Final answer:
Yes, athletes are allowed to have a representative accompany them to the doping control station after being selected for doping control. The presence of a representative helps assure the protection of the athlete's rights during the doping control process.
Step-by-step explanation:
Once an athlete is notified of their selection for doping control at a competition, they are indeed allowed to have a representative accompany them to the doping control station. This is to ensure the athlete's rights are protected and to assist with the doping control process. It's important to note that doping regulations are implemented to maintain the integrity of sports and the health of the athletes. Testing for banned substances began in a structured manner in the late 1960s with organizations like FIFA and the IOC joining the movement initiated by IAAF to combat doping. Since the turn of the century, with the establishment of the World Anti-Doping Agency (WADA), the efficiency of catching drug cheats has increased significantly.
