Where does the strength of stretched muscles come from? Learn more about our research on in vivo eccentric muscle function in the RUB news.

We are very thankful to the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) for their support of our research on stretch-shortening cycle contractions (SSCs). The aim of this research project is to provide a holistic analysis of contractile, biomechanical, and neuromechanical factors contributing to the increased performance during SSCs. Overall, this research project increases knowledge on basic muscle function and helps to better understand SSCs as one of the most important type of muscle action of everyday human locomotion. This is not only interesting in terms of basic research on muscle function but also has the potential to contribute to the development of efficient humanoid motors as used in medical devices, robotics and prosthetics.

We are very proud and congratulate our team member Dr Brent Raiteri for becoming 1^st place winner of the Young Investigators Award of the European College of Sport Science (ECSS)! This competitive and prestigious award is an integral part of the annual ECSS congresses and was established for the promotion of young scientists and the fostering of scientific excellence. Brent was awarded for his outstanding research on in vivo human muscle mechanics entitled “Muscle-tendon length and force affect human tibialis anterior central aponeurosis stiffness in vivo”. Within this study, which was conducted under the supervision of Dr Andrew Cresswell and Dr Glen Lichtwark at the University of Queensland (Brisbane, Australia), it was shown that the aponeurosis has distinct elastic features compared to the tendon that should no longer be neglected when analyzing in vivo human muscle function.

We are very thankful to the Mercator Research Center Ruhr (www.mercur-research.de/) for supporting our research on the giant muscle protein titin’s role during eccentric contractions. In a one-year pilot project we will setup experiments that involve in vivo biomechanical testing and in vitro muscle testing to investigate human muscle and neurophysiology responses to training.

We are very thankful to the International Society of Biomechanics who awarded our PhD Student Patrick Bakenecker with their Conference Travel Grant. This enables Patrick to attend the upcoming XXVI Congress of the International Society of Biomechanics in Brisbane, Australia and to present his research on eccentric muscle function. http://www.biomech2017.com/

We warmly welcome our new team member Brent J. Raiteri. Brent received a Bachelor with Honors in Exercise and Sport Science from the School of Human Movement and Nutrition Sciences (HMNS) at the University of Queensland, Australia. Afterwards he did his doctoral training in Biomechanics at HMNS and just submitted his thesis entitled “Contraction dependent geometrical changes in human lower limb muscle and aponeurosis”. Brent will join the Department of Human Movement Science as a postdoctoral researcher for the next two years investigating the Neuromechanics of human muscles.
We further welcome our two new student assistants Janna Wohlfarth and Tobias Weingarten.

Heute ist Welttag des Purzelbaums! Und wir haben uns gefragt: Warum ist ausgerechnet der Purzelbaum die erste turnerische Übung, die Kinder lernen? RUB-Sportwissenschaftler Prof. Dr. Daniel Hahn hat eine Theorie.

Wechsel am LFB Bewegungswissenschaft
Zum 01.10.2013 hat Prof. Dr. Daniel Hahn die Leitung des Lehr- und Forschungsbereichs Bewegungswissenschaft von Prof. Dr. August Neumaier übernommen. Dr. Hahn studierte Sportwissenschaft an der TU München und promovierte ebenda zum Dr. rer. nat. im Bereich Biomechanik. Als Postdoc forschte Dr. Hahn am Centre for Sensorimotor Neuroscience der University of Queensland, Brisbane, Australia und habilitierte schließlich zum Thema ‚Neuromechanik muskulärer Aktionen der unteren Extremität‘. Das Forschungsinteresse von Dr. Hahn liegt im Bereich der neuromuskulären Funktion und der neuronalen Kontrolle menschlicher Bewegung.
