3DRSBA stands for 3D Remote Sports Biomechanics Analysis. The aim of the 3D Remote Biomechanic Sport Analysis is establish remote biomechanical service for health screening of young athletes. By combining existing high end 3D capture systems with modern tools in communication, such as high speed internet, cloud storage and the new 4G mobile network, biomechanical sport studies can be moved outside to the training side, without losing the scientific and medical support a motion laboratory can provide. It combines the power of 3D motion capture in biomechanical laboratories (CAR) with the necessities in sports analysis to provide reality-close surroundings in measuring (training sites at CAR).
The structured analysis of motion has become a very important tool in sports analysis. Using new video technology, tactics and performance studies in team sports increases the performance and general success. Besides the general motion studies, biomechanics intends to measure the motion and relates it to the underlying musculoskeletal function. This provides information for the performance of a single athlete, but can also provide information about the health status of the individual regarding the musculoskeletal system. A very wide range of technologies for motion capture are available, hence the outcome differs significantly with each system. Additionally, the technique and analysis differs widely, depending on the methodology used. For example, animation needs a continuously and steady signal, but does not need a physiological precision of the individual. The latter would be essential for clinical science, where motion capture needs to be complemented with other systems, such as force measurements and electromyography. This is needed in order to not just measure motion, but to analyse and comprehend the reason for the motion. This complexity is not just related to the technology applied, but also to the methodology behind the analytics. This is known as the biomechanical model.
Whilst general motion analysis is used in the field, clinical motion analysis is more restricted to specialised laboratories, which consist of complex technology and specialised professionals to handle it. Currently, the professional education of such professionals is extensive and requires many years of experience; hence the availability of such experts is limited. This results in one of the main obstacles: the limited availability of biomechanically literate technical staff in addition to trainers; more so during busy periods of multiple training sessions in different locations at CAR. Whilst the laboratory approach delivers results of high technical quality, with carefully controlled parameters, it comes with some disadvantages. A full analysis session in the laboratory is an interruptive event in the already tight schedule of an elite athlete with a professional training plan and living and other educational requirements.
The proposed experiment will focus on bringing biomechanical screening techniques directly to the training site of the athlete at CAR. The high number of athletes at CAR does not allow monitoring and testing all of them and general biomedical services are limited. Notwithstanding these concerns, the screening of musculo-skeletal performance has been widely suggested in sports science and yet, other than in a few exceptional cases, there is no widespread provision. By bringing together these powerful technologies – the motion tracker by Qualisys, control remote technologies as well as the communication interface established at CAR – under the auspices of the EXPERIMEDIA project, one can expect a direct payoff in the Quality of Service (QoS) provided by the institution, as well as Quality of Experience (QoE) for the athlete.
Qualisys combined the power of their 3D motion capturing system with the experience from Bertram Müller [www.motion-and-more.eu], as a clinical scientist. With close collaboration with the biomechanical laboratory at CAR, a very strong team has been established to provide biomechanical health service to a wider population. Focus will be given to the remote application of such technology and to specialised biomechanical models. The first medical aim will focus on the risk-detection and prevention of non-contact knee lesions.
