Home Run Derby Participation in Major League Baseball Players: Is There Associated Injury Risk and Impact on Second-Half Performance?
Background: The Major League Baseball (MLB) All-Star Game (ASG) Home Run Derby (HRD) remains a highly anticipated event, during which contestants can take hundreds of maximum-effort swings en route to hitting a multitude of home runs. Critics have openly questioned the risk-benefit of HRD participation as it pertains to injury, alterations in swing mechanics, and timing. Purpose: To determine whether participation in the MLB ASG HRD was associated with both increased injury risk and decline in second-half performance in MLB players. Study Design: Cohort study; Level of evidence, 3. Methods: MLB players who participated in the HRD between 2006 and 2019 were identified through publicly available internet databases. A control group of ASG participants who had the highest home run totals in the first half of the corresponding MLB season were selected as a control group. Multivariable linear regression was used to determine independent associations between HRD participation and batting metrics in the second half of the season. Multivariable logistic regression also assessed the impact of HRD participation on injured list placement during the second half of the concurrent MLB season. Results: A total of 114 HRD participants and 114 ASG participant controls competed during the study period. No statistically significant differences were seen in batting metrics in the second half of the MLB season between HRD participants and ASG controls, although HRD participants had a significantly lower wins-above-replacement statistic for the season compared with controls (4.69 ± 2.06 vs 5.33 ± 2.08; P = .021). HRD participation was not significantly associated with injury during the second half. The number of HRD rounds in which a player participated did not result in a statistically significant increased odds of injury during the second half of the MLB season. Conclusion: HRD participants did not have increased odds of being placed on the injured list during the second half of the MLB season compared with controls, nor did they experience second-half performance declines in offensive production versus controls when multivariable linear regression analysis was performed.

机译：背景：主要联盟棒球（MLB）全明星游戏（ASG）Home Run Derby（HRD）仍然是一个高度预期的活动，在此期间，参赛者可以花费数百个最大努力的摇摆，以抵达众多家庭运行。批评者公开质疑HRD参与的风险效益，因为它涉及伤害，摆动力学和时序的变化。目的：确定参与MLB ASG HRD是否与MLB玩家中的伤害风险增加和下半年性能下降有关。研究设计：队列研究;证据级别，3.方法：通过公开可用的互联网数据库确定参加2006年至2019年的HRD的MLB玩家。选择了在相应的MLB季节的上半年最高的家庭运行总计的ASG参与者的控制组被选为对照组。多变量线性回归用于确定本赛季下半年HRD参与和击球指标之间的独立关联。多变量的逻辑回归还评估了HRD参与在并发MLB季节的下半年期间受伤名单安置的影响。结果：在研究期间，共有114名HRD参与者和114名ASG参与者控制。在HRD参与者和ASG控制之间的MLB季节的下半年的击球度量中没有看到统计学意义的差异，尽管HRD参与者与对照组的赛季的替代胜利胜利显着降低了（4.69±2.06 Vs 5.33± 2.08; p = .021）。 HRD参与在下半年期间与伤害没有显着相关。玩家参与的HRD轮数未导致MLB季节的下半部分在统计上显着增加的伤害的几率。结论：HRD参与者在MLB季节的下半年与对照组的下半年持续下半年没有增加的几率，并且当进行多变量线性回归分析时，它们也没有经历进攻性生产的下半年性能下降。
