It is widely accepted that sleep better facilitates the consolidation of motor memories than does a corresponding wake interval (King et al., 2017). However, no in-depth analysis of the various motor tasks and their relative sleep gain has been conducted so far. Therefore, the present meta-analysis considered 48 studies with a total of 53 sleep (n = 829) and 53 wake (n = 825) groups. An overall comparison between all sleep and wake groups resulted in a small effect for the relative sleep gain in motor memory consolidation (g = 0.43). While no subgroup differences were identified for differing designs, a small effect for the finger tapping task (g = 0.47) and a medium effect for the mirror tracing task (g = 0.62) were found. In summary, the meta-analysis substantiates that sleep generally benefits the consolidation of motor memories. However, to further our understanding of the mechanisms underlying this effect, examining certain task dimensions and their relative sleep gain would be a promising direction for future research.

与相应的唤醒间隔相比，睡眠更好地促进了运动记忆的巩固（King等，2017）。但是，到目前为止，尚未对各种运动任务及其相对睡眠增加进行深入分析。因此，本荟萃分析考虑了48个研究，总共有53个睡眠（n = 829）和53个觉醒（n = 825）组。所有睡眠和醒来组之间的总体比较对运动记忆巩固中的相对睡眠增益影响较小（g = 0.43）。同时，确定了不同的设计没有亚组差异，对于手指敲击任务（效果小克= 0.47）和用于跟踪镜任务的介质的效果（克= 0.62）。总而言之，荟萃分析证实，睡眠通常有益于运动记忆的巩固。但是，为了进一步了解这种作用的潜在机制，检查某些任务的大小及其相对的睡眠增加将是未来研究的有希望的方向。
