Residual force enhancement (rFE), defined as increased isometric force following active lengthening compared to a fixed-end isometric contraction at the same muscle length and level of activation, is present across all scales of muscle. While rFE is always present at the cellular level, often rFE “non-responders” are observed during joint-level voluntary contractions.

在人类中，当从单个肌肉纤维缩放到关节水平时，残余力增强会减少


残余力增强 （rFE），定义为在相同的肌肉长度和激活水平下，与固定端等长收缩相比，主动延长后等长力增加，存在于所有肌肉尺度上。虽然 rFE 始终存在于细胞水平，但通常在关节水平自主收缩期间观察到 rFE“无反应者”。
