Lower between-limb asymmetry during running on treadmill compared to overground in subjects with laterally pronounced knee osteoarthritis

Subjects with knee osteoarthritis (KOA) show gait asymmetries evidenced by lower knee flexion and shorter contact times for the affected leg. Interestingly, running on a treadmill compared to running overground is also associated with lower knee flexion and shorter contact times. Thus, it is of particular interest how gait patterns are influenced by the type of ground in subjects with KOA....

The effect of whole body vibration on the H-reflex, the stretch reflex, and the short-latency response during hopping

Ritzmann, R. ; Kramer, A. ; Gollhofer, Albert ; Taube, Wolfgang

In: Scandinavian Journal of Medicine & Science in Sports, 2011, p. -

The effect of whole body vibration (WBV) on reflex responses is controversially discussed in the literature. In this study, three different modalities of reflex activation with increased motor complexity have been selected to clarify the effects of acute WBV on reflex activation: (1) the electrically evoked H-reflex, (2) the mechanically elicited stretch reflex, and (3) the short-latency...

The drop height determines neuromuscular adaptations and changes in jump performance in stretch-shortening cycle training

Taube, Wolfgang ; Leukel, Christian ; Lauber, B. ; Gollhofer, Albert

In: Scandinavian Journal of Medicine & Science in Sports, 2011, p. -

There is an ongoing discussion about how to improve jump performance most efficiently with plyometric training. It has been proposed that drop height influences the outcome, although longitudinal studies are missing. Based on cross-sectional drop jump studies showing height-dependent Hoffmann (H)-reflex activities, we hypothesized that the drop height should influence the neuromuscular...

Spinal reflex plasticity in response to alpine skiing in the elderly

Lauber, B. ; Keller, Martin ; Gollhofer, Albert ; Müller, E. ; Taube, Wolfgang

In: Scandinavian Journal of Medicine & Science in Sports, 2011, vol. 21, no. s1, p. 62–68

The present study was designed to assess the influence of 12 weeks (28.5±2.6 skiing days) of alpine skiing on spinal reflex plasticity, strength and postural control in senior citizens. Therefore, soleus H-reflexes and postural stability were measured during bipedal quiet and unstable stance in 22 (12 male and 10 female) elderly subjects aged 66.6±1 years. Furthermore, the maximal isometric...

Changes in predictive motor control in drop-jumps based on uncertainties in task execution

Leukel, Christian ; Taube, Wolfgang ; Lorch, Michael ; Gollhofer, Albert

In: Human Movement Science, 2011, p. -

Drop-jumps are controlled by predictive and reactive motor strategies which differ with respect to the utilization of sensory feedback. With reaction, sensory feedback is integrated while performing the task. With prediction, sensory information may be used prior to movement onset. Certainty about upcoming events is important for prediction. The present study aimed at investigating how...
