During the first year of follow-up, 20 of the 213 participants assigned to the physical activity intervention and 24 of the 211 assigned to the successful aging intervention were unable to complete the 400 meter walk at the 6- and/or 12-month assessment. Of participants who were successful at completing a 4 meter walk at baseline, 11 of the 206 who were assigned to the physical activity intervention and 13 of the 202 assigned to successful aging were unable to complete the 4 meter walk at the 6- and/or 12-month examination.
