Fit With Z: Effects of Exercise on Adult Cognition
The positive effect of exercise on cognition of older adults appears to be more than that of younger adults. This could be due to older adults having more to gain as age-related declines become more prevalent. The meta-analysis indicated that the largest fitness-induced benefit occurred for executive-control processes. The same analysis found that exercise programs involving both aerobic exercise and strength training produced better results on cognitive abilities than either one alone. A study conducted by Etnier et al. (1997) illustrated that maintaining a high fitness level in older adulthood helps with performance on fluid intelligence tasks.
