SOURCE-LINKED STUDY SUMMARY
Effects of androgenic-anabolic steroids on neuromuscular power and body composition.
Abstract summarizedQuality not appraised
- 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.
- Who / model studied
- Nine volunteers experienced in progressive-resistance weight training participated. They continued training, received supplemental protein, and kept dietary records throughout the study.
- Studied dose & schedule
- Each testosterone, nandrolone, or sesame-oil placebo condition lasted three weeks. The abstract does not report doses, administration route, or frequency.
- What the study found
- 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.
- Limitations & context
- Study limitations were not stated in the abstract. Methodological quality has not been appraised.
