Evidence for the Effectiveness of the Performance Passport Within an Intelligence‐Based Weightlifting Anti‐Doping Programme

Drug Testing and Analysis, EarlyView.
Anti‐doping programmes require efficient testing, as biological testing is costly; the Athlete Performance Passport (APP) uses performance data to identify at‐risk athletes alongside APMU and ABP methods. Since the introduction of the steriodal passport in 2014, the APP outperformed APMU (17%) and ABP steroidal profiles (10%) with 30% detection ...
