Daytime physical activity patterns and physical fitness in institutionalized elderly women: an exploratory study.

This study investigated the relationship between daytime physical activity patterns and physical fitness in elderly women. The subjects comprised 19 elderly women who resided in a nursing home. Time spent lying, sitting, standing and walking and the number of steps taken during the daytime from 10:00 to 16:00 were measured to determine physical activity patterns. Physical fitness measures included muscle strength, balance, flexibility and physical performance. The elderly women spent 18.3% of their daytime walking, 7.31% in a standing position, 56.9% sitting and 17.4% lying down. Our results showed that the time spent in walking or standing positions was significantly associated with balance and physical performance such as walking speed, while the time spent in a sitting position was inversely associated with muscle strength, balance and physical performance. The results of this study suggest that the time the elderly spend on weight-bearing activities and in sedentary behavior are associated with physical fitness.
