Measuring physical performance in highly active older adults: associations with age and gender?

Abstract

Higher age is associated with reduced physical capability in the general population. The role of age and gender for physical performance in older adults who exercises regularly is, however, not clear, and there is also a lack of recommendations for outcomes to address physical performance for this population. To explore the associations between physical performance, age and gender, and to examine the suitability and feasibility of clinical field tests for physical performance in active older adults. In this cross-sectional study we included 105 persons, 70-90years of age, who had exercised regularly for ≥ 12months. The field tests were Short Physical Performance Battery (SPPB), Timed Up and Go and gait speed for mobility; One-leg standing (OLS) test and Mini-BESTest for balance; Stair test for endurance, 30s sit-to-stand, and grip strength for muscle strength. We found associations between age and physical performance, and the associations were slightly stronger for women. Men performed better on tests of muscle strength, balance and endurance, while no gender differences were found in mobility. Grip strength was not associated with mobility tests for men. All tests were feasible, while SPPB and OLS had ceiling and floor effects that limit their suitability in this population. Both age and gender were associated with physical performance. We recommend using the gait speed, Mini-BESTest, 30s sit-to-stand, grip strength and stair tests to assess physical performance in physically active older adults.
