Anabolic steroids increase all of the following EXCEPT:muscle massstrengthfat-free massmuscle endurance

Anabolic steroids increase all of the following EXCEPT:

1. Muscle mass: Anabolic steroids are known to significantly increase muscle mass by promoting protein synthesis and muscle cell growth.

2. Strength: These steroids also enhance strength by increasing muscle size and improving the efficiency of muscle contractions.

3. Fat-free mass: Anabolic steroids contribute to an increase in fat-free mass, which includes muscle, bone, and other non-fat tissues.

4. Muscle endurance: While anabolic steroids improve muscle mass and strength, they do not significantly increase muscle endurance. Muscle endurance is the ability of a muscle to sustain repeated contractions over a period of time, and it is more influenced by cardiovascular and muscular endurance training rather than anabolic steroids.

Therefore, the correct answer is muscle endurance.
