Simon Auers work on mental stress in football players has been accepted for publication in “Science and Medicine in Football”. The full title ist: Mental stress reduces performance and changes musculoskeletal loading in football related movements. The paper features experiments on football players which were artificially stressed and analyses changes in kinematics and musculoskeletal loading which was computed using inverse dynamics. Co Autors to the paper are: Simone Kubowitsch, Franz Süß, Tobias Renkawitz (Department of Orthopaedics and Trauma Surgery, Heidelberg University Hospital), Werner Krutsch (Department of Trauma Surgery, Regensburg University Medical Center), Sebastian Dendorfer
Maximilian Melzner will present his work on hand modeling which is part of the EU funded projekt (EFRE Ziel ETZ, BY-CZ) Geburtshilfe 2.0 in an online seminar.
Musculoskeletal research questions regarding the prevention or rehabilitation of the hand can be addressed using inverse dynamics simulations. To date, no complete human hand model implemented in a holistic human body model has been fully developed. Hence, the aim of this work was to develop, implement, and validate a fully detailed hand model using the AnyBody Modeling System.
Sign up for the presentation by Lucas Engelhardt, Researcher at the Scientific Computing Centre Ulm, Germany and Maximilian Melzner, Research Assistant at the Ostbayerische Technische Hochschule Regensburg, Germany.

Erfolgreiche Promotion in der Biomechanik
Mit der erfolgreichen Verteidigung am 12.11.2020 hat Herr Dr. Maxmilian Aurbach seine Promotion im Bereich Biomechanik abgeschlossen. Die Promotion in den Humanwissenschaften (Dr. sc. hum.) wurde von der Universität Regensburg vergeben und von Prof. Dr.-Ing. Sebastian Dendorfer (Labor für Biomechanik, Fakultät Maschinenbau) betreut. Als externe Gutachter konnten für die Arbeit Herr Prof. Dr. Tobias Renkawitz von der Universitätsklinik für Orthopädie und Unfallchirurgie Heidelberg sowie Herr Prof. Dr. John Rasmussen der Universität Aalborg, Dänemark gewonnen werden.
In seiner Arbeit hat Herr Dr. Aurbach virtuelle Menschmodelle entwickelt, welche in den Bereichen Orthopädie und Ergonomie eingesetzt werden. Die Studie war größtenteils in das EU geförderte Projekt „Virtuelle Menschmodelle für die Prävention, Therapie und Rehabilitation von Schulterverletzungen“ (EFRE Bayern 2013-2020, Ziel ETZ CZ-BY) eingebunden. Die Hauptergebnisse der Promotion wurden auch bereit in hochkarätigen Journals publiziert sowie auf mehreren internationalen Kongressen vorgestellt.
Simon Auer will give a webcast about parts of this PhD work. The webcasts will be given in cooperation with AnyBody Technology on the 29th of September. Details can be found here.
Football players have a high risk of leg muscle injuries, especially when exposed to mental stress. Injuries to muscles of the thigh are common in amateur and professional football, representing almost a third of all injuries. These injuries occur primarily in non-contact situations and from overuse. They can lead to a range of costs, including financial costs associated with treatment as well as those associated with long-term recovery, and absence from training and/or competition. Further, there is a high risk of injury recurrence and subsequent injury.
Musculoskeletal models are an established method for analyzing internal body loads in ergonomic or rehabilitation. In the recent past, these models have also been used for more dynamic movements such as those found in soccer. Hence, we investigate the effects of mental stress in highly dynamic motion. This will provide new information on internal loading of the lower extremities and help to prevent injuries.
Another part of Maximilian Aurbachs work on shoulder modeling has been accepted for publication in Journal of Biomechanics. In this paper torus wrapping is introduced in shoulder muscle kinematics and its biomechanical effect is evaluated. More info can be found here.
Obviously also congresses are affected by the current situation. So unfortunately there will be no Congress of the International Society of Biomechanics in Sports this year. However Simon Auers work on footballers under stress has been accepted and the peer reviewed extended abstract is now available in the official proceedings. It can be found here.
Enrico de Pieri from ETH Zürich has successfully published his research on hip contact force pathes in total hip replacement in HIP International. Congratulations for the great work! The work is a collaboration between ETH Zuerich, Schulthess Clinics Zurich and our lab. Some of the computations are based on previous work by Tim Weber.
Last thursday Simon Gross successfully defended his doctoral thesis on the influence of fatigue on musculoskeletal loading. In his work he investigated fatigue of single muscles as well as muscle groups and implemented an novel fatigue algorithm which can be used for musculoskeletal analyses.
Thanks for all the hard work and congratulations!
