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...
In this investigation, the stretch-shortening cycle (SSC) performance of untrained male children and juveniles was measured and compared to that of soccer-playing children of equivalent age.

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...
