Scientists map muscle activity during shoulder workouts
NCT ID NCT07297758
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This observational study at Hacettepe University will measure how the latissimus dorsi muscle activates during shoulder extension exercises using surface EMG. Thirty healthy adults aged 18-40 will perform resisted shoulder movements at different angles while muscle activity is recorded. The goal is to understand how exercise position affects muscle activation, which could inform rehabilitation or training programs.
