This feasibility study compared the effects of Tai Chi (TC) and resistance training (RT) on bone metabolism in the elderly. Twenty eight sedentary, elder adults, were randomized into either TC (n = 14, 78.8 +/-1.3 years) or RT (n = 14, 79.4 +/-2.2 years) to participate in 40 min of exercise per session, 3 sessions/week for 24 weeks. The outcome measures assessed were the concentrations of serum bone-specific alkaline phosphatase (BAP), pyridinoline (PYD), parathyroid hormone (PTH) and calcium, and urinary calcium. The TC group had a higher compliance rate than the RT group. After 6 weeks, (i) both TC and RT resulted in higher level of serum BAP relative to the baseline and the TC group exhibited a greater increase in serum BAP than the RT group; (ii) there was an increase of serum PYD in the RT group only, not in the TC group; and (iii) the BAP/PYD ratio was higher than baseline only in the TC group, and the increase of the ratio in the TC group was greater than that in the RT group. After 12 weeks, the increase in serum PTH in the TC group was higher than the RT group. After 24 weeks, there was a reduction of the urinary calcium level in the TC group relative to the baseline. In conclusion, these findings support that TC is beneficial for increasing bone formation in elderly, and long-term application is needed to substantiate the effect of TC as an alternative exercise in promotion of bone health.

Our previous study has demonstrated that 6 weeks of Tai Chi exercise significantly improves knee pain and stiffness in elderly with knee osteoarthritis. This study also examine the effects of Tai Chi exercise on gait kinematics, physical function, pain, and pain self-efficacy in elderly with knee osteoarthritis. In this prospective, pretest-posttest clinical trial, 40 men and women (64.4 ± 8.3 years) diagnosed with knee osteoarthritis participated in 6 weeks of instructed Tai Chi training, 1 hour/session, 2 sessions/week. The following measures were taken at baseline and the conclusion of the intervention: (a) gait kinematics including stride length, stride frequency, and gait speed quantified using video analysis, (b) physical function, (c) knee pain, and (d) pain self-efficacy. Data were analyzed using repeated MANCOVA, MANOVA, ANOVA and Wilcoxon tests. After 6 weeks of Tai Chi exercise, stride length (p = 0.023; 1.17 ± 0.17 vs. 1.20 ± 0.14 m), stride frequency (p = 0.014; 0.91 ± 0.08 vs. 0.93 ± 0.08 strides/s), and consequently gait speed (p < 0.025; 1.06 ± 0.19 vs. 1.12 ± 0.15 m/s) increased in the participants. Physical function was significantly improved (p < 0.001) and knee pain was significantly decreased (p = 0.002), while no change was observed in pain self-efficacy. In conclusion, these findings support that Tai Chi is beneficial for gait kinematics in elderly with knee osteoarthritis, and a longer term application is needed to substantiate the effect of Tai Chi as an alternative exercise in management of knee osteoarthritis.

Mind-body exercise, a form of physical exercise originating in the East with increasing popularity in the West, has a unique characteristic that requires conscious control of each body movement and concurrently maintaining a peaceful and relaxed state of mind during practice. With the ultimate goal of training both the body and the mind, there have been empirical findings supporting the positive effects of mind-body exercises on improving physical health condition (e.g., pulmonary function) as well as cognitive functions (e.g., learning and memory). This chapter will introduce a form of Chinese Chan-based mind-body exercise, namely Shaolin mind-body exercise or Chanwu, which was developed upon the traditional Shaolin Healing Approach. A brief description on some movements of Shaolin mind-body exercise will also be provided. Treatment outcomes based on both clinical observations and cumulative empirical evidence are so far encouraging. Specifically, intervention with the component of Shaolin mind-body exercise has been found to be able to foster a relaxed and attentive mind state of normal adults, significantly improve depressive mood and enhance bowel function and neurophysiological activity of both community-dwelling adults and patients with major depressive disorder. Some clinical cases with severe cognitive impairment have also been assessed to show significant enhancement in their attention, memory, language and executive functions. These positive findings have suggested potential clinical applicability of the Shaolin mind-body exercise as a possible neuropsychological intervention for improving cognitive function and psychological status of patients with various brain disorders or psychiatric illnesses.
