The study investigated muscle hypertrophy using ultrasound imaging, specifically measuring the thickness of the muscle at different points.

MRI imaging was also used as it's considered more accurate and reliable for hypertrophy studies.

Based on successful tests with various trained athletes, a professional orthosis prototype was developed for calf muscle stretching 

The orthosis was used to test muscle strength, flexibility, and thickness. Different stretching intensities and durations were applied using the orthosis in the study.
