Objective: Current return-to-sport decisions are primarily based on elapsed time since surgery or injury and strength measures. Given data that show rates of successful return to competitive sport at around 55%, there is strong rationale for adopting tools that will better inform return to sport decisions. The authors' objective was to assess reac...

There exists a great variety of posturographic para-meters which complicates the evaluation of center of pressure (COP) data. Hence, recommendations were given to use a set of complementary parameters to ex-plain most of the variance. However, it is unknown whether a dual task paradigm leads to different para-metrization sets. On account of this pr...

Interleukin-4 (IL-4) and interleukin-13 (IL-13) are Th2 cytokines involved in various immune responses and only a few reports examine skeletal muscle and the possible role of Th2 cytokines in myoblast fusion and myotube maturation. We hypothesized that IL-4, IL-13 and their receptors are involved in skeletal muscle adaptations to strength training....

Zusammenfassung Das Muskelaufbautraining zielt vorrangig auf die Steigerung der Muskelmasse ab. Eine Prä-misse hierzu lautet, dass die Ausbelastung der Muskulatur als adaptiver Reiz (neben der mög-lichen energetischen Ausschöpfung) anzusehen ist. Augustsson et al. sowie Maynard und Eb-ben konnten u.a. zeigen, dass die Vorermüdung als Intensitätstec...

We explored the effects of random whole-body vibration on leg proprioception in Parkinson's disease (PD). In earlier studies it was found that this treatment leads to improved postural control in these patients. Thus, one could speculate that these effects result from modified proprioceptive capabilities. Twenty-eight PD patients were subdivided in...
