ISBS 2020 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.
A total of 242 papers were accepted into this year’s proceedings. These papers were not formally presented although members were invited to upload their presentation to the ISBS YouTube channel. There were at least two independent reviewers for each paper. The organising committee thanks all member of the scientific committee and the ISBS members who gave their time to undertake these reviews
PEAK MAGNITUDES OF DYNAMIC KNEE JOINT LOADING ARE NOT INFLUENCED BY CUSTOMISED BODY SEGMENT PARAMETERS
Although accurate body segment parameters (BSPs) do not appear to be important for peak joint moments recorded during walking, it is not clear whether joint moment magnitudes during highly dynamic activities can be modified when using individualised BSP data and having high frequency motion characteristics retained in the segmental acceleration data. Overall, it was found that BSPs had little influence on peak knee joint moment magnitudes during 45°cutting, drop jumping and fast running (even with high frequency signal components (up to 30 Hz) present in the dataset). This supports previous walking gait research that suggests BSPs have only a small effect on knee joint moment calculations

Papers underwent a double blinded review process. Each paper in these proceedings has been reviewed by at least two members of the scientific committee
Clearing Up Rollo May’s Views of Transpersonal Psychology and Acknowledging May as an Early Supporter of Ecopsychology
This paper explores Rollo May’s 1992 reassessment of transpersonal psychology, in which he reverses
his 1986 and 1989 arguments against transpersonal psychology. Equally relevant, this paper shows
that May was actually interested in supporting what is now called ecopsychology. Schroll (following
Alan Drengson and Arne Naess) now refers to ecopsychology as transpersonal ecosophy. This paper
offers a thorough examination of several key concerns that May had regarding his reservations
toward accepting transpersonal psychology’s legitimacy, and includes May’s vigorous discussion with
Ken Wilber. Wilber’s discussion with Kirk Schneider’s 1987 and 1989 critique of transpersonal
psychology is also examined. Likewise Albert Ellis’ 1986 and 1989 rejection and misunderstanding
of transpersonal psychology is discussed
REDUCED MOVEMENT ADAPTABILITY IN SIDESTEPPING – A POSSIBLE SOURCE OF INJURY RISK
Adapting to different task constraints provides insight into how malleable an athlete’s movement dynamics are. The purpose of this pilot study was to investigate whether athletes can adequately change their preferred movement strategy during sidestepping when exposed to a manipulation task. Reduced movement adaptability was hypothesized to be one risk factor for ACL injuries. Fourteen male team sport athletes were investigated. The response to the manipulation task was intra-individual, with rearfoot strikers being less able to adapt their movement strategy and the resulting movement was even higher associated with ACL risk factors. Forefoot strikers were able to adapt their movement. This suggests, that athletes need to be investigated individually as group-based analyses might cover effects and that movement adaptability should be considered when evaluating injury risk
COMPARISON OF PLUG-IN GAIT AND A SIX DEGREES OF FREEDOM MODEL ON ESTIMATING KNEE KINEMATICS DURING A DOUBLE LEG DROP JUMP
Biomechanical models allow for a comprehensive understanding of dynamic movements that could be used to assess athletic performance or identify injury risk and return to play status. In order to make clinical recommendations based on these model outputs, discrepancies between modelling approaches need to be identified. The purpose of this study was to compare the knee kinematics between the commonly used Plug-in Gait model and a six degrees of freedom model during the first landing a double leg drop jump (DLDJ). This study identified differences in the model outputs for knee kinematics, most prominently in the frontal and transverse planes. Further investigation is required to determine the reliability and sensitivity of these model outputs
