Conforti, CM, HBA, Crotin, RL, RSCC, C, and Oseguera, J. An analysis of playoff performance declines in Major League Baseball. J Strength Cond Res 35(12S): S36-S41, 2021-At present, it is unknown how athletes of varying talent in Major League Baseball (MLB) perform in the postseason as compared with the regular season. Anecdotal evidence from the authors' previous work experience in MLB established the hypothesis that players of higher caliber were expected to perform worse in the playoffs compared with lesser talented cohorts. Publicly available data on 1477 MLB players from 1994 to 2019 were used to separate athletes into excellent, above average, average, and below average pitching, hitting, and defensive groups with respect to Fielding Independent Pitching (FIP), Weighted Runs Created Plus (wRC+), and Errors per Inning Out (EpIO), respectively. Mixed-model analyses of variance with Tukey's Honest Significant Difference post hoc testing was used to determine whether the change in performance was significant within groups at an a priori alpha level of p < 0.05. Within-subject effects' tests were statistically significant within regular season talent groups for FIP, wRC+, and EpIO in comparison with their playoff performance (p < 0.001). Excellent performers suffered most with more than half depreciating in playoff hitting (58%) and pitching performance (52%), yet nearly 80% of 908 fielders retained defensive ability, which was unexpected. Results indicate that teams should consider providing greater mental performance support, implement periodization strategies to taper or lower training workloads, offer team support networks, and anxiety desensitization for excellent MLB performers in approach of the playoffs, as certain aspects of pitching and hitting significantly suffer.
康福特、HBA、克罗廷、RL、RSCC、C 和奥塞格拉,J. 美国职棒大联盟季后赛表现下滑的分析。J 力量与调节研究 35(12S):S36-S41,2021-目前,尚不清楚美国职棒大联盟(MLB)中不同天赋的运动员在季后赛中的表现与常规赛相比如何。作者之前在 MLB 的工作经验中的轶事证据确立了这样一个假设,即与低天赋的球员相比,更高水平的球员预计在季后赛中的表现更差。1994 年至 2019 年,从 1477 名 MLB 球员中获得了公开可用的数据,根据独立投球得分(FIP)、加权跑得分加(wRC+)和每局失误(EpIO),将运动员分别分为优秀、高于平均水平、平均水平和低于平均水平的投手、击球手和防守者群体。使用混合模型方差分析和 Tukey 的诚实显着差异事后检验来确定在预先设定的 p < 0.05 的显着性水平内,组内的性能变化是否显着。与季后赛表现相比,在常规赛天赋组内,FIP、wRC+和 EpIO 的个体内效应测试具有统计学意义(p < 0.001)。优秀的投手表现下滑最严重,超过一半的投手在季后赛中的击球(58%)和投球表现(52%)下滑,而近 80%的 908 名外野手保持了防守能力,这是出乎意料的。结果表明,在季后赛临近时,球队应该考虑为优秀的 MLB 球员提供更大的心理表现支持,实施阶段性策略以减少或降低训练工作量,提供团队支持网络,并进行焦虑脱敏,因为投球和击球的某些方面会受到严重影响。
