Aerobic Exercise, Hippocampal volume, and Spatial Memory
March 4, 2009
It has been know for some time that aerobic exercise and physical activity helps to increase cognitive function and perhaps delay onset of Alzheimer’s disease. A recent study provides some explanation for how this might occur.
It is known that deterioration of the hippocampus occurs as part of the aging process. The hippocampus (i) is the structure deep in the middle of the temporal lobe that helps to form new memories and spatial memory. Changes in the structure and function occur in the hippocampus with advanced age, chronic stress, and Alzheimer’s disease. In contrast, studies indicate an enriched environment that includes physical activity can lead to neurogenesis in the hippocampus.
A recent study by Erickson and colleagues (2009) investigated high versus low levels of aerobic exercise in non-demented older adults on volume of the hippocampus and on spatial memory. Results indicate that higher fitness levels were associated with larger left and right hippocampi and larger hippocampi and higher fitness levels were related to better spatial memory performance.

Regardless of age, weight or athletic ability, aerobic activity is good for you. As your body adapts to regular aerobic exercise, you'll get stronger and more efficient. Consider 10 ways that aerobic activity can help you feel better and enjoy life to the fullest.
# Keep excess pounds at bay. Combined with a healthy diet, aerobic exercise helps you lose weight — and keep it off.
# Increase your stamina. Aerobic exercise may make you tired in the short term. But over the long term, you'll enjoy increased stamina and reduced fatigue.
# Ward off viral illnesses. Aerobic exercise activates your immune system. This leaves you less susceptible to minor viral illnesses, such as colds and flu.
# Reduce health risks. Aerobic exercise reduces the risk of many conditions, including obesity, heart disease, high blood pressure, type 2 diabetes, stroke and certain types of cancer. Weight-bearing aerobic exercises, such as walking, reduce the risk of osteoporosis.
# Manage chronic conditions. Aerobic exercise helps lower high blood pressure and control blood sugar. If you've had a heart attack, aerobic exercise helps prevent subsequent attacks.
# Strengthen
