Prolonged low-frequency force depression (PLFFD) is an intramuscular phenomenon involving the slow recovery of submaximal muscle strength following strenuous exercise. We hypothesize that the contribution of impaired excitation-contraction coupling processes to PLFFD is task dependent, and that they will be different between metabolically and mechanically demanding exercises. We also discuss evidence of the effectiveness of interventions to mitigate PLFFD.
长时间低频力量抑制(PLFFD)是一种肌肉内现象,涉及剧烈运动后次最大肌肉力量的缓慢恢复。我们假设,兴奋 - 收缩偶联过程受损对PLFFD的影响取决于任务,并且在代谢需求和机械需求的运动之间会有所不同。我们还讨论了减轻PLFFD的干预措施有效性的证据。
