It has been suggested that physical and cognitive functions are associated with health-related quality of life (HRQL). Previous work examining the relationship between physical ability and HRQL is equivocal, and information about cognitive function in relation to HRQL is largely restricted to people with cognitive impairments. We investigated the relationships of physical ability and cognitive performance to HRQL in 44 older adults (72-93 years). The results suggest significant relationships between the endurance item of the AAHPERD test and the physical mobility and pain components of HRQL and between AAHPERD agility scores and the physical mobility component of HRQL. Visual simple-reaction time and the backward digit-span memory test were found to be related to physical mobility. The subject-performed-tasks memory test was related to the social component of HRQL. These data support the use of the AAHPERD test for characterizing physical ability of older adults as it relates to HRQL and identify specific cognitive support measures that reflect the relationship between cognition and HRQL in older adults.
