The study used a competition-style trampoline, size in feet: 9'x15'. "Each phase of the sequence included a 2-min warm-up, followed by 5 min of jumping. The four heights, measured by the distance the subjects’ feet were elevated above the trampoline bed, were 18, 37, 75, and 100 cm.
The angular diameter, angular size, apparent diameter, or apparent size is an angular separation (in units of angle) describing how large a sphere or circle appears from a given point of view. In the vision sciences , it is called the visual angle , and in optics , it is the angular aperture (of a lens ).
