Consensus on a netball video analysis framework of descriptors and definitions by the netball video analysis consensus group.

Using an expert consensus-based approach, a netball video analysis consensus (NVAC) group of researchers and practitioners was formed to develop a video analysis framework of descriptors and definitions of physical, technical and contextual aspects for netball research. The framework aims to improve the consistency of language used within netball investigations. It also aims to guide injury mechanism reporting and identification of injury risk factors. The development of the framework involved a systematic review of the literature and a Delphi process. In conjunction with commercially used descriptors and definitions, 19 studies were used to create the initial framework of key descriptors and definitions in netball. In a two round Delphi method consensus, each expert rated their level of agreement with each of the descriptors and associated definition on a 5-point Likert scale (1-strongly disagree; 2-somewhat disagree; 3-neither agree nor disagree; 4-somewhat agree; 5-strongly agree). The median (IQR) rating of agreement was 5.0 (0.0), 5.0 (0.0) and 5.0 (0.0) for physical, technical and contextual aspects, respectively. The NVAC group recommends usage of the framework when conducting video analysis research in netball. The use of descriptors and definitions will be determined by the nature of the work and can be combined to incorporate further movements and actions used in netball. The framework can be linked with additional data, such as injury surveillance and microtechnology data.

The Applied Sports Science and Medicine of Netball: A Systematic Scoping Review.

BACKGROUND: Netball is the one of the most popular women's sports in the world. Since gaining professional status in 2008 there has been a rapid growth in research in the applied sports science and medicine of the sport. A scoping review of the area would provide practitioners and researchers with an overview of the current scientific literature to support on-court performance, player welfare and reduce injury. OBJECTIVE: The primary objective was to identify the current research on the applied sports science and medicine of netball. Additionally, the article provides a brief summary of the research in each topic of sports science and medicine in netball and identifies gaps in the current research. METHODS: Systematic searches of PubMed, SPORTDiscus, MEDLINE and CINAHL were undertaken from earliest record to Dec 2020 and reference lists were manually searched. The PRISMA-ScR protocol was followed. Studies were eligible for inclusion if they investigated netball as a sport or the applied sport science and medicine of netball athletes. RESULTS: 962 studies were identified in the initial search, 150 of which met the inclusion criteria. Injury was the most highly investigated sport science and medicine topic (n = 45), followed by physical qualities (n = 37), match characteristics (n = 24), biomechanics (n = 15), psychology (n = 13), fatigue and recovery (n = 9), training load (n = 4) and nutrition (n = 3). A range of cohorts were used from school to elite and international standards. All cohorts were female netballers, except for one study. A rapid growth in studies over recent years was demonstrated with 65% of studies published in the last decade. There still remains gaps in the literature, with a low evidence base for nutrition, training load and fatigue and recovery. CONCLUSION: This scoping review summarises the current evidence base and key findings that can be used in practice to enhance the applied sport science and medical support to netball athletes across a range of playing standards, and support the growth of the sport. It is evident that netball as a sport is still under-researched.

Accelerated rehabilitation after arthroscopic Bankart repair in professional footballers.

BACKGROUND: Advances in arthroscopic surgery have resulted in biomechanically stronger repairs that might allow for accelerated rehabilitation protocols and hence faster return to play. Evidence for such regimes in the shoulder, particularly in elite athletes, is lacking. METHODS: This prospective single surgeon (PB) series included 34 professional footballers undergoing an accelerated rehabilitation programme following arthroscopic soft tissue stabilization subsequent to traumatic anterior shoulder dislocation. Data were collected on time to regain elevation range, external rotation range, return to play and rate of recurrence. RESULTS: Mean follow-up time was 4.8 years (range 2 years to 10 years). Full range of forward elevation was regained at a mean of 5 weeks (range 3 weeks to 7 weeks) and external rotation range (in neutral) at a mean of 6 weeks (range 4 weeks to 8 weeks). Mean return to play time was 11 weeks (range 9 weeks to 14 weeks). Three players (9%) reported a recurrent episode of dislocation at a mean of 19 months. CONCLUSIONS: An accelerated rehabilitation programme resulted in a return to play time of 11 weeks compared to previously reported times of between 5 months and 9 months in the contact sports population. A recurrence rate of 9% compares favourably to other published studies following similar surgery (5.1% to 28.6%) but which employed more conservative postoperative rehabilitation regimes.
