Humans need only 200 ms to generate posture-specific muscle activation patterns for successful vertical jumps in reaction to an auditory trigger by Bobbert, Maarten F, Koopman, Axel S

“…It is currently unknown how the central nervous system controls ballistic whole-body movements like vertical jumps. Here we set out to study the time frame of…”

Contribution of the support limb in control of angular momentum after tripping by Pijnappels, Mirjam, Bobbert, Maarten F., van Dieën, Jaap H.

“…Tripping over an obstacle can result in a fall when the forward angular momentum, obtained from impact with the obstacle, is not arrested. Angular momentum can…”

How early reactions in the support limb contribute to balance recovery after tripping by Pijnappels, Mirjam, Bobbert, Maarten F., van Dieën, Jaap H.

“…Tripping causes a forward angular momentum that has to be arrested to prevent a fall. The support limb, contralateral to the obstructed swing limb, can…”

Why is the force-velocity relationship in leg press tasks quasi-linear rather than hyperbolic? by Bobbert, Maarten F

“…Force-velocity relationships reported in the literature for functional tasks involving a combination of joint rotations tend to be quasi-linear. The purpose of…”

Push-off reactions in recovery after tripping discriminate young subjects, older non-fallers and older fallers by Pijnappels, Mirjam, Bobbert, Maarten F., Dieën, Jaap H. van

“…Tripping is a major cause for falls, especially in the elderly. This study investigated whether falls in the elderly can be attributed to inadequate push-off…”

Control of support limb muscles in recovery after tripping in young and older subjects by PIJNAPPELS, Mirjam, BOBBERT, Maarten F, VAN DIEËN, Jaap H

“…Older people fall more often after tripping than young people due to a slower development of mechanical responses. This might be due to age-related changes in…”
