All data represent mean ± standard deviation. Exp.—experimental group; Con.—control group; Pre—pretest; Post—posttest; M—mean; SD—standard deviation; G—groups; T—time; G × T— groups × time. * p < 0.05 were analyzed by two-way repeated measures ANOVA. ASM—appendicular skeletal muscle mass; SMI—skeletal muscle index.
