Age score for assessing motor function in Chinese community-dwelling older women

Is Subjective Age Associated with Physical Fitness in Community-Dwelling Older Adults?

“…In the second phase, the physical fitness was reflected by assessing the muscle strength, balance, muscle endurance, usual gait speed, and cardiopulmonary endurance. Referring to previous studies [ 4 , 5 , 25 , 26 ], a series of test items including grip strength, balancing on one leg with eyes open, the 30 s chair stand test, 4 m habitual walk, and 6 min walk test were selected in our study. Before the test, all participants conducted a 5 min warm-up and were then familiarized with the different test items.…”

“…However, in the gerontology field, chronological age seems to be less important than it is projected to be, especially for the oldest adults. This is because even if persons have the same chronological age, their degree of aging and overall health may differ from person to person, affected by factors such as familial heredity, diseases, physical activity, and eating habits [ 3 , 4 , 5 ]. Thus, chronological age is not a perfect measure for assessing one’s degree of aging and overall health.…”

Effect of telling older adults their predictive physical fitness age on physical activity: A quasi‐experimental study

“…In order to obtain the predictive physical fitness age of each participant, four items including grip strength, balancing on one leg with eyes open, 30 s chair stand, and 6 min walk distance were measured. The four items were selected according to published formulas of physical fitness age that were developed based on Chinese older adults (Zhao et al., 2020, 2021). The predictive formula of physical fitness age is as follows: 115.516−0.652 × grip strength (kilograms)−0.142 × balancing on one leg with eyes open (seconds)−0.839 × 30 s chair stand (repetitions)−0.061 × 6 min walk distance (meters) + 0.541 × chronological age (years) for men, and 104.733–0.791 × grip strength (kilograms)–0.158 × balancing on one leg with eyes open (seconds)–0.648 × 30 s chair stand (repetitions)–0.049 × 6 min walk distance (meters) + 0.419 × chronological age (years) for women.…”

“…For instance, if one's physical fitness age is older than chronological age, it means that the person has low physical fitness, and vice versa. One study showed that physical fitness age might motivate older persons to promote or keep physical activity by participating in exercises and sports (Zhao et al., 2020). Another study also suggested that physical fitness age was not only as a way of making physical fitness data easier to understand especially for older adults, but also a possible incentive to increase physical activity (Latorre‐Rojas et al., 2019).…”
