It has been suggested that during repeated long-term stretch-shortening cycle (SSC)
exercise the decreased neuromuscular function may result partly from alterations in stiffness
regulation. Therefore, interaction between the short latency stretch-reflex component (M 1) …

The purpose of the present study was to examine the acute and long-term fatigue effects of
exhausting stretch-shortening cycle (SSC) exercise on the stiffness of ankle and knee joints.
Five subjects were fatigued on a sledge apparatus by 100 maximal rebound jumps followed …

This study investigated fatigue-induced changes in neuromuscular and stride characteristics
during and immediately after the 5-km running time trial. Eighteen well-trained male distance
runners performed a maximal 20-m sprint test and maximal voluntary contraction (MVC) in a …

In the lower leg, landing after a jump induces reflexes, the role of which is not well
understood. This is even more so for reflexes following landing on inverting surfaces. The
latter condition is of special interest since ankle inversion traumata are one of the most …

In several explosive types of sport events the leg extensor muscles are subjected to very
high impact loads. Thus, extreme requirements exist for the neuromuscular system to
develop sufficient muscle stiffness in the lower extremities in order to tolerate these high …

Abstract Stretch–shortening cycle (SSC)-type fatigue is associated with acute and delayed
functional defects, and appears to be a useful model to reveal the flexibility of both central
and reflex adjustments to the contractile failure. SSC fatigue was induced in an experimental …

The present study examined the muscle–tendon interaction of ten international level Kenyan
runners. Ultrasonography and kinematics were applied together with EMG recordings of
lower limb muscles during repetitive hopping performed at maximal level. The ten Kenyans …

Purpose The purpose of this study was to investigate the effects of surface instability on
measures of performance and activity of leg and trunk muscles during drop jumps and
landings. Methods Drop jumps and landings were assessed on a force plate under stable …

The purposes of this study were to investigate firstly, the ankle joint stiffness during the
eccentric phase in rebound jumps, and secondly, the effect of ankle joint stiffness during the
eccentric phase on ankle joint torque at midpoint. Nine active males executed rebound drop …
