Exercise is thought to benefit the brain both directly (reduces oxidative stress and inflammatory markers, and increases neurogenesis, angiogenesis, and synaptogenesis) and indirectly (reducing risk factors for cerebrovascular disease).
The lack of a significant association between exercise and neurocognition on certain domains in Hispanics might be explained by characteristics of our measure of exercise and/or the impact of other factors associated with Hispanic ethnicity (e.g., type of physical exercise, metabolic syndrome, genetic factors).
Future studies might further examine this association using measures of physical activity with strong psychometric properties in Hispanics and/or that are more objective (i.e., pedometers), as well as to investigate the potential role of other factors associated with Hispanic ethnicity on NC impairment. |
