Understanding Cerebral Blood Flow Dynamics for Alzheimer's Disease Prevention Through Exercise

Dementia is one of the leading causes of disability worldwide. Underlying biological mechanisms are crucial in preclinical stages of Alzheimer's disease (AD). Alterations in cerebral blood flow (CBF) and their relationship with AD blood-based biomarkers may be fundamental at early stages of the pathology. Physical exercise is a trigger to modify these biological mechanisms. Therefore, flADex aims to examine the acute effects of different types of exercise (resistance vs. aerobic vs. control) on CBF, AD blood-based biomarkers, and its cognitive implications in older adults. The hypothesis is that acute resistance or aerobic exercise will fluctuate levels of blood-based biomarkers, and will exert acute CBF changes combined with cognitive implications.
