Arms	2.4 ± 0.3	1.9 ± 0.2	1.6 ± 0.2	1.3 ± 0.1	t(144) = −16.9, P < 0.0001	t(302) = −21.8, P < 0.0001	t(141) = −12.6, P < 0.0001	t(286) = −13.2, P < 0.0001
Extremities	8.5 ± 0.9	7.8 ± 0.7	6.6 ± 0.7	6.0 ± 0.5	t(151) = −8.6, P < 0.0001	t(310) = −13.0, P < 0.0001	t(150) = −7.2, P < 0.0001	t(303) = −8.8, P < 0.0001

MMIs, muscle mass indexes, were expressed as mean ± SD
