ABSTRACT

The Movement Specific Reinvestment Scale (MSRS) is used to quantify differences in the propensity that individuals have to consciously engage in movement. Although the MSRS is widely used in movement science, evidence for its theoretically negative association with motor performance remains inconsistent. The aim of this meta-analysis was to summarize research findings between scores on the MSRS and motor performance, and to disentangle theoretical and sampling factors that may moderate the relationship. Following PRISMA guidelines, Web of Science, ProQuest, Google Scholar, PsychInfo and PubMed were searched. Out of the eligible texts, 410 effect sizes from 29 studies were extracted. Multi-level meta-analysis indicated that neither the MSRS total score, nor the MSRS subscales score (Movement Self-Consciousness and Conscious Motor Processing), were significantly associated with motor performance. However, the MSRS total score was significantly and negatively associated with motor performance when either (1) psychological pressure was present, (2) motor performance involved object manipulation, or (3) speed was the outcome unit of motor performance. In conclusion, the MSRS total score was linked to movement failure in certain motor conditions, providing partial support for the central tenet of the Theory of Reinvestment that a propensity for conscious engagement in movement can impair motor performance.

摘要

运动特定再投资量表（MSRS）用于量化个人有意识地参与运动的倾向差异。尽管 MSRS 广泛应用于运动科学，但其理论上与运动表现负相关的证据仍然不一致。本荟萃分析的目的是总结 MSRS 分数与运动表现之间的研究结果，并理清可能调节这种关系的理论和抽样因素。遵循 PRISMA 指南，检索了 Web of Science、ProQuest、Google Scholar、PsychInfo 和 PubMed。从符合条件的文本中，提取了 29 项研究的 410 个效应值。多层次荟萃分析表明，无论是 MSRS 总分还是 MSRS 子量表分数（运动自我意识和意识运动处理），与运动表现显着相关。然而，当（1）存在心理压力，（2）运动表现涉及物体操作，或（3）速度是运动表现的结果单位时，MSRS总分与运动表现显着负相关。总之，MSRS 总分与某些运动条件下的运动失败有关，这为再投资理论的中心原则提供了部分支持，即有意识地参与运动的倾向会损害运动表现。(3)速度是运动表现的结果单位。总之，MSRS 总分与某些运动条件下的运动失败有关，这为再投资理论的中心原则提供了部分支持，即有意识地参与运动的倾向会损害运动表现。(3)速度是运动表现的结果单位。总之，MSRS 总分与某些运动条件下的运动失败有关，这为再投资理论的中心原则提供了部分支持，即有意识地参与运动的倾向会损害运动表现。
