In trials with successful forward fall recovery using a single step, younger adults and older adult nonfallers generated sufficient backward angular impulse to neutralize the forward angular momentum of the body induced by the trip.
Collectively, these results suggest that improvements in muscle strength and rate of muscle force development may give older adult fallers the muscular capacity to regulate angular impulse during the push-off phase.
To counteract the backward angular momentum induced by the perturbation, the body must generate forward angular impulse during interaction with the environment.
As in forward fall recovery, longer step lengths are associated with greater braking forces and angular impulse applied during contact to oppose the linear and angular momentum induced by the perturbation.
The NJM patterns observed during swing leg contact phase (ankle plantar flexor, knee extensor, and hip flexor) were similar to those tasks requiring forward angular impulse generation [22,25-26,40].
During the forward fall recovery, a set of ankle plantar flexor, knee flexor, and hip extensor NJMs was used for neutralizing the forward angular impulse during the impact phase [5].
