This literature is, however, delinked from current research on performance and image enhancement drugs (PIEDs) use, part of which has explored how PIEDs consumption is implicated in the production and reproduction of masculinities. This study merges these two literatures to explore how young men constitute masculinity through non-medical tramadol use for performance enhancement, highlighting the political-economic and socio-cultural contexts that shape and rationalize this consumption. It draws insights from the works of Judith Butler, Michel Foucault and Bruno Latour to inform analysis of 39 in-depth interviews with young men who consume tramadol non-medically in Nigeria. Accounts counter discourses of non-medical tramadol consumption that emphasize harmfulness, enacting this consumption as ‘technologies of the self’, practices through which consumers defined themselves as men. They further highlight how tramadol consumption for sexual and work performance enhancement is veridicted within its ‘modes of existence’, namely the economic conditions and cultural norms that shape how young men perform masculinity. The study questions contemporary approaches that aim to prevent the negative consequences of non-medical tramadol consumption through penalization. Although it is important to emphasize the potential negative consequences of non-medical tramadol consumption, it is equally necessary to understand that harms and benefits constitute a knot of experience, rather than mutually-exclusive phenomena. Recognizing, and attending to, the complexities of non-medical tramadol consumption invites collaborative interventions that harness the knowledge and safe consumption practices of consumers.</div></div>","PeriodicalId":19886,"journal":{"name":"Performance enhancement and health","volume":"13 3","pages":"Article 100339"},"PeriodicalIF":2.9,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821410","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}

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> < .001) and well-being (<em>B</em> = –0.19, <em>p</em> < .001). It can be concluded that during a nine-week period of PWL female powerlifters reported improvements in weight satisfaction and well-being.

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}
