Pfusterschmied, Jürgen ; Buchecker, Michael ; Keller, Martin ; Wagner, Herbert ; Taube, Wolfgang ; Müller, Erich

In: European Journal of Sport Science, 2013, vol. 13, no. 1, p. 49-57

The present study investigated whether or not four weeks of supervised slackline training (SLT) performed on nylon webbing improves postural stability. Twenty-four healthy adults participated in the study and were assigned to either SLT (n=12) or a control (CON) group (n=12). The SLT group completed a four week training program, while the CON group received no training. Centre of gravity...

Specific interpretation of augmented feedback changes motor performance and cortical processing

Lauber, Benedikt ; Keller, Martin ; Leukel, Christian ; Gollhofer, Albert ; Taube, Wolfgang

In: Experimental Brain Research, 2013, p. -

It is well established that the presence of external feedback, also termed augmented feedback, can be used to improve performance of a motor task. The present study aimed to elucidate whether differential interpretation of the external feedback signal influences the time to task failure of a sustained submaximal contraction and modulates motor cortical activity. In Experiment 1, subjects had to...

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...
