| Sumario: | Masaki Nakagaichi,1 Yuya Anan,2 Yuto Hikiji,3 Sou Uratani4 1Sports and Life Sciences, National Institute of Fitness and Sports in KANOYA, Kanoya, Japan; 2Department of Nutritional Health, Kwassui Women’s University, Nagasaki, Japan; 3Department of Rehabilitation, Nagasaki Yuai Hospital, Kyoseikai Medical Corporation, Nagasaki, Japan; 4Nonprofit Organization Nagasaki Wellness Sports Research Center, Nagasaki, Japan Objectives: The purpose of this study was to identify a method for assessing physical fitness age that is easy to use with both frail and healthy elderly women and to examine its validity.Methods: Principal component analysis was used to develop a formula of physical fitness age from four motor function variables. The subjects comprised 688 (75.7±6.0 years) elderly women, in order to develop a physical fitness scale. The formula for calculating physical fitness age was expressed as physical fitness age =-0.419× grip strength -0.096× balancing on one leg with eyes open -0.737×30 s chair stand +0.503× figure-of-8 walking test +0.47× chronological age +52.68.Results: Measures obtained from subjects in the frail elderly (n=11, 73.0±2.3 years) and exercise (n=10, 70.8±3.1 years) groups were used to examine the validity of the assessment. The mean physical fitness age of the frail elderly group (79.0±3.7 years) was significantly higher than its mean chronological age (73.0±2.3 years, p<0.05). The mean physical fitness age of the exercise group (65.6±3.1 years) was significantly lower than the chronological age (70.8±3.1 years, p<0.05).Conclusion: These findings confirm that physical fitness age scores are applicable to frail and healthy elderly women. Physical fitness age is a valid measure of motor function in elderly women. Keywords: physical fitness age, motor function, frail and health elderly women, aging, care prevention |
