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.
随着年龄增长，快速、持续的拉伸-缩短收缩（SSC）所导致的肌肉损伤会持续更长时间，并且对中等速度、间歇性SSC的适应不良更为常见。我们推测，炎症信号和氧化应激的高基线水平可能是这些结果的基础，而精心调整高强度SSC训练设计可重置基础条件，并使肌肉适应SSC。
