Contribution of lower limb eccentric work and different step responses to balance recovery among older adults

Highlights • Balance was better maintained by single-step responses than multi-step responses. • Greater step length and velocity were characterised in single-step responses. • Single-step responses accompanied greater dorsiflexion and knee maximum flexion. • Single-step responses showed greater neg...

Description
Summary:	Highlights • Balance was better maintained by single-step responses than multi-step responses. • Greater step length and velocity were characterised in single-step responses. • Single-step responses accompanied greater dorsiflexion and knee maximum flexion. • Single-step responses showed greater negative work at the ankle and knee. • Falling momentum can be absorbed as lower limb eccentric work for balance recovery.
