exercise, brain, cognition, omics, molecular markers and functionality in people at risk of mild cognitive impairment

Conditions: Mild Cognitive Impairment; Alzheimer Dementia

Summary: this project aims to examine the effect of a 5-month period supervised exercise intervention on brain, cognition, omics, molecular markers and functional status in older people at risk of mild cognitive impairment. secondarily, the effect of this intervention on antioxidant capacity, lipid metabolism and glucose, physical health (functional capacity, blood pressure, body composition) and mental (quality of life and depression) will be studied, as well as other factors risk (genetic and biological) for the development of alzheimer. a total of 100 people aged between 65 and 75 years old at risk of mild cognitive impairment will be randomly distributed in the supervised exercise intervention group (n = 50) and control group (n = 50). the design will include a 5-month intervention with measurements at pre and post intervention and a third measurement (retest) after 3 months of completion. the multicomponent supervised exercise program will include aerobic, strength, cognitive and coordinative-agility-balance works, and progression will be established in different load parameters (frequency, volume, intensity, density). therefore, randomized controlled studies are needed to know the specific effect of dose-response considering the various dimensions in parallel such as neuroimaging, cognitive status and omics. this will allow us to understand from a comprehensive perspective the causes and mechanisms underlying the response. this project will significantly increase scientific knowledge about the role of exercise on brain as a therapeutic measure in people at risk of mild cognitive impairment from a multidimensional perspective. the project will have a significant impact at social and economic level by transferring the study findings to social and health setting by means of agents and networks provided for the project.
