Anti-doping control refers to the formal process of testing athletes for banned performance substances. Officials collect biological samples to ensure every lifter competes on a fair playing field. This system maintains the integrity of the sport and protects the health of participants. A technician monitors a lifter during a random urine test at a national competition. Athletes must provide their location details to testing agencies throughout the entire calendar year. Strict adherence to these rules prevents disqualification from major international weightlifting events.
