Estimated Least Squares Means (Standard Errors) for SPPB From Repeated Measures ANCOVA^*

	Time of Assessment
	Baseline	6-Month FU	12-Month FU	36-Month FU
Successful aging	7.6	7.6 (0.3)	7.4 (0.3)	7.3 (0.3)
	n = 51	n = 49	n = 49	n = 38
Physical activity	7.6	8.8 (0.3)	8.3 (0.3)	8.3 (0.3)
	n = 55	n = 50	n = 53	n = 41
p values		.001	.023	.052

Notes: ANCOVA = analysis of covariance; FU = follow-up; SPPB = Short Physical Performance Battery.

^*Results are adjusted for gender and baseline walking speed. The p value for the test of equality of average group effects across all FU visits is .006.
