Abstract: Physical exercise (PE), notoriously, promotes a state of general well-being, throughout the
entire human lifespan. Moreover, maintaining an adequate and regular PE habit results in a powerful
preventive factor towards many diseases and may also help in managing existing pathological conditions.
PE induces structural and functional changes in various parts of the body, determining biological
and psychological benefits. Additionally, in the elderly, PE might represent a remarkable tool
reducing cognitive impairments related to the normal aging processes and it has also been found to
have an impact on neurodegenerative diseases such as Alzheimer’s disease. The present review aims
to provide an overview of PE effects on the hippocampus, since it is one of the brain regions most
susceptible to aging and, therefore, involved in diseases characterized by cognitive impairment.
