Abstract
Age alters the control of voluntary movement. A frequently observed adaptation is the increased agonist and antagonist muscle coactivation. Here we examine the evidence for spinal circuits mediating this change in motor behavior and propose the hypothesis that cortical mechanisms also contribute to this age-associated change in muscle coactivation.
摘要
年龄会改变对随意运动的控制。一种常见的适应性变化是主动肌和拮抗肌的共同激活增加。在此，我们研究介导这种运动行为变化的脊髓回路的证据，并提出假说，即皮层机制也促成了这种与年龄相关的肌肉共同激活变化。
