Effects of Tai Chi on Frailty in Elderly Adults

The Effects of Tai Chi on the Nonlinear Dynamics of Frailty in Elderly Adults

The aim of this study is determine the effects of Tai Chi exercise, as compared to an education-based control intervention, on cardiovascular and balance system function in older people at risk of developing frailty. We hypothesize that long-term Tai Chi training will improve specific nonlinear properties associated of cardiovascular and balance dynamics in this population.

Inclusion Criteria:

• Men and women over age 70 will be included if they are able to stand and walk unassisted, are free of any acute or unstable medical conditions, and are able to understand directions and participate in the protocol.

Exclusion Criteria:

• Potential subjects will be excluded 1) if they cannot stand and ambulate unassisted, 2) are experiencing any symptomatic cardiovascular or respiratory disease, or have 3) a myocardial infarction or stroke within 6 months, 4) painful arthritis, spinal stenosis, amputation, painful foot lesions, or neuropathy that limits balance and mobility, 5) systolic BP above 160 or diastolic BP above 100 mm Hg, 6) a cardiac pacemaker, 7) Parkinson's Disease or other neuromuscular disorder, 8) metastatic cancer or immunosuppressive therapy, or 9) have significant visual impairment.
