard stationary bases. The investigators, under the direction of the Central Michigan University team physician, verified each recorded incident by contacting the injured participant. The sample included interscholastic, intercollegiate, recreational, and intramural softball and baseball teams. There were 33,153 athlete-exposures with the Hollywood Impact Base in use and 3999 with the standard stationary base over a 2-year period (1990 and 1991). There were four injuries that could be directly attributed to the standard stationary base and only one injury that could be attributed to the Hollywood Impact Base. The results (t = -1.94, P < 0.05) verify that using the Hollywood Impact Base significantly reduced the frequency of sliding and base-running injuries. The Hollywood Impact Base injury rate of 0.08% per game compares favorably with the reported breakaway base injury rate. The results of our study verify that the Hollywood Impact Base is similarly effective in reducing the risk of base-related injuries.
为了确定使用好莱坞撞击式垒垫是否会显著降低棒球和垒球运动员滑倒及跑垒受伤的频率，我们记录了几支使用这些垒垫和标准固定垒垫的球队的受伤信息。调查人员在中密歇根大学队医的指导下，通过联系受伤参与者核实了每起记录在案的事件。样本包括校际、大学间、娱乐性和校内垒球及棒球队。在1990年和1991年的两年期间，使用好莱坞撞击式垒垫时有33153人次运动员暴露，使用标准固定垒垫时有3999人次。有四起受伤可直接归因于标准固定垒垫，而只有一起受伤可归因于好莱坞撞击式垒垫。结果（t = -1.94，P < 0.05）证实，使用好莱坞撞击式垒垫显著降低了滑倒和跑垒受伤的频率。好莱坞撞击式垒垫每场比赛0.08%的受伤率与报道的可脱离式垒垫受伤率相比很有利。我们的研究结果证实，好莱坞撞击式垒垫在降低与垒垫相关的受伤风险方面同样有效。
