12. Anpassung an Krafttraining

verfasst von : Henning Wackerhage, Stefan Oesen, Marlene Hofmann, Harald Tschan

Erschienen in: Molekulare Sport- und Leistungsphysiologie

Verlag: Springer Vienna

Zusammenfassung

Ziel des Krafttrainings ist es, Muskelmasse und Kraft zu steigern. Um dies zu erreichen, führen Sportler ein progressives Krafttraining durch, um mit hohen Widerständen die Innervation der trainierten Muskeln, die Muskelmasse und die Kraft per Muskelquerschnitt zu erhöhen. Die Trainierbarkeit der Kraft und die absolute Kraft hängen zudem von dem Talent ab, welches von Variationen der DNA-Sequenz abhängt. Krafttraining aktiviert die mTOR-Kaskade und diese Aktivierung ist für die Erhöhung der Muskelmasse und damit die Hypertrophie notwendig. Der Myostatin-Smad-Signalweg reguliert die Muskelmasse auch, doch die Rolle bei der Anpassung an Krafttraining ist unklar. Zum Schluss dieses Kapitels wird auf die Satellitenzellen eingegangen, die bei der Regeneration und Anpassung nach einem Kraftreiz eine Sonderstellung einnehmen.

Knie-TEP: Kein Vorteil durch antibiotikahaltigen Knochenzement

29.05.2024 Periprothetische Infektionen Nachrichten

Zur Zementierung einer Knie-TEP wird in Deutschland zu über 98% Knochenzement verwendet, der mit einem Antibiotikum beladen ist. Ob er wirklich besser ist als Zement ohne Antibiotikum, kann laut Registerdaten bezweifelt werden.

28.05.2024 Häusliche Gewalt Nachrichten

In der Notaufnahme wird die Chance, Opfer von häuslicher Gewalt zu identifizieren, von Orthopäden und Orthopädinnen offenbar zu wenig genutzt. Darauf deuten die Ergebnisse einer Fragebogenstudie an der Sahlgrenska-Universität in Schweden hin.

Fehlerkultur in der Medizin – Offenheit zählt!

28.05.2024 Fehlerkultur Podcast

Darüber reden und aus Fehlern lernen, sollte das Motto in der Medizin lauten. Und zwar nicht nur im Sinne der Patientensicherheit. Eine negative Fehlerkultur kann auch die Behandelnden ernsthaft krank machen, warnt Prof. Dr. Reinhard Strametz. Ein Plädoyer und ein Leitfaden für den offenen Umgang mit kritischen Ereignissen in Medizin und Pflege.
