Median slopes of key variables are as follows: Δpeak torque, −3.31 Nm/year; ΔALM, −0.14 kg/year; Δfat, 0.13 kg/year. Change in gait speed is in m/s/year. In peak torque (PT) and appendicular lean mass (ALM), ‘greater decline’ is defined as larger than median value, while ‘less decline’ means smaller than median value. In fat, ‘increase’ is defined as larger than median value because median value of Δfat is 0.13 kg/year, whereas ‘decrease’ means smaller than median value.
