Neural aspects of human muscle fatigue

肌肉疲劳在健康人运动后很常见。在许多任务中，有些肌肉会比其他肌肉更疲劳。因此，神经系统必须经常协调疲劳的肌肉（产生较少的力量）和不疲劳的肌肉。我们将研究一块肌肉的疲劳如何改变大脑控制从事相同任务或不相关任务的其他肌肉的方式。这将有助于理解导致表现不佳和受伤的协调失败。

Muscle fatigue is common after exercise in healthy people. In many tasks, some muscles become more fatigued than others. Thus, the nervous system must often coordinate fatigued muscles (which produce less force) with unfatigued muscles. We will investigate how fatigue of one muscle alters the way the brain controls other muscles that are engaged in the same task or in unrelated tasks. This will aid understanding of the failures of coordination that lead to poor performance and injury.
