活化後增益作用（postactivaiton potentiation）近年來已經被大量地研究，許多研究已經指出活化後增益作用能在短時間之內提升動作表現。本文主要目的為介紹活化後增益作用的相關機制和探討有關活化後增益作用的相關文獻。一些文獻指出骨骼肌動態收縮和骨骼肌等長收縮皆可以產生活化後增益作用，然而，另外一些相關文獻則產生矛盾的結果。建議未來研究可以針對，受試者的類型、負重動作的處方、負重動作後的恢復時間、測試活化後增益作用的指標等因素，對活化後增益作用效益加以研究與探討。
Recently, postactivaiton potentiation has been widely studied. Numerous studies have indicated that postactivaiton potentiation can increase subsequent performance. The purpose of this paper was to discuss the physiological mechanism and evidence of postactivaiton potentiation. Some of the previous studies indicated that dynamic and isometric contraction of the skeletal muscles can induce postactivaiton potentiation. However, the others have yielded conflicting results. Further studies were needed to examine the issues including the effect of different factors (athlete's training status, prescription of the loading exercise, recovery time, and assessing method of postactivaiton potentiation) on postactivaiton potentiation benefit.
