Resumen: | Regular physical activity is protective against, and beneficial for, mild cognitive impairment (MCI), dementia, and Alzheimer´s disease. The mechanisms underlying these benefits remain unknown although it has been suggested that exercise-induced changes in the circadian pattern of cortisol secretion may be implicated. Fitness, salivary cortisol levels (0 and 30 min postawakening, midday, 5 p.m., and 9 p.m.), and cognitive function were determined in a group of amnestic MCI patients (n = 39) before and after a three-month exercise program (n = 19) or usual care (n = 20). At baseline, fitness measures were positively correlated with peak levels of cortisol and a greater fall in cortisol concentration from peak levels to midday. The exercise intervention successfully increased fitness and resulted in a greater fall in cortisol concentration from peak to midday, compared with the control group. The exercise intervention enhanced indices of executive function, although memory, mood, and functionality were not affected. |
