The Claim

Increases in biceps brachii muscle thickness are significantly negatively correlated with decreases in radial deformation (Dm) measured by tensiomyography (r = -0.763, Adj.R² = 0.560), indicating that Dm may serve as a non-invasive indicator of muscle hypertrophy in untrained individuals.

What the research says

Supports is higher

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

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

In untrained individuals, as the biceps muscle gets thicker, the radial deformation measured by tensiomyography decreases in a predictable way, suggesting this measurement can detect muscle growth without invasive procedures.

See the scientific wording

A significant negative correlation exists between increases in biceps brachii muscle thickness and decreases in radial deformation (Dm) measured by tensiomyography (r = -0.763, Adj.R² = 0.560), suggesting that Dm may serve as a non-invasive indicator of muscle hypertrophy in untrained individuals.

Why this might work

When muscle fibers grow larger from training, the muscle becomes denser and stiffer, so when it's tapped with a quick electrical pulse, it doesn't bulge out as much as it did before.

    When people train their biceps and the muscles get bigger, the way the muscle bulges when zapped with electricity gets smaller — and this change is a good way to tell how much muscle they gained, without needing scans or needles.
