Anabolic androgenic steroids (AAS) are used by some athletes to enhance performance despite the health risk they may pose in some persons. This work was carried out to evaluate the possible structural and functional alterations in the heart using two-dimensional, M-mode, tissue Doppler imaging (TDI) and strain rate imaging (SRI) in athletes using supraphysiological doses of AAS. Additionally, t...

BACKGROUND To date, no studies document the effect of anabolic steroids on rotator cuff tendons. STUDY DESIGN Controlled laboratory study. HYPOTHESIS Anabolic steroids enhance remodeling and improve the biomechanical properties of bioartificially engineered human supraspinatus tendons. METHODS Bioartificial tendons were treated with either nandrolone decanoate (nonload, steroid, n = 18), ...
