Torque–Velocity is Associated With Voluntary Activation and Corticospinal Excitability in Healthy Knees, but Not Following Anterior Cruciate Ligament Reconstruction
Puntos clave
This research aims to explore how torque-velocity relationships relate to voluntary activation and corticospinal excitability in knees, both healthy and post-ACL reconstruction.
Analyzed torque-velocity relationships during isometric contractions
Compared voluntary activation and corticospinal excitability in healthy limbs versus ACLR limbs
Significant associations found in healthy knees between torque-velocity and voluntary activation
No significant associations in limbs after ACL reconstruction for torque-velocity and activation
Corticospinal excitability showed similar patterns, indicating a difference in knee condition effects.
Resumen
Two-point torque-velocity relationships incorporating isometric contractions were associated with both voluntary activation and corticospinal excitability in healthy participants but not in ACLR limbs.
