Researchers investigating PWL among powerlifters have identified associations to psychological outcomes. Yet investigations considering the psychological outcomes of PWL can be expanded to include (1) broader conceptualizations of psychological concepts and (2) greater nuance for the dynamics of PWL. Moving towards addressing these research gaps, the purpose of this study was to examine body image and well-being in female powerlifters during a period of PWL surrounding competition. Using a non-experimental longitudinal design, female powerlifters (<em>N</em> = 12; <em>Mage</em> = 29.42, <em>SD</em>age = 9.23 years) self-reported body weight, body image, and well-being at five timepoints over 10 weeks. Body image was measured using the Body Appreciation Scale-2 along with a single-item indicator of shape and weight satisfaction. Well-being was measured using the Warwick Edinburgh Mental Well-Being Scale. At the time of official competition weigh-in, participants lost an average of 3.44 kg of body weight (<em>SD</em> = 1.14 kg). One pooled time series regression analysis was used per response variable (body appreciation/shape satisfaction/weight satisfaction/well-being) to test the temporal association with body weight. Body weight predicted weight satisfaction (<em>B</em> = 0.40, <em>p</em> &lt; .001) and well-being (<em>B</em> = –0.19, <em>p</em> &lt; .001). It can be concluded that during a nine-week period of PWL female powerlifters reported improvements in weight satisfaction and well-being. These findings help to understand psychological outcomes for gradual weight loss practices among female powerlifters when preparing to compete.</div></div>","PeriodicalId":19886,"journal":{"name":"Performance enhancement and health","volume":"13 2","pages":"Article 100333"},"PeriodicalIF":2.9,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, the academic field seldom draws on the voices of those affected when considering doping in sport. Our aim was to illuminate important aspects of sanctioned athletes’ experiences and highlight opportunities for prevention and rehabilitation. <em>Design:</em> A semi-structured interview research design was used, and data informed the development of composite vignettes, a form of creative non-fiction. <em>Method:</em> Semi-structured interviews were conducted with two elite rugby players sanctioned for violating the anti-doping rules within rugby league (<em>n</em> = 1) and rugby union (<em>n</em> = 1). Three composite vignettes were created illuminating player experiences before, during and after the violations. <em>Findings:</em> The vignettes highlight in participants’ own words the multiple impacts of sport demands and drug use: (1) <em>Leading up to the violation: ‘You're just treading water, you're surviving’</em> (2) <em>‘There's just this massive amount of social pressure in rugby, not just on the game, but on who you're supposed to be’</em> (3) <em>‘It was like being hit by a train’.

Amid these issues lies a less recognized yet crucial issue of epistemic racism, which can undermine global anti-doping initiatives. Epistemic racism, rooted in culturally biased systems of knowledge production, often privileges Western perspectives while relegating non-Western perspectives. Such bias can perpetuate racial stereotypes and affect anti-doping research and policy implementation. This Commentary explores the concept of epistemic racism, its manifestations, and strategies for mitigation within anti-doping research. A case example of a recent publication is presented to demonstrate how epistemic racism can go undetected and unchallenged, potentially reproducing and reinforcing outdated stereotypes. Overlooked, epistemic racism can have profound ramifications, including deterring aspiring scholars from developing countries, distorting anti-doping policies, and reinforcing racial stereotypes. To counteract this, it is essential to educate researchers on racial biases, adapt methodologies to reduce these biases and increase the inclusion and representation of scholars from developing countries in research and editorial roles. Such measures may foster a more inclusive research environment and directly inform practice, helping anti-doping research and practice become more critically aware.</div></div>","PeriodicalId":19886,"journal":{"name":"Performance enhancement and health","volume":"13 1","pages":"Article 100300"},"PeriodicalIF":2.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143394928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We address our critics through three reflective sections on method, racism, and context.

In the second section, we reflect on racism. Far from being a novel concept, epistemic racism has been acknowledged across disciplines, making it relevant for anti-doping scholarship. Moreover, we challenge its dismissal as irrelevant and note that systemic racial biases in knowledge production have long shaped science and policy. Hence, our recommendation for scholars to be racially aware seems pertinent given the academia's ongoing failure to eradicate racial biases. This is further supported by the observation that the recommendation for editorial board representation was assumed tokenism. The third section focuses on context – a term heavily leaned upon but inconsistently and questionably used. We note how the original framing of athletes from developing countries lacking choice, values, and morality was obscured in favor of a new framing that paints the original work as a positive connotation of these athletes. We critique the concept of self-selection bias as a form of blame-shifting that ignores the historical context and consequences of colonialism.

Though the issue is well known, there are key knowledge gaps regarding the role of different stakeholders both in creating and managing unintentional doping. The current study aimed to identify the influential tasks and stakeholders within the Australian sport system that are associated with supplements. A Hierarchical Task Analysis (HTA) was developed during a subject matter expert workshop (n = 12) to decompose the supplement use in sport ‘system’ into a hierarchical structure of goals, sub-goals, operations, and plans. A task network was developed during the SME workshop and based on the first level sub-goals of the HTA. Network analysis was then applied to determine the interdependency and influence of system tasks and stakeholders. Network metrics included Density, Out-degree centrality, In-degree centrality, Betweenness centrality, Closeness centrality, and Eigenvector centrality. In total, 15 first level sub-goals were identified which were further decomposed into 71 sub-goals and operations. The overall identified goal of athletes taking supplements was to optimise health, performance, recovery, image, and achieve optimal weight. Within this overall goal, numerous tasks are required to be performed including research, manufacturing and regulation of supplements, maintaining clean sport, to the administration of supplements by athletes, to subsequent assessments of their efficacy. The most influential tasks within the system include ‘maintaining clean sport’ by anti-doping authorities, and ‘marketing/advertising’ of supplements by supplement companies. Influential stakeholders within the system included ‘anti-doping agencies’, ‘athlete support personnel’, and ‘sponsors’. The analysis has demonstrated that multiple and varied stakeholders have specific roles to play in preventing unintentional doping. The findings suggest that for the prevention of unintentional doping through supplement use, interventions will need to shift away from the typical focus on athletes and athlete support personnel, to encompass a broader systemic focus.</div></div>","PeriodicalId":19886,"journal":{"name":"Performance enhancement and health","volume":"13 1","pages":"Article 100317"},"PeriodicalIF":2.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
