Data are presented as median (interquartile range), unless otherwise stated. Comparison of significant physical functioning measures expressed per kilogram appendicular skeletal muscle (ASM) across body composition phenotypes. V′O2peak: peak oxygen uptake; CET: cycle endurance time; ns: nonsignificant.
