Stair climb SE (score)	53.7±9.3	46.8±5.7	45.8±6.0	39.7±6.2	26.6±7.4
400 m SE (score)	87.4^∗±8.2	76.1^∗±5.0	76.4^∗±5.3	74.5^∗±5.5	46.9±6.5
WOMAC pain scale	5.82^∗±1.3	7.06^∗±0.77	7.15^∗±0.82	7.44^∗±0.85	10.38±1.00

Values are the mean ± standard error; s = seconds; 400 m = 400-meter walk; SE = self-efficacy. ∗Denotes statistical difference from obese class III.
