Modelling Biomechanics Applied Session@ ISBS 2011

Aim

The aim of the Modelling Biomechanics Applied Session is to discuss de use of modelling in the context of Sport Biomechanics. The participant will cover different type of modelling approaches ranging from the more simple forward and inverse dynamics applications to more complex musculoskeletal simulation, and from how to use modelling instruments to reduce errors in experimental laboratory movement capture to the use of induced acceleration to study sports performance. The discussion of the limitations of biomechanics modelling and the careful use that should be done of their results, but also of the promising and unique possibilities that models could provided answer to questions that could only be studied using biomechanical simulation.

The theoretical foundations

The use of biomechanical modelling approach more common in sports biomechanics than usually notice, for example, on the applied session the first talk will address the application of modelling approach to the reduction of tracking errors associated to motion capture, and how to use new optimization techniques could contribute to reduce those errors. Mass spring models can be used to study some main mechanical properties of the human body, like body natural frequency stiffness and damping properties during jumping and running and the some of the possible consequences will be studied in the session. Induced acceleration analysis being used to explain some clinical aspects of gait but was seldom applied to sports biomechanics optimization. The optimization of throwing in baseball pitching and also jumping performance in figure skating will be studied using individual moment joint moment of force contribution to power development in both sports using induced acceleration approach. The use of forward dynamics simulation has a strong potential for the optimization of sports techniques and sports performance, but some limitations should be addressed.

Finally, an uncompromising discussion on the implications that  theoretical and experimental studies on muscle properties that underlie biomechanics research has, not only when biomechanics modelling is used, but also for the interpretation of experimental data in applied or laboratorial studies.

Presenters Biographies

Scott Selbie
Queen’s University (Canada), and the University of Massachusetts (USA).
Has been the President and Director of Research at HAS-Motion (an R&D affiliate of C-Motion) since 2008. He is currently an adjunct Professor at Queen’s University (Canada), and the University of Massachusetts (USA).  He got his PhD in Biomechanics from Simon Fraser University (1990), he received post doctoral training at the University of Geneva, the University of Leuven, and Queen’s University. He was a staff scientist at the U.S. National Institutes of Health where he focused on biomechanical modeling of the human larynx, and three dimensional reconstructions of biological structures from various medical imaging modalities, and was an inventor on 3 US Patents.  He is the former Director of Biomedical Visualization for Medical Consumer Media (MCM) where he developed an immersive virtual environment for Oncologists. Scott was Director of Research at C-Motion from 1998-2008, and has directed the evolution of C-Motion’s Visual3D software since the original technology transfer from the National Institutes of Health. Scott has been the Principal Investigator on all but one of C-Motion’s NIH grants and contracts.

Wangdo Kim
Biomechanics Laboratory, Faculty of Human Kinetics, Technical University of Lisbon, Portugal.
His original training was in mechanical engineering; he has a BSc from Seoul National University and a PhD from Lehigh University, Bethlehem, PA, USA. His research interests focus on: multi-scale simulation techniques from organ to cells; imaging of tissue deformations; mechanobiological adaptation; virtual physiology of the healthy and pathological musculoskeletal system; or computational modeling and evaluation through movement measurements. Currently, He is conducting multiscale cell to tissue biomechanical and regeneration research to create a computational model replicating gross pericellular biomaterials stress-strains based on cell-level biomechanical boundary conditions. Outcomes for this research will establish a computational way of thinking for understanding the complexity of multiscale biomechanical environments.

Tom Kepple
Currently the Chief Science Officer at C-Motion. Inc. Tom began developing innovative biomechanics software solutions over 25 years ago as at the Biomechanics Lab within the United States’ National Institutes of Health (NIH). During his time at NIH Tom wrote the Move3d software which was awarded as a Regional Winner in the 1992 Johns Hopkins University National Search for Computing to Assist Persons with Disabilities. In 1997 Move3d software was transferred to C-Motion Inc. as part of an NIH Technology Transfer grant. Today Visual3d has grown to be the industry leader in application software for human movement research.  After leaving NIH Tom spend two and half years as Researcher/Instructor at the University of Delaware where in addition to teaching graduate courses in Biomechanics, he developed computer simulation software for United States Figure Skating Association. In August 2010 Tom returned to his roots to work at C-Motion. Inc. and is currently involved in developing new analytical techniques for incorporation into Visual3d and future C-Motion software.

Dr. M.F. (Maarten) Bobbert
Faculty of Human Movement Sciences of the VU University Amsterdam, The Netherlands.

Maarten F. Bobbert obtained in 1983 a M.Sc. degree in Functional Anatomy as well as a M.Sc. degree in Exercise Physiology from the Faculty of Human Movement Sciences of the VU University Amsterdam, The Netherlands. At this faculty, he also conducted his Ph.D. work on muscle functioning and coordination in vertical jumping, which was finalized in 1988. After a two-year post-doc appointment at the Human Performance Laboratory of the University of Calgary, Canada, Maarten returned to Amsterdam to be appointed as staff member. His current teaching includes courses on neurosciences and neuro-musculo-skeletal modelling. Among his research interests are the design of the musculo-skeletal system and the organization of control in the central nervous system. He is editorial consultant of the Journal of Biomechanics, and editorial board member of Human Movement Science, Clinical Biomechanics, and the European Journal of Applied Physiology.
