This article describes a nationwide study conducted to develop normative pe
rformance data for community-residing older adults. The physical parameters
assessed are strength, aerobic endurance, flexibility, and agility/balance
. Body mass index was also assessed as an estimate of body composition. The
sample comprised 7,183 participants from 267 sires in 21 states. Summary d
ata (M, SD, and percentiles) are reported separately for men and women in 5
-year age groups. Results reveal a pattern of decline across most age group
s on all variables. ANOVA and post hoc comparisons indicated a significant
main effect for age on all variables and that most 5-year age-group decline
s were significant (p < .007). ANOVAs also revealed a significant main effe
ct for gender on all test items (p < .0001): Men scored better on strength,
aerobic endurance, and agility/balance; women scored better on flexibility
. The data provide information about normal variations within and usual rat
es of change across age groups, and they provide a database for subsequent
evaluation of individual and group performance.
