a Maximal Strength was measured via 1 repetition maximum (1RM) testing in Newtons
b Relative Strength (kg/kg): (leg press strength (kg)/leg Fat Free Mass (kg)) measured by Dual X-Ray absorptiometry (DXA)
c Balance Index : (Sum of 12 sway measures + (180 - sum of 6 time measures) [49]
dStair Climb power (W): (Body Mass (kg) × vertical height of the staircase (m)) × 9.8/time (s)
e Gait velocity (average of 2 trials for habitual gait; maximal of 2 trials for maximal gait) measured over 2 m using an Ultratimer
