摘要

Purpose: The purpose of this study was to investigate the relationship between knee extensor muscle strength (KE) and the 30-sec chair stand test (30-sec CST) of the elderly with different general health status and living in different communities in Northern Taiwan. Methods: In this cross-sectional study, we recruited 202 older adults. Among them, ninety subjects (mean age=78.31±5.25) were from a well-supervised and serviced retirement community, where a rigorous health screen for each older adult was carried out before they can move in, and 112 subjects (mean age=74.57±6.22) were from an internal medicine clinic in the CGMH, Linkou, Taiwan. The 30-sec CST and the knee extensor muscle strength measured by the MicroFET3 handheld dynamometer were tested for all of the older adults. All of the older adults were grouped into 2 groups according to chronic disease status for statistical analyses. Descriptive statistics of variables of the two groups were provided and the differences between groups were tested by the Mann-Whitney test. The relationship of the 30-sec CST and the knee extensor muscle strength was analyzed by partial correlation coefficience adjusted by age, weight and regular exercise status. Results: The results showed average body weight of elderly without chronic disease was significantly lower than that with chronic disease (58.48±8.99 vs. 61.86±10.51, p＜.05). Female without chronic disease significantly outperformed those with chronic disease in the 30-sec CST(12.71±4.78 vs. 11.38±4.29, p＜.05). There were significantly positive correlation of the 30-sec CST and the KE in both sex of the elderly with chronic disease(male r=.49; female r=.33, p＜.001) and the female without chronic disease (r=.32, p＜.05), but not in the male without chronic disease (r=.25, p=.14). Conclusion: The 30-sec CST was widely used to represent lower extremities muscle strength and endurance in the elderly fitness test. However, the 30-sec CST correlated well with KE only in the elderly with average health status, but not in those in the upper end of health status. Using the 30-sec CST to represent muscle strength in the fitness test for the healthier elderly should be with caution. (FJPT 2008;33(5):287-293)
