A systematic literature search was conducted to review the evidence of residual force enhancement (RFE) in vivo human muscle. The search, adhered to the PRISMA statement, of CINAHL, EBSCO, Embase, MEDLINE, and Scopus (inception-July 2017) was conducted. Full-text English articles that assessed at least 1 measure of RFE in vivo voluntarily contracted human skeletal muscle were selected. The methodologies of included articles were assessed against the Downs and Black checklist. Twenty-four studies were included (N = 424). Pooled Downs and Black scores ranked "fair" ([Formula: see text] [2.26]). RFE was observed in all muscles tested. Joint range of motion varied from 15° to 60°. Contraction intensities ranged from 10% to >95% maximum. Although transient force enhancement during the stretch phase may change with angular velocity, RFE in the subsequent isometric phase is independent of velocity. The magnitude of RFE was influenced by smaller stretch amplitudes and greatest at joint angles indicative of longer muscle lengths. Contraction and activation intensity influenced RFE, particularly during the initial isometric contraction phase of a poststretch isometric contraction. RFE resulted in increased torque production, reduced muscular activation, and enhanced torque production when the neuromuscular system is weakened seen in an aged population.
进行了一项系统的文献检索，以回顾体内人类肌肉中残余力增强（RFE）的证据。检索遵循PRISMA声明，对CINAHL、EBSCO、Embase、MEDLINE和Scopus（起始时间 - 2017年7月）进行了检索。选择了评估体内自愿收缩的人类骨骼肌中至少一项RFE指标的全文英文文章。根据唐斯和布莱克检查表对纳入文章的方法进行评估。纳入了24项研究（N = 424）。唐斯和布莱克综合评分等级为“中等”（[公式：见正文] [2.26]）。在所有测试的肌肉中均观察到RFE。关节活动范围从15°到60°不等。收缩强度范围从最大收缩力的10%到>95%。虽然拉伸阶段的瞬时力增强可能随角速度而变化，但随后等长收缩阶段的RFE与速度无关。RFE的大小受较小拉伸幅度的影响，并且在指示肌肉长度较长的关节角度处最大。收缩和激活强度影响RFE，特别是在拉伸后等长收缩的初始等长收缩阶段。RFE导致扭矩产生增加、肌肉激活减少，并且在老年人群中观察到的神经肌肉系统减弱时增强扭矩产生。
