This report provides reliability and prevalence estimates by sex, age, and race/ethnicity of an observed physical performance examination (PPE) assessing mobility and balance.The Third National Health and Nutrition Examination Survey (NHANES III) 1988-1994.A cross-sectional nationally representative survey.All persons aged 60 and older (n = 5,403) who performed the PPE either in the mobile examination center (MEC) or in the home during NHANES III (conducted 1988-1994).The PPE included timed chair stand, full tandem stand, and timed 8-foot walk.Timed chair stand and 8-foot timed walk were reliable measurements (Intraclass Correlations > 0.5). Women were significantly slower (P < .001) than men for both timed chair stands and timed walk. Non-Hispanic white men and women did the maneuvers in significantly less time than non-Hispanic black men and women and Mexican Americans women (P < .001).Lower extremity functions measured by timed chair stand and walk are reliable. Women at every age group were more physically limited than men.
