  • Purpose: The purpose of this study was to investigate the effects of a 12-week Tai Chi on the bone mineral density and bone metabolic markers in postmenopausal women Methods: Data were collected from March to July, 2009. Fifty postmenopausal women were recruited for the study. Twenty two women were allocated to experimental group, and 28 to control group. The experimental group underwent Tai Chi exercise twice a week for twelve weeks. The control group was only notified with results of bone mineral density and bone metabolic markers. Bone mineral density was measured by using of DTX-200 (Osteometer MediTech, Hawthorne, CA, USA) at distal radius site and bone metabolic markers were measured by radioimmunoassay method. Collected data were analyzed by t-test, $X^2$-test, and Mann-Whitney test. Results: After 12 weeks of treatment, the Tai Chi group showed a significant difference in bone mineral density compared to control group but no significant effect on osteocalcin and deoxypyridinoline level. Conclusion: Our results suggest that 12 weeks of Tai chi may delay bone loss in postmenopausal women.

  • Purpose: The purpose of this study was to compare the effects of Tai-Chi exercise (TCE) and resistance exercise (RE) when used as part of a community-based exercise program on improvement of physical function in elderly women with knee arthritis. Methods: Forty-seven women with knee arthritis participated in this study. They were assigned to one of two groups: the TCE group (n=22) or the RE group (n=25). Tai-Chi exercise and resistance exercise sessions were held for 1 hour per session, twice per week, for 8 consecutive weeks. At pre-treatment and post-treatment, subjects were tested using the following measurements: one-legged stand test (sec), a functional reach test (cm), a test of the strength of the knee extensor and flexor muscles, determination of the pathway of center of foot pressure and vertical ground reaction force for stance phase at pre and post treatment time points. An independent t-test and a ${\chi}^2$ were used to determine the significance of differences between group means using SPSS 12.0. Results: After 8 weeks of participation in the exercise programs, there were significant improvements for both groups in joint pain, difficulty of performing activity, muscle strength of knee extensor and flexor. Also, vertical ground reaction force increased at the loading response phase for both groups. The RE group was significantly different from TC group on the eyes-closed one-legged stand test (sec). Conclusion: Tai-Chi exercise and resistance exercise programs improve physical functioning and reduce pain and locomotion difficulties.

  • This study compared the unweighted sample design, frequency weighted sample design and complex sample design to using 2009 Korea National Health and Nutrition Examination Survey in an effort to identify whether or not there is any difference in potential risk factors. Pearson chi-square test and Rao-scott chi-square test were applied to the analytic methods. As a result of analyses, all the variables were overestimated as significant risk factors in case of the unweighted sample design to which only the frequency weights were applied. In addition, there were differences in the confidence levels and results from the simple random sampling analysis and complex sample design to which no weight was applied. It is necessary to carry out the complex sample design rather than the analysis to which the frequency weights are applied, in order to ensure the findings to represent the whole population when our national statistics data is used.

  • PURPOSE: To investigate the effects of the underwater Ai-Chi exercise on the joint range of motion, balance and posture. METHODS: Thirty-six college students (30 men, 6 women) were divided into a 'low physical activity' groups (Group I). and an 'appropriate physical activity' groups (Group II). The Ai-Chi underwater exercise was conducted three times a week for two weeks for both groups. A goniometer was used to measure the range of motion of the hip joint, and Y-Balance and the posture screen mobile were used to measure the stability of the lower extremities. RESULTS: An evaluation of the range of motion of the hip joint before and after the Ai-Chi exercise showed significant results in the low physical activity group. However, the flexural range showed a significant increase after exercise, but not significant result. In the comparison of the mean increase between groups, only the right hip joint showed a significant difference in both groups. Also, in the comparison of the Y balance test and posture screen test before and after exercise, both groups showed significant. CONCLUSION: The Ai-Chi underwater exercise helped improve the range of motion of the hip joint and the ability to balance. Also It helped improve posture alignment. In addition, although the increase in all physical activity groups lower than the appropriate physical activity groups was greater in all figures, the increase in the number of samples, the extension of the experimental period, and various variables could be obtained.

  • Purpose: This study was to determine whether the Sun-style 24 forms of Tai Chi exercise improve pain, stiffness, disability, knee joint motion, mobility, balance or falling. Method: Forty-six community-dwelling elderly subjects (mean age, $75.46{\pm}6.28$) voluntarily participated in an intervention group of either 24 forms of Sun-style T ai Chi for 60 min, 2 times per week for 12 weeks or a control group. A non-equivalent pretest-posttest design was used. Independent t-test and ANCOVA were used to examine group differences by using SPSS12.0. Result: The experimental group had significantly less pain (F=7.60, p=.008) and stiffness (t=-3.19, p=.003) than the control group. Also there were significant improvements in knee joint motion on the right knee (t=2.44, p=.019), left knee (t=2.30, p=.026), rising time (F=8.03, p=.07), balance on the left single leg test (t=2.20, p=.033), and fear of falling (t=-2.33, p=.024) in the Tai Chi exercise group. No significant group differences were found in disability and falls efficacy. Conclusion: The Sun-style 24 forms Tai Chi exercise is effective in decreasing pain, stiffness, fear of falling and it improves balance, rising time, and knee joint motion. We suggest a continuing long term intervention to decrease disability and increase efficacy concerning falls.
