Five reviewers independently identified the studies that met the criteria for the review and discrepancies were resolved by consensus among all authors.RESULTS:Fifty-one studies were included in this review with 5 from the period between 1989-1999, 11 from 2000-2006, and 35 from 2007-2013. The evolution of study designs changed from aerobic only exercise training interventions(1989-1999), to a combination of aerobic and resistance training(2000-2006), to studies including an arm of resistance training or examining the effects of resistance training as the main mode of exercise(2007-2013). Overall, the benefits of exercise showed improvements in cardiorespiratory function, body composition, strength, and patient reported outcomes including fatigue, depression, and quality of life.CONCLUSION:Exercise training appears to be safe for most breast cancer patients and improvements in physiological, psychological, and functional parameters can be attained with regular participation in moderate intensity exercise.展开更多

The subjects were females with an average age of 74 years who had been continuously practicing Tai Chi Yuttari-exercise for at least six months. The heart rate and blood pressure were measured before and after the subjects performed four different versions of Tai Chi Yuttari-exercise. The perceived exertion was evaluated using the Borg scale. The respiratory rate, oxygen uptake and respiratory quotient (RQ) were measured using an expired gas analyzer. The results showed an increase in heart rate during exercise, but confirmed that the rise in HR was below the safety limit. The blood pressure tended to be low post-exercise. Regarding perceived exertion, the maximum heart-lungs Borg scale response was 9 (very light). A slight increase in the respiratory rate was observed while exercising, but no abnormal breathing patterns were observed. The average metabolic equivalents (METs) of the exercise ranged from 1.34 to 1.87, and the average RQ ranged from 0.82 to 0.90. The circulatory-respiratory dynamics observed in this study verified that elderly females with an average age of 70 years could safely perform the Tai Chi Yuttari-exercise. This study helped obtain basic data for expanding the indications for this exercise.展开更多
