Δ Trail B - Trail A (sec) ^†	8.64 (32.15)	7.30 (30.36)	10.96 (36.92)	8.97 (33.06)
Δ Digit Forward - Digit Backward ^†	-0.64 (2.70)	0.06 (2.54)	-0.47 (2.24)	-0.34 (2.50)
Δ Gait Speed (m/sec) **	0.22 (0.18)	0.19 (0.19)	0.24 (0.16)	0.22 (0.18)
Δ ABC Scale Score (%) **	2.83 (9.91)	2.26 (10.27)	-1.37 (10.60)	1.19 (10.37)

* BAT = Balance and Tone; 1× RT = once-weekly resistance training; 2 × RT = twice-weekly resistance training; Stroop CW = Stroop colour-words condition; Stroop C = Stroop coloured-X's condition; m/sec = meters per second; ABC = Activities-Specific Balance Confidence.
** Mean change = final value minus baseline value. Positive change indicates improvement.
^† Mean change = baseline value minus final value. Positive change indicates improvement.
