Pre-movement antagonist muscle co-activation is related to worse performance in elderly persons Vrije Universiteit Brussel
Purpose: Multiple causes contribute to the prolonged reaction-times (RT) observed in elderly persons. The involvement of antagonist muscle co-activation remains unclear. The aim of this study was to investigate the difference in muscle co-activation between elderly and young healthy subjects during a point-to-point RT-test. We hypothesized that increased antagonist co-activation during the movement phase of the RT-test would be related to longer ...
