This open access book describes the three planning approaches and legacy impacts for the Olympic Games in one locale: the city of Los Angeles, USA. The author critically compares the similarities and ...differences of the LA Olympics by reviewing the 1932 and 1984 Olympics and by analyzing the concurrent planning process for the 2028 Olympics. The author unravels the conditions that make (or do not make) LA28's argument "we have staged the Games before, we can do it again" compelling. Setting the bid's promises into the contemporary local and global mega-event contexts, the author analyzes why LA won the bids, how those wins allowed LA to negotiate concessions with the IOC and NOC, and how legacies were planned, executed, and ultimately evolved. The author concludes with a prediction which 2028 legacy promises might and might not be fulfilled given the local and international Olympic contexts.
Misuse of statistics in medical and sports science research is common and may lead to detrimental consequences to healthcare. Many authors, editors and peer reviewers of medical papers will not have ...expert knowledge of statistics or may be unconvinced about the importance of applying correct statistics in medical research. Although there are guidelines on reporting statistics in medical papers, a checklist on the more general and commonly seen aspects of statistics to assess when peer-reviewing an article is needed. In this article, we propose a CHecklist for statistical Assessment of Medical Papers (CHAMP) comprising 30 items related to the design and conduct, data analysis, reporting and presentation, and interpretation of a research paper. While CHAMP is primarily aimed at editors and peer reviewers during the statistical assessment of a medical paper, we believe it will serve as a useful reference to improve authors' and readers' practice in their use of statistics in medical research. We strongly encourage editors and peer reviewers to consult CHAMP when assessing manuscripts for potential publication. Authors also may apply CHAMP to ensure the validity of their statistical approach and reporting of medical research, and readers may consider using CHAMP to enhance their statistical assessment of a paper.
This study aims to explore how the perceived impacts of sport tourism mediate the relationship between (1) place image and residents' support for sport tourism development and (2) knowledge about ...tourism and residents' support for sport tourism development. A total of 300 local residents participated in this study. The data were analysed using SmartPLS software. The results show that place image and perceived impacts of sport tourism are positively related to residents' support for sport tourism development. Place image and knowledge about tourism are positively related to the perceived impacts of sport tourism. Additionally, the perceived impacts of sport tourism fully mediate the relationship between knowledge about tourism and residents' support for sport tourism development, and partially mediate the relationship between place image and residents' support for sport tourism development. These findings will offer valuable insight to tourism policy makers in crafting an effective sport tourism development plan to gain residents' support for sport tourism development. Theoretical implications and practical implications are discussed, along with limitations and future research.
Concerns regarding the capability of the International Olympic Committee to address doping in sport catalyzed the formation of the World Anti-Doping Agency (WADA) in 1999. In its establishment phase, ...WADA sought geopolitical legitimacy and support from governments (including non-Western states) for financing and acceptance. Africa was not considered during WADA's creation, relegating African states to a passive role in the global anti-doping program, and yet is still subject to the strict compliance requirements for WADA's global policy. African countries face challenges establishing anti-doping support structures and implementing the universal policy, including competing macro-level policy demands that favor addressing legacies of colonialism and human capacity development. To develop robust anti-doping support structures, African nations must spearhead anti-doping initiatives by leveraging existing infrastructure and encouraging collaborations between NADOs such that capacity can be built for policy implementation.
Purpose
The purpose of this study was to report the mid-to-long-term return to sports after all-inside meniscal repair in competitive football players.
Methods
All football players undergoing ...all-inside meniscal repair with a minimum Tegner activity score of 9 and minimum follow-up of 5 years were eligible for inclusion. Patients were excluded if: (a) they had ipsilateral or contralateral: meniscectomy, posterior cruciate ligament tear, multi-ligament knee injuries, osteotomies, or meniscal transplant (b) they had meniscal tears in the anterior horn, and (c) they had bucket-handle tears. All patients included were contacted by phone and asked for current sport status or Tegner score. Preoperative Tegner scores were collected from the medical charts.
Results
All patients (
n
= 29) were men with a median (range) age of 27 (18–37) years and a follow-up of 6 (5–8) years. All meniscal injuries were complete and longitudinal tears. The median preinjury Tegner activity score was 9 (range 9–10). Two patients required revision arthroscopy (6.7 %) with partial meniscectomy before being able to return to competitive football due to suture failure. Twenty-six patients (89.6 %) returned to the same level of competition after recovering from surgery. At the last follow-up, 13 patients (45 %) were able to continue playing football at any level, and 8 (28 %) of them were able to return to the same pre-injury competitive level. The main reasons for the decreased level of activity (from competitive to recreational) or to give up football were job-related or changes in their personal life situation, but were not related to knee or meniscal disorders. Fourteen patients underwent meniscal repair alone, whereas 15 patients had an associated ACL reconstruction procedure. There were no significant differences in the collected variables between both subgroups.
Conclusions
All-inside meniscal repair allows for excellent results with regard to return-to-play rates in competitive football. However, only half of the patients are still playing football in the mid-to-long-term follow-up, although reasons to give up football are not related to knee or meniscal disorders.

