The objective of this study was to investigate the contribution of peripheral afferent input to the enhancement of isometric tremor during a sustained submaximal isometric contraction. It was hypothesised that during muscle fatigue, when excitatory drive is high, peripheral afferent input may augment oscillations in the stretch reflex arc and result in bursting motor-unit activity and increased tremor. Nine healthy subjects maintained isometric plantar flexions at 30% of their maximum voluntary… CONTINUE READING
