VISUAL ASSESSMENT TOOLS IN TENNIS

The ability to analyse high-speed strokes in tennis is at least in-part dependant on a coach’s ability to ‘see’ the critical features of the stroke being analysed. While the ‘eye’ provides visual feedback of the highest order, there are times when technology can play an important role in assisting a coach to observe specific body movements or alternatively to present ‘pictures of performance’ to a player. Visual feedback is an integral part of performance feedback. This paper will discuss the different visual approaches that may be used by coaches. A relatively recent development the high-speed opto-reflective motion analysis system, has offered an alternate research design investigating tennis stroke production. Using such a system, results from a service analysis of high performance players will be presented in an endeavour to better understand the inter-relationship between the legs and the trunk in the tennis serve

THE PERSONALISED 'DIGITAL ATHLETE': An evolving vision for the capture, modelling and simulation, of on-field athletic performance

Technological advances in the areas of three-dimensional (3D) body scanning, in-vivo imaging and novel forms of motion capture and data analytics (e.g. deep learning neural networks) are rapidly bridging the lab versus field-based nexus that has historically plagued the applied sport biomechanist. Similarly, exponential advances in hardware and computer processing power has witnessed the emergence of the personalised 'digital athlete', an overarching vision that facilitates, via the integration of multiple technologies, real-time biomechanical data collection, modelling and reporting for immediate biofeedback

ARTIFICIAL INTELLIGENCE, DATA ANALYTICS AND SPORTS BIOMECHANICS: A NEW ERA OR A FALSE DAWN?

The adoption of wearable technologies combined with emerging and evolving data science techniques has the potential to do for sports biomechanists what the industrial revolution did for manufacturing. Yet the full capability of these technologies and methods will likely only be realised if sport scientists are embedded in their application and driving the questions being asked

Sports Injury Prevention: Are we tilting at windmills?

Injury prevention frameworks (e.g. Translate Research into Injury Prevention Practice) are critical for reducing injury rates. However, their success relies heavily on the available information within each stage of the framework. Using anterior cruciate ligament injury prevention research as a working example; this paper presents a rationale for the cultivation of cross-disciplinary injury prevention research groups and highlights the role of biomechanics in informing each stage of the injury prevention framework

TRANSVERSE AND FRONTAL PLANE LOWER LIMB 'KINEMATICS IN FEMALE RUNNERS WITH PATELLOFEMORAL PAIN

Patellofemoral pain syndrome (PFPS), one of the most common disorders in running has been shown to affect females more frequently than males. The aetiology of patellofemoral pain syndrome is not clear but abnormat hip and ,knee frontal and transverse plane motion are commonly associated with the disorder. This study investigated transverse and frontal plane kinematics and kinetics in female runners symptomatic and asymptomatic for patellofemoral pain. The findings of this study did not reflect the common clinically held association between excessive femoral intemal rotation, internal tibial rotation and knee valgus in runners with PFPS. The PFPS subjects displayed greater external hip and external knee rotation compared with asymptomatic runners. The results have identified a different set of mechanical conditions which may affect patella tracking

ISBS 2018 AUCKLAND CONFERENCE PROCEEDINGS TITLE AND FOREWARD

The ISBS is an international society totally dedicated to biomechanics in sports, whose primary purposes are: To provide a forum for the exchange of ideas for sports biomechanics researchers, coaches and teachers. To bridge the gap between researchers and practitioners. To gather and disseminate information and materials on biomechanics in sports. ISBS 2018, held at the AUT City Campus in Auckland, New Zealand, was hosted in partnership between AUT, AUT Millennium, High Performance Sport New Zealand (HPSNZ) and Auckland Tourism Events and Economic Development (ATEED). Conference organisers are proud to have organised an eco-friendly sustainable conference. All documents (programme, presentation schedule, papers, proceedings etc.) are electronic only. Published in the following proceedings are 275 papers across keynote, oral podium and oral poster pitch and digital poster presentations. There were at least two independent reviewers for each paper. The organising committee is indebted to all member of the scientific committee and the ISBS members who were willing to spend their time, energy and experience to undertake these reviews

SYNTHESISING 2D VIDEOS FROM 3D DATA: ENLARGING SPARSE 2D VIDEO DATASETS FOR MACHINE LEARNING APPLICATIONS

This study outlines a technique to repurpose widely available high resolution three-dimensional (3D) motion capture data for training a machine learning model to estimate the ground reaction forces from two-dimensional (2D) pose estimation keypoints. Keypoints describe anatomically related landmarks in 2D image coordinates. The landmarks can be calculated from 3D motion capture data and projected to different image planes, serving to synthesise a near-infinite number of 2D camera views. This highly efficient method of synthesising 2D camera views can be used to enlarge sparse 2D video databases of sporting movements. We show the feasibility of this approach using a sidestepping dataset and evaluate the optimal camera number and location required to estimate 3D ground reaction forces. The method presented and the additional insights gained from this approach can be used to optimise corporeal data capture by sports practitioners
