ABSTRACT

[Purpose] Evaluating the aging of senior and providing optimal sevices are important things for successful aging. This study identified functional fitness related with heath of aged 65 years or older and developed an age scale (longevity fitness age) for assessing their aging. [Methods] Participants were 458 older people (166 male, 292 female). They were divided into healthy group and disease group. Healthy group was used for the development of the longevity age equation and disease group was for investigating the validity of the equation. Participants completed 13 function fitness variables. The first principal component obtained from a principal component analysis was used to compute the equation. All variables except for grip strength and carrying beans were correlated with chronological aged. Grip strength and variables related lower functional fitness had differences between healthy group and disease group. Finally, 4 variables were selected for the equation. [Results] It was the following: longevity fitness age=0.942*X1+2, 185*X2+0.673*X3+0.051*X4+0.588*chronological age+58.401, where X1=standing up from a supine position, sec (s), X2=maximum walking (s), X3=standing up and sitting down a chair (s), X4=one leg balance with eyes open (s). The longevity fitness age of healthy group do not have a difference compared to their chronological age but disease group had a difference significantly. Age difference (chronological age-longevity fitness age) of sedentary group in disease group was significantly bigger than its active group. Longevity fitness age could assess an aging of senior. [Conclusion] We suggest that it can use as the tool for early detecting senior who need the health care service.
