In addition, based on neuroimaging data we propose potential mechanisms underlying this relationship and suggest several directions for further studies on the effects of Tai Ji Quan on cognition in older adults. A few recent studies have examined the relationship between Tai Ji Quan and cognitive performance in terms of attention, memory, and eye–hand coordination. With a cross-sectional design, Man et al.12 compared the DAPT solubility dmso performance of older adults who regularly participated in Tai
Ji Quan on attention and memory tests to those with and without regular PA habits. While the researchers observed better performance in the physically active older adults rather than those who were sedentary, the Tai Ji Quan group performed better in sustained and divided attention
as well as in everyday memory, encoding memory, and recall memory, compared click here with those in the regular PA group, which suggests that Tai Ji Quan provides additional beneficial effects on cognition. Another study reported a similar influence of Tai Ji Quan on cognition by examining the age effect. Hall et al.13 compared cognitive performance on a Rapid Index Finger-Pointing task among young adults, older adults with Tai Ji Quan experience, and older adults who were physically inactive. The results indicated that although older adults displayed worse performance in terms of reaction time, movement time, and response accuracy than younger adults, reflecting age-related cognitive decline, older adults with Tai Ji Quan experience displayed a shorter movement time
than their inactive counterparts, suggesting that Tai Ji Quan positively affects eye–hand coordination tasks that involve greater cognitive demand. The apparent beneficial effects of Tai Ji Quan on cognition that requires higher cognitive processing demonstrated by Hall et al.13 Fossariinae raises a question about whether Tai Ji Quan would benefit higher-order cognitive functioning, namely executive function. Indeed, meta-analysis has indicated that aerobic exercise not only benefits cognition in general (i.e., speed, spatial, and controlled aspects of cognition) but facilitates executive function to a greater degree,14 which suggests that the effects of exercise on cognition are disproportional. For example, using a pre–post-experimental design, Matthews and Williams15 determined that older adults who participated in a Tai Ji Quan intervention three times per week over 10 weeks improved executive function performance on the Trail Making Test B and Clock Drawing test, but not the Trail Making Test A or Digit Symbol test, which are indices of basic information processing tasks.
