Study 1
Study type:
Non-randomised placebo-controlled clinical trial
Purpose:
To measure the effects of ecdysteroids (ecdysterone) on sports performance and body composition.
Interventions:
Ecdysterone supplement and 3 sessions of resistance training per week
Participants:
46 young men with at least 1 year of experience in weight-lifting (bench press, deadlift and squat)
Duration:
10 weeks
Results:
Compared to the placebo group, ecdysterone was correlated with significantly larger increases in muscle mass. The placebo group actually lost muscle mass.
Ecdysterone supplementation was also correlated with a significant increase in bench press and squat performance compared to the placebo group.
Importantly, biomarkers for liver or kidney toxicity did not increase after ecdysterone supplementation.
