SOURCE-LINKED STUDY SUMMARY

Effects of androgenic-anabolic steroids on neuromuscular power and body composition.

Journal of applied physiology: respiratory, environmental and exercise physiology ·

Human

What was studied?

A double-blind, repeated-measures study compared testosterone cypionate, nandrolone decanoate, and placebo for neuromuscular power and body composition, with treatment order counterbalanced.

What changed?

Peak torque did not change significantly between treatments in 7 of 10 joint actions. Lean mass and body-fat differences were not significant; remaining torque changes showed no consistent pattern. Participants nevertheless reported feeling stronger after anabolic agents.

Who was studied?

Nine volunteers experienced in progressive-resistance weight training participated. They continued training, received supplemental protein, and kept dietary records throughout the study.

Studied exposure

Each testosterone, nandrolone, or sesame-oil placebo condition lasted three weeks. The abstract does not report doses, administration route, or frequency.

What remains uncertain?

Study limitations were not stated in the abstract. Methodological quality has not been appraised.
