Detailed Description:

Recently, considerable attention has been devoted to examining the beneficial relationship between cognition and aerobic exercise in older adults. Specifically, the effects are thought to involve higher order cognitive processes, such as working memory, switching between tasks, and inhibiting irrelevant information, all of which are thought to be sub- served, in part, by the frontal lobes (Colcombe et al., 2006). Importantly, these areas also are most susceptible to age-related decline (Raz, 2000) and are essential resources for language production (Kemper & Sumner, 2001; Murray & Lenz, 2001). However, despite promising cognitive improvement, changes in frontally-mediated executive language functions have been widely ignored. This is unfortunate considering impaired word retrieval compromises communicative effectiveness, leading to frustration, depression, and withdrawal. Perhaps more importantly, communication ineffectiveness, particularly in the elderly, leads to difficulties interacting with health care professionals leading to further health care burdens. Since cognition, and specifically word retrieval difficulties, usually remain untreated, it is important to find treatment strategies for minimizing these deficits. Therefore, the short-term goal and the purpose of this proposal is to examine the potential of aerobic exercise to improve executive language function in older adults.
