AIM: The aim of this paper was to examine the independent influence of cardiorespiratory fitness and sedentary behavior on chronic disease incidence and body composition in older adults.
METHODS: A sample of 292 community dwelling men and women (mean 69.3±8.1 years) underwent maximal treadmill testing and completed questionnaires relating to their leisure-time physical activity, sedentary time, and health.
RESULTS: The average V O2 of the sample was approximately 21ml.kg-1.min-1 with the average sedentary time being over 3 hours per day. Cardiorespiratory fitness was found to be a stronger predictor of number of chronic conditions and BMI than total physical activity and sedentary. Those with a higher cardiorespiratory fitness had fewer chronic conditions and a lower BMI. No such associations were seen for either total physical activity levels or sedentary time.
CONCLUSION: Cardiorespiratory fitness is a stronger predictor of health among older adults and further highlights the importance of promoting public health guidelines for cardiorespiratory fitness.
