Dynamic legged robots are capable of a wide range of behaviors, such as running, climbing and jumping. In each of these cases the leg morphology, compliance, and postural control all interact to enable dexterous, dynamic motion. In this paper we examine the design trade-offs between these factors in producing stable running and powerful jumping. Specifically we examine the stability of a SLIP-l...

The purpose of this study was to clarify the kinetic characteristics take-off leg during phase required effectively change direction center mass velocity vector in running single-leg jump (RSLJ) by comparing kinetics jumpers and sprinters. Nine male collegiate 9 sprinters performed RSLJ 2 tasks designed achieve as much forward upward motion possible, respectively, with 4 different run-up speeds...

An ankle-foot orthosis (AFO) is often prescribed to patients with instability or weakness in the lower leg to assist plantarflexion or dorsiflexion [1]. A limited number of studies focuses on the optimal stiffness of the AFO. It is known that excessive AFO stiffness introduces buckling in the knee [1]. It would be desirable to have the ability to predict the effect of an AFO on the gait of a sp...

Differences in the adaptation processes between muscle and tendon response to mechanical loading can lead non-uniform properties within muscle–tendon unit (MTU), potentially increasing injury risk. The current study analysed of triceps surae (TS) MTU 10 young (YS; 22 ± 3 yrs) older (OS; age 65 8 yrs; i.e. master) (inter)national level sprinters 11 recreationally active adults (YC; 23 detect pos...
