How shoulder angle affects muscle growth from weight training
Part of Bones, joints & muscles clinical trials.
This study looks at how the angle of your arm during shoulder exercises affects muscle growth in your back and forearm. If you are a healthy adult who already lifts weights regularly, you may qualify to help researchers understand how to make workouts more effective.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 19 and 30 years old.
- You must have been lifting weights (or doing other structured resistance training) for at least 2 hours each week for the past year.
- You must be in good general health, with no major heart, muscle, or metabolic conditions.
- You must not have any metal in your body that would make an MRI unsafe (like a pacemaker or metal screws).
- You must not be pregnant, a smoker, or on medications that affect muscle growth (like Metformin).
- You must not have had surgery or tattoos in the last 6 weeks.
