The Claim
Muscle thickness changes measured via panoramic ultrasound after resistance training reflect regional hypertrophy patterns rather than generalized swelling, as demonstrated by differential responses between proximal and distal regions of the elbow flexors following both acute and chronic training interventions.
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.
When muscle thickness is measured using ultrasound after strength training, differences in thickness between the upper and lower parts of the biceps indicate localized muscle growth, not just temporary fluid buildup.
See the scientific wording
Muscle thickness changes measured via panoramic ultrasound after resistance training reflect regional hypertrophy patterns rather than generalized swelling, as evidenced by differential responses between proximal and distal regions of the elbow flexors after both acute and chronic training.
When you lift weights, some parts of your arm muscle get stretched more than others, which causes those specific areas to grow thicker over time — not the whole muscle swelling up all at once.
What the research says
1 studyWhen people do dumbbell curls, their upper arm muscles get thicker near the shoulder but not near the elbow—this means the muscle is growing in specific spots, not just swelling up everywhere.
