What was compared
Fifty-seven men with little resistance-training experience were randomized to root extract or placebo. Both groups followed an eight-week resistance-training program. [1]
The extract group had greater gains in bench-press and leg-extension strength, along with differences in selected secondary measurements. These findings concern novice trainees and the study’s particular preparation. [1]
Limits of the result
The experiment did not compare several doses, so it cannot identify the best daily amount. It also cannot predict the same effect in highly trained athletes or without exercise. Funding and conflicts were not established from the abstract. [1]
A hypothetical distinction
Imagine both groups train and become stronger, with a larger average gain in one group. The supplement comparison concerns the additional difference; it does not mean all gains in that group came from the supplement.
| Detail | Interpretation |
|---|---|
| 57 randomized | Novice male trainees |
| Training in both arms | Shared intervention |
| Dose comparison | Not performed |
