The Claim

Training status (trained vs. untrained) does not significantly moderate the effect of resistance training velocity on strength adaptations, with both subgroups showing small, non-significant effects favoring fast training.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports
52score
Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Whether you're new to lifting weights or experienced, how fast you lift doesn't really change how much stronger you get. Both groups got a tiny bit stronger with fast lifting, but it wasn't a clear or big difference.

See the scientific wording

Training status (trained vs. untrained) does not significantly moderate the effect of resistance training velocity on strength adaptations, with both subgroups showing small, non-significant effects favoring fast training (untrained: Hedges' g = 0.22, p = 0.09; trained: Hedges' g = 0.26, p = 0.29), based on 4 trained and 20 untrained studies.

What the research says

1 study
  1. Study: Intentionally Slow Concentric Velocity Resistance Exercise and Strength Adaptations: A Meta-Analysis

    The study looked at fast vs. slow weight training and found that whether you're trained or untrained doesn't change which is better for strength, just like the claim said.
