  1. Deltoid muscle samples from lean, obese, young, and old patients were evaluated using our developed macro in Fiji-ImageJ. Values for CSA are means ± SEM. Atrophy and hypertrophy factors for all, type I, and II myofibers were computed based on a score for the fibers’ CSA size and normalized by the number of each fiber population within a section.
