Abstract

The aim of this randomized controlled trial was to determine the effects of 8-week exercise-intervention on cognition and related serum biochemical markers in nonagenarians. We also studied the effects of a 4-week training cessation (‘detraining’) period on our study variables. Participants were randomly allocated to a standard-care (control) or intervention (exercise) group [n=20 (16 women)/group]. The intervention focused on supervised, light-to-moderate-intensity aerobic and resistance exercises (mainly leg press), and included 3 weekly sessions. Cognitive status was determined by the mini-mental state examination and geriatric depression scale. We analysed proteins with reported relation with mechanisms behind cognition changes such as serum levels of angiotensin converting enzyme, amyloid-precursor protein, epidermal growth factor, brain-derived neural factor and tumor necrosis factor. No significant change (P>0.05) in any of the variables studied was found following the exercise intervention compared with the standard-care group. Similarly, no significant changes (P>0.05) were observed following the detraining period compared with the standard-care group. Overall changes after the exercise intervention in serum biomarkers were not associated with changes in functional capacity and cognitive measures. An 8-week exercise intervention focusing on resistance exercises neither benefits cognitive function nor affects the levels of the serum proteins analysed in nonagenarians.
