The world of women’s professional cycling is grappling with a rare doping case, as Italian rider Linda Laporta has been provisionally suspended after testing positive for the banned substance ostarine. The news, confirmed by the International Testing Agency (ITA) on Friday, casts a shadow over the rapidly growing sport and raises questions about the ongoing fight against doping in women’s athletics. This case marks a significant moment, as positive tests remain relatively infrequent in the women’s peloton compared to the men’s.
Laporta, 26, who rides for the Vini Fantini-BePink continental team, provided the positive sample during an “intelligence-led testing” mission at the UAE Tour Women on February 5, according to the ITA. The substance identified was enobosarm, more commonly known as ostarine, a selective androgen receptor modulator (SARM). Ostarine is prohibited under the World Anti-Doping Agency (WADA) rules as a S1.2 class anabolic agent. The ITA’s announcement comes as the agency has taken over the anti-doping program for the Union Cycliste Internationale (UCI) as of 2026.
What is Ostarine and Why is it Banned?
Ostarine, while sometimes researched for potential therapeutic uses like treating muscle wasting and osteoporosis, is banned in sports due to its performance-enhancing effects. According to the ITA, the substance is known to increase lean body mass and promote muscle growth. These effects provide an unfair advantage to athletes who use it, violating the principles of fair play. SARMs like ostarine work by selectively binding to androgen receptors in the body, mimicking some of the effects of testosterone without the same level of side effects, though long-term health consequences are still being studied. The use of such substances is a direct violation of anti-doping regulations designed to ensure a level playing field for all competitors.
A Rare Occurrence in Women’s Cycling
While doping remains a concern across all levels of professional cycling, positive tests in the women’s peloton have been comparatively rare. Data from the Movement for Credible Cycling (MPCC) shows that in 2025, only one of the 20 recorded doping cases among professional cyclists involved a woman. This makes Laporta’s case particularly noteworthy, prompting scrutiny and a renewed focus on anti-doping efforts within the sport. The MPCC is an independent organization that promotes a higher standard of anti-doping practices in cycling.
Laporta’s Career and the Provisional Suspension
Laporta turned professional in 2024 and has yet to achieve a professional race victory. She finished 50th overall at the UAE Tour Women, the race where the sample was collected. Following the adverse analytical finding, a mandatory provisional suspension has been imposed under UCI anti-doping rules. This means Laporta is currently barred from competing in any sanctioned cycling events. She has been formally notified of the positive test and has the right to request analysis of her “B-sample” – a second test of the same sample – to verify the initial finding.
The process allows Laporta to challenge the result and potentially clear her name. If the B-sample confirms the presence of ostarine, or if she chooses not to request analysis of the B-sample, the case will proceed as a confirmed anti-doping rule violation. The potential consequences of a confirmed violation could include a lengthy ban from competition, potentially jeopardizing her career.
What Happens Next?
As of Friday afternoon, neither Laporta nor her team, Vini Fantini-BePink, had issued a public statement regarding the positive test. The team has not responded to requests for comment. The next step in the process is awaiting Laporta’s decision regarding the B-sample analysis. The ITA will then proceed based on her response, either confirming the violation and initiating a disciplinary process or clearing her name if the B-sample is negative. The disciplinary process, if initiated, will be overseen by the UCI and could involve further investigation and a hearing.
This case serves as a stark reminder of the ongoing challenges in maintaining the integrity of professional cycling. The ITA’s commitment to “intelligence-led testing” suggests a proactive approach to detecting doping, focusing on targeted testing based on risk assessment. The agency’s role in overseeing the UCI’s anti-doping program is crucial in ensuring a fair and clean sport for all athletes.
The cycling community will be closely watching the developments in this case, as it has the potential to significantly impact the sport and its reputation. The outcome will undoubtedly influence future anti-doping strategies and reinforce the importance of vigilance in protecting the integrity of competition.
