Daily physical activity affects exercise tolerance in patients with idiopathic pulmonary fibrosis

muscle mass, percentage body fat) were evaluated before the intervention and at three and six months during the exercise program. Results: The subjects exercised for a mean of 3.0± 1.3 times per week, including the home exercises. At three months, the body weights (57.4± 11.0 kg to 56.8± 10.9 kg, pu003c 0.05), fat mass (18.7± 6.9 kg to 17.9± 6.9 kg, pu003c 0.05) and %Fat values (32.2± 7.6% to 31.0± 7.9%, pu003c 0.05) had significantly decreased. Following the completion of the sixmonth program, the CAVI values also significantly decreased (8.45± 0.94 to 8.20± 0.87, pu003c 0.05), whereas the muscle mass significantly increased (36.5± 7.3 kg to 37.1± 7.1 kg, pu003c 0.05). Conclusion(s): These results suggest that performing Tai chiYuttari-exercises approximately three times aweek for six months results in improvements in arterial stiffness in elderly people, which may have beneficial effects in preventing arteriosclerotic diseases. Implications: The current Tai chi Yuttari-exercise based intervention program for elderly subjects was useful for preventing lifestyle-related diseases, such as cardiovascular and cerebrovascular disease.
