Abstract：    The purpose of this study was to determine the effect of modified Tai Chi and Qigong (m-TC/Q) program intervention on functional fitness in elderly. A pretest-posttest quasi-experiment design method was adopted, and two communities of older adults were recruited to accept either the m-TC/Q or another competitive program. The results showed that the m-TC/Q program improved five items of the Senior Fitness Test (SFT) with an exception for the Back Scratch Test. A further analysis of progress scores revealed that the m-TC/Q was better than the Western style exercise program on the lower extremity flexibility. We conclude that the m-TC/Q exercise program is proven to be an effective intervention for elderly to improve their functional fitness. (Full text)
