Aerobic exercise has a benefits for the heart, but some researchers are saying that an aerobic workout has also benefits for the brain.
The regular aerobic exercise such as walking can protect the memory center in the brain and the stretching exercise can cause the center called the hippocampus to shrink.
There is a study that involves men and women in their mid-60s. They were walking three times a week for a year and that lead to increase in the volume of the hippocampus, which plays an important role in the memory.
The control participants who take the stretching classes have shown drops in the volume of the hippocampus.
It’s possible to overcome the age-related decline in hippocampal volume with only moderate exercise.
The volume of the hippocampus is falling with age by between 1% and 2% a year, which leads to impaired memory and increased risk for dementia.
The results indicate that aerobic exercise is neuroprotective and that starting an exercise regimen later in life is not futile for either enhancing cognition or augmenting brain volume.
