Muskulre Ermdung und Bewegungsverhalten beim Heben von Lasten: Spektralanalytische Untersuchung von dynamischen Muskelkontraktio,Used
Delivery time: 8-12 business days (International)
Das Heben von Lasten ist im Rahmen der Prvention von Rcken beschwerden ein zentraler Punkt der funktionellen Analyse. Bei wiederholendem Heben spielt der Effekt der lokalen muskulren Ermdung eine wichtige Rolle. Dies kann mit Hilfe der Methode der zeitaufgelsten Frequenzanalyse von elektromyografischen Signalen untersucht werden. Die Verfahren zur Analyse dynamischen Muskelkontraktionen mssen dem nichtstationren Charakter der elektrischen Muskelsignale Rechnung tragen. In dieser Arbeit wird ein Algorithmus vorgestellt, der aus der biquadratischen Transformation der CohenKlasse abgeleitet ist. Er zeichnet sich durch eine hohe Zeit und Frequenzauflsung aus. Damit wird es mglich, lokale muskulre Ermdung von bewegungsrelevanten Muskelgruppen whrend dynamischer Kontraktionen zu untersuchen. Das durchgefhrte Testprotokoll (PILE) fhrt zu einer signifikanten Ermdung der Muskeln der Rumpfextensoren whrend dies fr die Muskeln der Beinstrecker bis zum Testabbruch nicht beobachtet wird. Vergleiche mit nderungen im Bewegungsverhalten zeigen einen Zusammenhang mit den Befunden zum Ermdungsverlauf der Rumpfextensoren.
