| Research Abstract |
The purpose of the present investigation was to examine the optimal levels and timings of daily physical activity to maintain immunological function in older individuals. All subjects were independently living. In order to assess the number of steps and the time for moderate to vigorous intensity physical activity, all subjects wore a pedometer with one-axial accelerometer (Lifecorder, Kenz, Nagoya) continuously for 1 year. We assessed the salivary secretory immunoglobulin A and the neutrophil phagocytosis function at the resting condition. As results, the neutrophil phagocytosis function significantly associated with the number of step counts (p<0.05). The salivary secretory immunoglobulin A significantly associated with both the number of step counts and the time for moderate to vigorous intensity physical activity (p<0.05). These results indicate that the habitual physical activity have important role to maintain the immunological functions in older individuals.
