Improved postural control after slackline training is accompanied by reduced H-reflexes

Keller, M. ; Pfusterschmied, J. ; Buchecker, M. ; Müller, E. ; Taube, Wolfgang

In: Scandinavian Journal of Medicine & Science in Sport, 2012, vol. 22, no. 4, p. 471–477

“Slacklining” represents a modern sports activity where people have to keep balance on a tightened ribbon. The first trials on the slackline result in uncontrollable lateral swing of the supporting leg. Training decreases those oscillations and therefore improves postural control. However, the underlying neural mechanisms are not known. Therefore, the present study aimed to highlight...

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...

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

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...
