摘要

The long-term practice of Tai Chi can attenuate the age decline in physical function for the elderly individuals. However, whether short-term intensive Tai Chi training can significantly improve the lower-extremity strength and balance performance in the elderly is not clear. Purpose: To investigate the effects of 8-wk intense 24-forms Tai Chi training on lower-extremity isokinetic strength (ISOK) and balance performance in older women. Additionally, how long the intensive Tai Chi training could significantly improve ISOK and balance also been investigated. Methods: Thirty community-residing women (age 66.1± 4.0 yr) were recruited as subjects and randomly assigned to Tai Chi group (TCG) and control group (CG). TCG had trained for 5 d/wk, 60 min/session, with intensity of 55-65% maximal heart rate, while the CG received no training. A more dimension Fullerton Advanced Balance scale (FAB) tests and 8 ISOK were administered on a Cybex6000 isokinetic dynamometer before training, 4- and 8-wk after training of all subjects. The collected data were analyzed by mixed design two-way ANOVA. Results: 1) the sum torque of ISOK, strength of the knee extensor and hip adductor of TCG were significantly improved (p＜.05) after 8-wk training. 2) the total scores of 10 FAB items of TCG were significantly improved after 4- and 8-wk intensive Tai Chi training (p＜.05), and 6 items of FAB, including reaching forward to retrieve an object, turning in a full circle to right and left, tandem walk, standing on one leg, walk with head turns and reactive postural control were also significantly improved after training (p＜.05). Conclusion: Eight-week intensive Tai Chi training can both significantly improve multiple dimensions of balance performances and the lower extremity strength of older women.
