Each year there are increasing numbers of older adults within the United States. By the year 2030, 1 out of every 5 Americans will be 65 or over. By the age of 80, 1 out of every 2 older adults will be affected by a cognitive impairment. A growing body of literature supports the positive impact of cardiovascular/aerobic physical activity on cognition; however, little is known about mind–body physical activities and the impact on cognition of older adults. With the rising costs of health care, it is vital to explore physical activities that are physically feasible, such as Tai Chi, for older adults that can preserve or restore cognitive function. A quantitative, preexperimental, static group comparison design was utilized to assess the impact of Tai Chi on the cognitive abilities of older adults. A significant association between the practice of Tai Chi and global cognition, verbal memory, and process timing was found. Older adults who participated in Tai Chi not only performed better on testing but were faster in generating the correct answers.
