Physiological Basis of Sex Differences in Human Performance and Exercise‐Associated Pathology

Clinical Endocrinology, EarlyView.
ABSTRACT The presence of sex differences in human physical performance is well‐established and shaped by distinct endocrine, anatomical and physiological mechanisms. Despite sustained advances, our understanding of how inherent biological factors drive variations in exercise capacity and related pathologies is still developing.

Metabolism of anabolic androgenic steroids [PDF]

Clinical Chemistry, 1996
Abstract Anabolic androgenic steroids (AAS) are misused to a high extent in sports by athletes to improve their physical performance. Sports federations consider the use of these drugs in sports as doping. The misuse of AAS is controlled by detection of the parent AAS (when excreted into urine) and (or) their metabolites in urine of ...

Statistical Discrimination of Urinary Steroid Biomarkers in the Athlete Biological Passport: A Novel Approach to an Abnormal Steroid Profile Score (ASPS)

Drug Testing and Analysis, Volume 18, Issue 5, Page 608-618, May 2026.
The study developed a single Abnormal Steroid Profile Score (ASPS) to improve interpretation of the Athlete Biological Passport steroid module. Using Bayesian modelling and logistic regression, biomarker patterns from laboratory and doping control data successfully discriminated between doped and clean individuals, with improved classification ...
