In 1999, the sports world experienced a significant change. On November 10, the World Anti-Doping Agency (WADA) was founded with the goal of “protecting athletes, promoting clean sport values, and upholding the spirit of sports globally.”
WADA was established in response to various high-profile drug-related incidents, such as Ben Johnson’s steroid scandal in the 1988 Olympics and the 1998 “Festina Scandal” involving drugs found in a team car at the Tour de France. It was created out of concern for athlete safety and the potential backlash from audiences towards professional sports.
The WADA Code includes an annual publication of a Prohibited List, which outlines banned substances and methods for both in-competition and out-of-competition use. A substance or method is considered prohibited if it meets two out of three criteria – it may enhance performance, poses health risks to athletes, or goes against the spirit of sport.
This framework aims to create a safer environment for athletes but also presents a grey area where certain substances or methods could be legal but potentially illegal in the future.
As a result, there is ongoing investigation into legal methods and substances commonly used by professional athletes that may face bans in the future.
1. Carbon monoxide rebreathing
With more than 100 deaths annually in the UK due to carbon monoxide poisoning, the use of carbon monoxide rebreathing in sports science may raise eyebrows. However, this method is commonly used to measure hemoglobin levels in athletes.
Through carbon monoxide rebreathing, athletes inhale the gas to measure various blood parameters, particularly hemoglobin content, which impacts oxygen delivery to muscles. This process simulates the effects of training at high altitudes, where athletes produce more red blood cells to enhance performance.
While this method has its benefits, prolonged exposure to carbon monoxide can have adverse effects on an athlete’s oxygen-carrying capacity, leading to concerns about its use.
2. Oxygen Tent
Similar to carbon monoxide rebreathing, oxygen tents are popular among athletes to simulate high-altitude environments and enhance red blood cell counts. These tents have been used by various sports teams and athletes to improve performance through altitude training.
Despite its benefits, the use of oxygen tents has stirred controversy in the past due to concerns about artificially elevated blood parameters and its impact on the spirit of sports. Regulations and bans have been enforced in some regions to address these issues.
3. High-tech trisuit
Modern trisuits, like the one worn by British triathlete Alex Yee at the Paris Olympics, incorporate cutting-edge technology to enhance performance. These suits are designed to optimize aerodynamics, improve speed, and potentially provide advantages in water sports.
With innovations in fabric technology and fit, these trisuits are custom-made to maximize performance while complying with sports regulations. The use of advanced materials and design elements can influence race outcomes significantly.
4. Ketone Drinks
Ketone drinks have gained popularity among athletes for their potential to boost energy levels without the need for starvation. These drinks can help conserve glycogen reserves during intense exercise, improve endurance, and enhance recovery between workouts.
Despite their benefits, the use of ketone drinks raises concerns about their long-term effects on health and athletic performance. Organizations like the Movement for Credible Cycling (MPCC) advocate against the use of ketones due to insufficient research and potential risks associated with their consumption.
5. Caffeine
Caffeine remains a popular dietary supplement among athletes due to its proven performance-enhancing effects. Studies have shown that caffeine can improve fat burning, speed, and endurance by stimulating neuronal activity in the brain and triggering the release of adrenaline.
While caffeine is legal and widely used, there are concerns about its safety when consumed in excessive amounts. Regulations on caffeine use have evolved over time, with bans being implemented and lifted based on scientific evidence and health considerations.
