Age score for assessing motor function in Chinese older men

Abstract

Background and objective: Motor performance plays an important role in daily activities for older adults. The purpose of the study was to construct a method for measuring physical fitness age that can be used to assess motor performance in elderly men and to verify its validity. Methods: Four items of physical fitness including grip strength, balancing on one leg with eyes open, 30 s chair stand test and 6 min walk test were selected and measured in a random order. Principal component analysis was employed to build physical fitness age based on motor performance variables from 94 elderly men with a mean age of 71.20 ± 5.05 years. Physical fitness age = 115.516-0.652 × grip strength - 0.142 × balancing on one leg with eyes open - 0.839 × 30 s chair stand - 0.061 × 6 min walk distance + 0.541 × chronological age. Results: Validation test from 13 men with exercise habit and 12 men without exercise habit showed that the physical fitness age in the exercised adults was significantly lower than its chronological age (63.91 ± 5.40 vs. 70.92 ± 4.17, P < 0.001), while no significant difference was observed between physical fitness age and chronological age in the elderly without exercise habits (71.23 ± 7.49 vs. 70.83 ± 5.19, P = 0.646). Conclusion: Physical fitness age is a valid indicator to evaluate and monitor motor performance. Participation in physical exercise may lower the physical fitness age by improving motor performance.

Effect of smoking status on spirometric lung age in adult Chinese Men

“…It is known that exercise can improve respiratory function and quality of life (Chan et al, 2013;Papp et al, 2017;Yang et al, 2020;Zhao et al, 2021). Dogra et al (2019), for instance, demonstrated that 30 min of physical activities each day could lead to a rise in FEV 1 /FVC in both healthy adults and patients with obstructive lung diseases.…”

Relationship Between Physical Fitness, Anthropometric Measurement, and Bone Health in Adult Men

“…The total number of seconds was recorded from the time of eyes closing to the point where body balance was lost. Regarding the other physical fitness measurements, a full description for each measurement can be obtained from our previous studies (Takeshima et al, 2002;Zhao et al, 2017Zhao et al, , 2018Zhao et al, , 2020Zhao, Huang, Gu, et al, 2021).…”
