Athletic Performance & Muscle

1

To evaluate Rhaponticum carthamoides extract on muscle mass and strength in trained athletes

1992 48 participants 8 weeks 300 mg/day Rhaponticum extract
Human Study RCT Double-Blind Placebo Positive

Study Type

Randomised, double-blind, placebo-controlled

Purpose

To evaluate Rhaponticum carthamoides extract on muscle mass and strength in trained athletes

Dose

300 mg/day Rhaponticum extract

Participants

48 trained athletes

Duration

8 weeks

Results

Significant increase in lean body mass (+1.3 kg, p=0.04) and strength vs placebo. Testosterone:cortisol ratio maintained. No hormonal changes detected (non-steroidal mechanism).

How They Measured It

Lean body mass, 1RM strength, anabolic hormone profile

2

To evaluate ecdysterone (from Rhaponticum) on body composition and strength

2019 46 participants 10 weeks 48 mg/day ecdysterone (purified from Rhaponticum)
Human Study RCT Double-Blind Placebo Positive

Study Type

Randomised, double-blind, placebo-controlled

Purpose

To evaluate ecdysterone (from Rhaponticum) on body composition and strength

Dose

48 mg/day ecdysterone (purified from Rhaponticum)

Participants

46 male athletes

Duration

10 weeks

Results

Significant increase in lean body mass vs placebo (p=0.038). Muscle strength improved. Ecdysterone activated estrogen receptor beta signalling, promoting anabolic effects. No androgenic activity.

How They Measured It

Lean body mass (DEXA), 1RM bench press, protein synthesis markers
