Bohlin KP, Pohanka A, Andersson A, Villén T, Ekström L. Detection of anabolic agents including selective androgen receptor modulators in samples outside of sport. Drug Test Anal 2024; 16:827-834. [PMID: 37986708 DOI: 10.1002/dta.3600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 10/16/2023] [Accepted: 10/21/2023] [Indexed: 11/22/2023]
Abstract
Selective androgen receptor modulators (SARMs) are prohibited by the World Anti-Doping Agency (WADA) since 2008. Similarly, to anabolic androgenic steroids (AAS), SARMs are detrimental to health not only in athletes but also in the general population. However, studies of the occurrence of SARMs outside of sport are scarce. Swedish healthcare samples from the Drugs of Abuse Laboratory at Karolinska were analyzed using WADA-accredited screening methods at the Doping Control Laboratory in Stockholm to estimate the frequency of SARM use outside of the WADA laboratories. Twenty (4%) of the male urine samples (n = 542) were positive for SARMs, whereas none of the analyzed female samples (n = 100) contained any SARMs. The top three SARMs found were LGD-4033 followed by RAD140 and ostarine. Two or more SARMs were found in >50% of the SARM-positive samples. AASs were identified in 40% of samples containing SARMs. A difference between genders was observed where 34% male and 7% female samples contained AAS. Many samples displayed testosterone/epitestosterone values indicative of testosterone intake, without presence of other AAS, and hence, there is a risk that these samples are being falsely reported as negative. Our results indicate that SARM use might be a concern outside of sport. Subsequently, in addition to AAS, the healthcare system should also be informed about SARM abuse and the associated adverse side effects.

Tavares ASR, Carolino E, Teques P, Calmeiro L, Serpa S. Profile of gym-goers who do not use performance-enhancement substances. Front Psychol 2024; 15:1357566. [PMID: 38873513 PMCID: PMC11169804 DOI: 10.3389/fpsyg.2024.1357566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 04/29/2024] [Indexed: 06/15/2024] Open
Abstract
Introduction Currently the use of prohibited performance-enhancing substances (PES) in fitness and gym settings is a public health concern as adverse health consequences are emerging. Understanding the characteristics of gym-goers who do not use these substances could lead to an important complement to the ongoing research about risk factors for PES use. The aim of this study was to identify the profile of PES non-use in gym-goers. Methods In total, 453 gym-goers (mean age = 35.64 years; SD = 13.08 - measure of central tendency location and measure of absolute dispersion, respectively) completed an online survey assessing sociodemographic factors, exercise characteristics, gym modalities, peers, social influence, attitudes, subjective norms, beliefs, intentions, and self-reported use of PES. Results Decision Trees showed that being a woman, training less frequently, not practicing bodybuilding and having a negative intention to consume PES were identified as characteristics of non-users of PES. Discussion These results may support evidence-based anti-doping interventions to prevent abusive use of PES in the fitness context.

Mason J, Starc L, Morin JB, McClelland EL, Zech A. Can the recent sex-specific evolutions in elite running performances be attributed to advanced footwear technology? Front Sports Act Living 2024; 6:1386627. [PMID: 38807616 PMCID: PMC11130513 DOI: 10.3389/fspor.2024.1386627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Accepted: 05/02/2024] [Indexed: 05/30/2024] Open
Abstract
Recent improvements in elite running performances across all distances have been largely attributed to the introduction of advanced footwear technology (AFT), which features a curved and stiff plate working synergistically with a new generation of midsole foams demonstrating enhanced resilience and compliance. These recent improvements appear to be considerably more pronounced in women's events, highlighted by improvements in road racing world records by an average of 3.7% (range: 2.6%-5.2%) compared to mean progressions of 1.5% (range: 1.3%-1.9%) in the same men's events. Although there is a growing body of research investigating the mechanisms underpinning running performance enhancements derived from AFT, there remains no explanation for potential sex-based differences in their benefits. We overview the currently available evidence and highlight why the recent direction of AFT research provides a barrier to progress by focusing primarily on male athletes. We subsequently provide our perspective on why women may be benefiting from the new generation of shoes more than men, suggest potential mechanisms leading to hypotheses that need to be further investigated in upcoming studies, and finally propose that factors outside of footwear innovation may have concurrently driven the recently observed performance evolutions.

Summer Olympic sports and female athletes: comparison of anti-doping collections and prohibited substances detected in Australia and New Zealand vs. France. Front Sports Act Living 2023; 5:1213735. [PMID: 37745202 PMCID: PMC10515209 DOI: 10.3389/fspor.2023.1213735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Accepted: 07/31/2023] [Indexed: 09/26/2023] Open
Abstract
Like any athlete, female athletes may be tempted to use prohibited substances during competition or training to enhance their performance. Anti-doping tests performed on female athletes in summer Olympic sports from two geographical areas: Australia/ New Zealand, and France were compared. First, the distribution of sample collections across different sports disciplines, as well as the distribution of substances was investigated. Then the distribution of collections and substances detected in the five sports categories (Strength/Speed, Endurance, Mixed, Motor Skills with High Energy Expenditure, and Motor Skills with Low Energy Expenditure) were studied with consideration of therapeutic use exemptions obtained by the athlete. Australia/New Zealand and France were similar in their overall number of anti-doping collections performed. Likewise, both regions had the same sports disciplines (athletics, aquatics, cycling) and sport categories (Mixed and Endurance) as having the highest number of sample collections. The Motor Skills with High Energy Expenditure, and Motor Skills with Low Energy Expenditure categories had the lowest number of sample collections. However, the number of substances detected was significantly different (p < 0.05) with a greater number of substances found in the French data. There were a few substances in common between the two geographical areas, namely prednisone/prednisolone, carboxy-THC, terbutaline, vilanterol and methylphenidate, but most were different. In-competition tests were the category where most of the AAFs were found.

Abstract
Also in 2021/2022, considerable efforts were invested into advancing human sports drug testing programs, recognizing and taking into account existing as well as emerging challenges in anti-doping, especially with regard to substances and methods of doping specified in the World Anti-Doping Agency's 2022 Prohibited List. In this edition of the annual banned-substance review, literature on recent developments published between October 2021 and September 2022 is summarized and discussed. Focus is put particularly on enhanced analytical approaches and complementary testing options in human doping controls, appreciating the exigence and mission in anti-doping and, equally, the contemporary "new normal" considering, for example, the athlete's exposome versus analytical sensitivity and applicable anti-doping regulations for result interpretation and management.
