Coaches are an integral part of talent identification in sport and often used as the “gold standard” against which scientific methods compared. However, their decision-making during this process is not well understood. In article, we use ecological approach to explore combat sports. We interviewed twenty-four expert, international-level coaches from Olympic disciplines boxing, judo, taekwondo (age: 48.7 + 7.5 years; experience: 20.8 8.3 years). Findings indicated that when identify they rely...

The purpose of this study was to compare upper-body kinematics tennis players when modifying their grip position using a physically constraining tool during the serve. Thirty right-handed performed serves two variations (preferred [Continental], grip-constrained [Precision-continental]) across directions (Deuce, Advantage). Upper limb and racket trajectory data were captured with 60 reflective skin-attached markers 22-camera Vicon motion capture system (240 hz). Shot accuracy similar;...

This study aimed to understand how tennis coaches perceive and approach the development of grip positions, a foundational skill in tennis. Professionally accredited coaches, classed as less (n = 140) or more 86) experienced, participated an online survey where they provided their perspectives on importance developing positions opinions using physically constraining tools for coaching. Irrespective coach experience level, findings revealed that technique position training were ranked two most...

AbstractRecent academic focus has been on reducing the sex data gap for women in sport and exercise research. However, ‘women sport’ is often narrowly represented by female athletes/participants, though there are numerous other positions which also threatened a gap. In this paper, we propose six-pillar framework of to draw attention key areas that can contribute within sporting organisation. paper cover current state play participation across these pillars, identify some challenges...

A typical assumption found in talent identification literature is that different coaches, given the same athletes and circumstances, will identify subset of as “talented”. However, while coaches play a major role during practical sport settings, there limited empirical research exploring processes which underpin this. The purpose this study was to explore reliability “the coach's eye” assessment group athletes. Specifically, project compared inter-coach agreement between nine judo (ages 35.8...

ABSTRACTThe purpose of this study was to compare the upper limb kinematic chain tennis players using either an eastern or continental non-dominant grip position during forward swing double-handed backhand stroke. Sixteen right-handed performed backhands two positions (eastern and continental), aiming for cross-court zones (deep short). Trajectory data were captured sixty reflective markers attached racket a 12-camera Vicon motion capture system (250 Hz). Peak angular velocity significantly...

While the aetiology of rheumatoid arthritis (RA) remains unclear, many inflammatory components are well characterised. For diagnosis and therapy evaluation, in vivo insight into these processes would be valuable. Various imaging probes have shown value including dynamic contrast-enhanced (DCE) MRI PET/CT using 18F-fluorodeoxyglucose (18F-FDG) or tracers targeting translocator protein (TSPO). To evaluate 18F-GE-180, a novel TSPO PET tracer, for detecting quantifying disease activity RA, we...

This study aimed to assess the effectiveness of an online short course in improving knowledge and confidence coaching support staff when working with female athletes. A mixed-methods survey design was used, where participants completed surveys pre-, post-, 6 months following 8-week course. Qualitative responses were analysed inductively using thematic analysis based on two pre-identified themes. Of 92 who both pre- post-course surveys, 72% (n = 66) 67% 62) from team sports. Perceived...

The purpose of this study was to explore the experiential knowledge tennis coaches as it related development grip positions in athletes. Accredited (n = 11) completed semi-structured interviews consisting open-ended questions about their coaching background, importance compared with other areas foundational development, and opinions on using physically-constraining tools (PCTs). Two major themes, “Grip are an adaptive skill” “Why how do I modify athlete’s grip?”, were identified. Coaches...

Motivation: Osteoarthritis (OA) leads to cartilage degradation and pain, impacting patients' lives. MRI allows detailed assessment; however, limited sensitivity hinders early-phase clinical trials developing disease-modifying treatments. Goal(s): To apply 3D surface mapping in a homogeneous patient group over 12 months. Approach: Combined morphological compositional with surface-based analysis assess longitudinal changes within patients mild OA. Results: Bi-directional thickness,...
