The Claim

Surface electromyography combined with panoramic ultrasound imaging enables detection of acute, localized variations in cross-sectional area and muscle thickness between different heads of the pectoralis major following resistance exercise.

Source: Non-uniform excitation of pectoralis major induced by changes in bench press inclination leads to uneven variations in the cross-sectional area measured by panoramic ultrasonography

What the research says

Supports is higher

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

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.

Description
1 study reviewed
In plain English

Scientists can use two tools together - one that measures muscle electrical activity and another that takes wide ultrasound pictures - to see how specific parts of the chest muscle change right after working out.

What the research says

1 study

  1. Study: Non-uniform excitation of pectoralis major induced by changes in bench press inclination leads to uneven variations in the cross-sectional area measured by panoramic ultrasonography

    The study used the exact method mentioned in the claim (surface EMG plus panoramic ultrasound) and showed it works - they could detect different amounts of swelling and thickening in the upper vs lower parts of the chest muscle after different types of bench press exercises.
