Antagonist coactivation is the simultaneous activation of agonist and antagonist muscles
during a motor task. Age-related changes in coactivation may contribute to observed …

The aim of this study was to determine the muscle co-activations and joint stiffnesses around
the hip, knee, and ankle during different walking speeds and to define the relationships …

Objectives Despite the growing use of whole-body vibration (WBV) to enhance quadriceps