Performance analysis research in association football has recently cusped a paradigmatic shift in the way tactical behaviours are studied. Based on insights from system complexity research, a growing ...number of studies now analyse tactical behaviours in football based on the collective movements of team players.
The aim of this systematic review is to provide a summary of empirical research on collective tactical behaviours in football, with a particular focus on organising the methods used and their key findings.
A systematic search of relevant English-language articles was performed on one database (Web of Science Core Collection) and one search engine (PubMed), based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. The keywords 'football' and 'soccer' were each paired with all possible combinations of the following keywords: 'collective movement behaviour', 'collective behaviour', 'tactical behaviour', 'interpersonal coordination', 'space', 'Voronoi', 'synchronisation', 'tactical analysis', 'constraints', 'ecological dynamics', and 'dynamic positioning'. Empirical studies that were related to tactical analyses of footballers' positional data were sought for inclusion and analysis.
Full-text articles of 77 studies were reviewed. A total of 27 tactical variables were identified, which were subsequently organised into 6 categories. In addition to conventional methods of linear analysis, 11 methods of nonlinear analysis were also used, which can be organised into measures of predictability (4 methods) and synchronisation (7 methods). The key findings of the reviewed studies were organised into two themes: levels of analysis, and levels of expertise.
Some trends in key findings revealed the following collective behaviours as possible indicators of better tactical expertise: higher movement regularity; wider dispersion in youth players and shorter readjustment delay between teammates and opponents. Characteristic behaviours were also observed as an effect of playing position, numerical inequality, and task constraints. Future research should focus on contextualising positional data, incorporating the needs of coaching staff, to better bridge the research-practice gap.
Despite the influence and power that the media hold and the importance placed on the role that they can assume regarding corruption, little is known about the part the media can play in corruption in ...sport and any challenges they might face in reporting on it. This study aims to shed light on this unexplored area, by using insights from members of the media based in three Balkan countries, to help uncover the challenges and obstacles faced by sport media. The findings of this study allow for the multifold role of the media in sport corruption to be examined, while uncovering the internally and externally driven obstacles they face, ranging from personal greed to market-based pressures and media’s ostracism by the wider anti-corruption system.
Studies in several sports have shown the benefits of adapting the playing environment to fit junior players. Frequently the changes are pragmatic choices based on space constraints or existing line ...markings, or the result of simple scaling based on stature. In this study, a method of scaling the cricket pitch length is presented which is based on the age-specific size and performance of the bowlers and batters. The objective was a pitch length which enabled young bowlers to bowl good length deliveries while releasing the ball at a more downward angle, similar to elite bowlers. The steeper release angle has the benefit of reducing the sensitivity of the ball flight distance to the variability of ball release. Based on data from county standard under-10 and under-11 players a pitch length of 16.22 yards (14.83 m) was calculated, 19% shorter than previously recommended for under-11s in England. A shorter pitch also increases the temporal challenge for batters, encouraging a wider variety of shots and improved anticipation skills. Pitch lengths scaled in this way to fit the players' abilities as they develop will enable a more consistent ball release by bowlers and more consistent temporal demand for batters.
The maturation of the field of ‘Sport for Development and Peace’ (SDP) is reflected in the growing number of research publications on the topic. This article focuses on a recent review of ...English-language research publications on SDP from 2000–2014 conducted by Schulenkorf et al. (2016. Sport for development: an integrated literature review. Journal of Sport Management 30: 22–39). We attempt to extend the analysis of current SDP research offered by Schulenkorf et al. through an exploration of the sociological implications of their key findings. In particular, we offer critical sociological commentary on key insights regarding the conceptualization of SDP; the dominant theoretical perspectives used in SDP research; the methodology and dissemination of SDP research and the demographics of researchers and research teams. In so doing, we seek to encourage critical reflection and practical considerations for scholars interested in the critical sociological analysis of SDP.
Natural language processing (NLP) has been studied in computing for decades. Recent technological advancements have led to the development of sophisticated artificial intelligence (AI) models, such ...as Chat Generative Pre-trained Transformer (ChatGPT). These models can perform a range of language tasks and generate human-like responses, which offers exciting prospects for academic efficiency. This manuscript aims at (i) exploring the potential benefits and threats of ChatGPT and other NLP technologies in academic writing and research publications; (ii) highlights the ethical considerations involved in using these tools, and (iii) consider the impact they may have on the authenticity and credibility of academic work. This study involved a literature review of relevant scholarly articles published in peer-reviewed journals indexed in Scopus as quartile 1. The search used keywords such as "ChatGPT," "AI-generated text," "academic writing," and "natural language processing." The analysis was carried out using a quasi-qualitative approach, which involved reading and critically evaluating the sources and identifying relevant data to support the research questions. The study found that ChatGPT and other NLP technologies have the potential to enhance academic writing and research efficiency. However, their use also raises concerns about the impact on the authenticity and credibility of academic work. The study highlights the need for comprehensive discussions on the potential use, threats, and limitations of these tools, emphasizing the importance of ethical and academic principles, with human intelligence and critical thinking at the forefront of the research process. This study highlights the need for comprehensive debates and ethical considerations involved in their use. The study also recommends that academics exercise caution when using these tools and ensure transparency in their use, emphasizing the importance of human intelligence and critical thinking in academic work.
