Advantages of Phase Angle in Evaluating Physical Vitality Level

Proposal of Need Care Indicators for the Male Elderly People -An Approach Based on Phase Angle

“…In women, a marked decreasing trend in phase angle was shown at around the age of 80, revealing that the decrease is delayed by about 10 years compared with men. The interval of this delayed decrease, considering the shorter av-Health Educ Public Health 2022, 5:1 erage life expectancy in males, would truly seem to suggest the physical activity levels of elderly people proposed by Fujii et al [6]. Hence, it may be that after the age of 70 in men and the age of 80 in women are critical points for the rapid decline in physical activity level.…”

“…The establishment of a new health care indicator in elderly people is therefore thought to be necessary. In fact, Fujii et al [6] used phase angle in high school sports team members and a general control group, and showed that the height of the phase angle in the sports team members reflected their level of physical activity. This suggested that phase angle is useful in evaluating the level of physical activity.…”
