Muscle wasting in space is primarily driven by depressed protein synthesis rather than excessive protein breakdown, and anabolic steroids are ineffective without concurrent resistance exercise.
To prevent muscle loss in space, resistance exercise is essential. Anabolic steroids may help but are weak alone and only effective when combined with strength training. The primary countermeasure remains physical exercise.
ModerateQualifiesMEDIUM confidence
muscle wasting in space is primarily due to depressed protein synthesis... Even though this might theoretically be countered by the synthesis-boosting effects of anabolic steroids, the practical grounds for such recommendation are currently weak. Moreover, they reveal their full potential only when combined with an anabolic exercise stimulus, for example, via strength training.
Why this rating
Based on ground-based bed rest studies and theoretical spaceflight analogues.
