Is this trial a fit for you?

Likely a good fit

Ideal candidates are recreationally active adult males with good quality ultrasound images available from the original BFR protocol.

Probably not a fit

Patients with poor image quality or conditions that alter abdominal anatomy may not benefit from this reliability assessment.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study uses previously collected ultrasound images from healthy, recreationally active men who completed a low-load squat protocol with blood flow restriction. It retrospectively analyzes whether different raters produce similar thickness measurements of the rectus abdominis using a standardized protocol. The goal is to quantify inter-rater reliability for ultrasound-based muscle thickness assessment in this context. Only images meeting predefined quality criteria will be included, and measurements will follow a fixed procedure to minimize variability.

Why it matters

Potential benefit: If reliable, clinicians and researchers can trust ultrasound measurements of abdominal muscle thickness after BFR training across different assessors.

How similar studies have gone: Prior work shows mixed reliability for ultrasound muscle thickness measurements; this study adds data specific to rectus abdominis post-BFR training.
