Hierf{\"u}r vollzogen zehn gesunde m{\"a}nnliche Probanden zu drei Testzeitpunkten isometrische Erm{\"u}dungsmessungen. Hintergrund Bei der Messung des ueEMG werden die Motor Units Aktionspotentiale (MUAPS) elektrisch {\"u}berlagert. Physiologische Muskelerm{\"u}dung zeigt sich hier unter anderem in der Ver{\"a}nderung des Frequenzspektrums und der Signalamplitude. Letzteres steigt bei Erm{\"u}dung an, wohingegen die mediane Frequenz (MF) sinkt. Eine weitere M{\"o}glichkeit die Muskelerm{\"u}dung mittels Oberfl{\"a}chen-EMG zu ermitteln ist die Anwendung des dEMGs. Dieses erm{\"o}glicht mithilfe einer Mustererkennungssoftware einzelne MUAPS zu erkennen. Studien zeigten, dass aktive Motor Units (MU) bei wiederholten oder anhaltenden submaximalen Kontraktionen als Muskelerm{\"u}dung ihre Feuerungsrate erh{\"o}hen und neue MU rekrutiert werden. Bisher wurden diese Methoden jeweils einzeln betrachtet. Um sicherzustellen welcher Ansatz f{\"u}r klinische Daten geeigneter ist, wurden Datens{\"a}tze zu beiden Methoden gleichzeitig generiert und hinsichtlich ihrer Aussagekraft und Wiederholbarkeit mit statistischen Mitteln verglichen.}, subject = {Elektromyogramm}, language = {de} }
