Ground reaction force prediction with the AnyBody Modeling System (Assoc. Prof. Michael Skipper Andersen and Sebastian Skals, M.Sc., Aalborg University, 06. October, 2015) Presentation (5MB), Playback (85MB), YouTube This webcast will show how to implement ground reaction force prediction for models in the AnyBody Modeling System. The webcast will have both hands-on examples as well as results from validating the approach against measured ground reaction forces in different sports related activities.

Development of a musculoskeletal simulator for swimming (Dr. Motomu Nakashima, 3. October, 2007) Presentation (0.6mb), Playback (26mb), Get WebEx Player, YouTube There have been no studies of the musculoskeletal analysis for swimming so far because of the difficulty to estimate the fluid force acting on the swimmer's whole body, although such analysis will provide useful information for the athlete swimmer's training and coaching. Therefore, we developed a musculoskeletal simulator for swimming by integrating the AnyBody Modeling System and our simulation model SWUM (SWimming hUman Model), which enables to calculate fluid force acting on the whole body during swimming. In this webcast, how to integrate AnyBody and SWUM, simulation results of animations for crawl, breast, back and butterfly strokes, and a comparison with EMG are presented.

Physiological responses to bicycle design (Ernst Albin Hansen, 25. March, 2010) Presentation (1.1Mb), Playback (21Mb), Get WebEx Player An expert on bicycle biomechanics presents his recent investigation where AnyBody was used to explain remarkable experimental findings that the Biopace chain wheel significantly reduces the blood lactate concentration. Bicycle design is an obvious area for biomechanical simulation and the chain wheel shape is just one of many possible design parameters that can be investigated.

Cross-country skiing biomechanics using measurement driven full-body simulations (Joakim Holmberg, 19. February, 2008) Presentation (2.6mb), Playback (12Mb), Get WebEx Player, YouTube Studies of cross-country skiing biomechanics is traditionally based on measurements alone. Performing musculoskeletal simulations of cross-country skiing enhances the possibilities for studies of technique, equipment and injury prevention. The simulation model is based on the full-body model from the AnyBody model repository and measured boundary conditions (motion and pole forces). Results show consistency with literature and also reveal new information of load distribution between muscles. This application shows that it can be possible to use inverse dynamics and static optimization (i.e. the technology behind AnyBody) on rather fast and complex full-body motion. Furthermore, it shows one way of driving symmetrical movements that takes place mainly in the sagittal plane.
