Abstract
BACKGROUND: We reported the effect of different motivations for physical activity on the amount of physical activity in older adults in need of institutionalized care using a wearable camera. Physical inactivity has been shown to promote worsening of pulse wave propagation velocity. However, the extent to which physical inactivity actually affects the pulse wave velocity, a health-related index, is unknown.
Objective: To clarify the effect of the difference in reasons for physically active behaviors on the worsening of pulse wave velocity on the amount of physical activity in residential care.
SUBJECTS AND METHODS: The subjects were eight patients with a history of cerebrovascular disease and three with a diagnosis of dementia living in a geriatric health care facility. There were 11 subjects, 2 males and 9 females, with an average age of 84 years and 90 years. The methods included behavioral recording and sequential interviewing of the subjects' reasons for their 24-hour activities using a stationary chest-mounted timed imaging device (recolo IR7; King Jim) and an IC recorder (ICD-PX440; SONY) to classify the motivation for each individual's physical activity and to determine the motivation for activities based on physiological demands, Divided by non-physiological demand-based activities and divided into two groups by the median of their total time and their effect on the worsening of pulse wave propagation velocity were evaluated by the unpaired t-test.
RESULTS: In the activity groups categorized by motivation for physical activity, the amount of physical activity based on the individual's non-physiological needs showed a significant mean difference in the amount of physical activity for the groups in which the total time of activity based on non-physiological needs was greater than 198.5 minutes and for the groups in which the total time of activity based on non-physiological needs was less than 198.5 minutes.
Conclusion: the amount of activity based on non-physiological needs had a significant effect on the amount of physical activity. The utilization of activities based on non-physiological needs is expected to be an effective method for the prevention of the syndrome of physical inactivity.
