Exciting Weekend for Sports Fans
This weekend promises to be an exciting one for sports enthusiasts around the world. The World Aquatics Championships in Singapore are entering their third weekend of competition, while the prestigious Tour de France is set to conclude on Sunday, marking the end of one of cycling’s most iconic events. To cap off the weekend, the UEFA Women’s EURO 2025 final will take place on Sunday evening in Basel, Switzerland, with world champions Spain facing European champions England.
These three major events span different sports and locations, but they share a common thread: the fight against doping. Athletes competing in these events are under strict monitoring to ensure that banned substances are not used, maintaining the integrity of the competitions.
The Complexities of Anti-Doping
In recent episodes of the Tech Talks podcast, the challenges faced by anti-doping authorities have been explored in depth. These include the difficulty in detecting performance-enhancing drugs and the reasons why some athletes turn to them. But what are the health risks associated with these substances?
Key Points About Doping and Health
-
Not All Banned Substances Pose Immediate Health Risks
A substance may be banned even if it does not directly harm health. According to the World Anti-Doping Agency (WADA), drugs must meet at least two of three criteria: enhancing performance, posing a health risk, or violating the spirit of sport. This means some substances may only be banned for ethical or competitive reasons. -
Research Challenges in Doping
Researching doping is complex due to ethical constraints. For example, researchers cannot administer high doses of banned substances to study participants because of potential health risks. This makes it difficult to fully understand the long-term effects of these substances.

Recent Developments in Doping Research
Studies on doping are relatively new, and many of the substances used by athletes are also new, making it challenging to assess their long-term impacts. This lack of historical data complicates efforts to evaluate health risks accurately. -
Health Dilemmas
Establishing a clear cause-and-effect relationship between drug use and health outcomes is complicated. Factors such as genetics and environmental influences often play a role, making it hard to isolate the effects of specific substances. -
Difficulty in Identifying Effects
Athletes often use multiple banned substances, which can make it difficult to determine the individual health effects of each. This complexity further complicates the assessment of long-term risks.
Common Performance-Enhancing Drugs and Their Risks
Anabolic Steroids
Anabolic steroids are among the most well-documented doping substances. They are commonly used in sports like sprinting and weightlifting to increase muscle mass and strength. A notable case involved tennis player Jannik Sinner, who tested positive for steroids in 2024 and received a three-month ban.
Steroids can lead to serious health issues, including heart enlargement and reduced brain volume. Researchers have found that these changes may persist over time, though the full implications are still being studied.
Erythropoietin (EPO) and Blood Doping
EPO is a hormone that boosts red blood cell production, improving endurance. It is frequently used in endurance sports like cycling and marathons. Blood doping involves removing and re-transfusing blood to increase red blood cell count, which can enhance performance.
Lance Armstrong, a former cyclist, admitted to using EPO in 2013. While EPO and blood doping are linked to cardiovascular risks such as blood clots and heart attacks, the connection is not always straightforward. Some claims about deaths linked to EPO have been disputed by later studies, highlighting the need for careful analysis.
Beta Blockers
Beta blockers are less well-known than other performance-enhancing drugs but are banned in sports like archery and shooting. They help reduce heart rate and anxiety, aiding focus. North Korean shooter Kim Jong-su tested positive for beta blockers during the 2008 Beijing Olympics.
Common side effects include fatigue, dizziness, and nausea. Long-term use has been linked to an increased risk of Parkinson’s disease, although research on this specific link remains limited.
