The Claim
Muscle thickness measured by ultrasound at 50%, 60%, and 70% of the acromion-olecranon distance demonstrates excellent intra-rater reliability (ICC = 0.96, 95% CI: 0.93–0.99) in recreationally trained women, supporting its validity as a proxy measure for upper arm muscle hypertrophy in resistance training studies.
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.
Ultrasound can reliably measure arm muscle size in active women, and the same person can get consistent results when repeating the measurement—making it a trustworthy way to track muscle growth from workouts.
See the scientific wording
Muscle thickness measured via ultrasound at 50%, 60%, and 70% of the acromion-olecranon distance is a reliable method for assessing upper arm hypertrophy in recreationally trained women, with excellent intra-rater reliability (ICC = 0.96, 95% CI: 0.93–0.99), supporting its use as a valid proxy for muscle size changes in resistance training studies.
What the research says
1 studyThe study used the same ultrasound method described in the claim and found it could detect muscle growth, which suggests it's a useful and reliable way to measure changes in arm muscle size.
