This study found a correlation between older adults' lifetime physical activity and activity levels, emphasizing the importance of lifelong engagement in physical activity.
This study investigates methods of data gathering and management, along with the relationship of lifespan and older adults' activity. Community-dwelling older adults (n = 47, 81.7 +/- 3.6 years) completed the Lifetime Leisure Physical Activity Questionnaire. Current activity was assessed by use of accelerometers. The data were converted to the metabolic equivalent of task hours. Correlations between the main outcomes (metabolic equivalent of task/hour, Lifetime Leisure Physical Activity Questionnaire), as well as individual estimation errors for data adjustments, were computed. The accelerometer and Lifetime Leisure Physical Activity Questionnaire data for the last 12 months' activity were associated (r=.31, p=.033). The average overestimation in the self-reported data was 176%. The adapted data on lifetime physical activity reveals correlations between older adults' activity and the activity levels of three 15-year episodes (r=.354; r=.336; r=.323; each p <.05), as well as compliance with guidelines throughout life (Hotelling's T2 = 45-164; p <= .002). Our findings indicate a relationship between lifetime and older adults' activity and provide further support for lifelong engagement in physical activity.
