N2 - Background. The purpose of this study was to determine the relationship between peak aerobic power (VO2peak) and performance on a modified Physical Performance Test (modified PPT) in older women. Methods. One hundred one women aged 75 years and older seeking enrollment in randomized, controlled trials of exercise and/or hormone replacement therapy were recruited from the community-at-large and from congregate living sites. Measures obtained included VD2Peakia modified PPT, and self-reports about performance of activities of daily living. Results. Simple regression analysis demonstrated that VO2peak was associated with total PPT score (r =.53, p <.001 ), gait speed (r =.44, p <.001 ), time to arise from a chair five times (r =.43, p = <001), and time to climb one flight of stairs (r =.36, p =.007). Multiple regression analysis revealed that the relationships between VO2peak and total modified PPT score, gait speed, chair rise time, and time to climb one flight of stairs were independent of age. Conclusions. Peak aerobic power is a significant independent predictor of performance on a standardized test of physical function in older women and is an important component of physical frailty in this population.
