Muscle fibers composition and atrophy. ((a), (b), and (c)) In OA patients the rate of muscle loss was replaced mainly by adipose tissue (18.32%), whereas in OP muscle fasciculus atrophic muscle fibers were substituted by adipose (8.27%) and connective tissue (6.68%). ((d), (e), (f), (g), (h), and (i)) In OA patients we did not observed significant differences in fibers type atrophy, whereas In OP group we observed more than 50.00% of atrophic fibers with prevalence of type II fibers (21.10% type I and 39.20% type II).
