Abstract

Abstract : With aging, muscle injury from rapid, continuous stretch-shortening contractions (SSC) is prolonged, and maladaptation to moderate-velocity, intermittent SSC is more common. We hypothesize that high baseline levels of inflammatory signaling and oxidative stress may underlie these outcomes, whereas careful modulation of high-intensity SSC training design resets basal conditions and permits muscle adaptation to SSC. Abstract : With aging, oxidative stress/inflammation is elevated chronically and during muscle maladaptation/injury. Appropriate stretch-shortening contraction training improves basal conditions and adaptation.
