A limiting factor in evaluating the functional status of older people is the lack of appropriate measurement tools for assessing functional mobility, muscle strength, aerobic endurance, agility, and flexibility. In this study, the reliability and validity of the seven-item Fullerton Functional Fitness Test (FFT) battery, designed for use with community-dwelling older adults, was examined. The test items were as follows: floor sit-and-reach, back scratch, 8-ft up-and-go, arm curl, 30-s chair stand. 2-min step, and 9-min walk. Seventy-nine participants (42 physically active, 37 sedentary) completed the FFT battery three times within a 2-week period. The test-retest reliability intraclass correlation coefficients were high. Construct validity analysis revealed that five of the seven FFT items discriminated between the physically active and sedentary groups. In conclusion, most of the evidence from the stability reliability and discriminant validity analyses supports the view that the Fullerton FFT battery is a reliable and valid test of functional fitness.
