Aerobic exercise can help improve memory by increasing brain size.
Aerobic exercise can help improve memory by increasing brain size.
A recent study found that aerobic exercise, like walking or cycling, can actually increase the size of a part of the brain called the hippocampus in older adults. This part of the brain is important for memory. The study showed that participating in regular aerobic exercise can lead to improvements in memory and may even reverse some of the age-related loss in brain volume. This is great news for seniors looking for simple ways to maintain their memory and brain health. Regular exercise could be a key part of keeping your mind sharp as you age.
Use the full description to understand the study design, methods, and the limits of the findings.
This study involved 120 older adults who were divided into two groups: one group did moderate aerobic exercises, and the other did stretching. Over a year, those in the aerobic group increased the size of their hippocampus by about 2%, while the stretching group saw a decrease in size.
The study used brain scans to measure changes, highlighting how exercise can specifically grow the anterior hippocampus, crucial for memory.
It showed aerobic exercise led to increased fitness levels and was linked to higher levels of a brain chemical called BDNF, which supports brain health.
While promising, the study focused only on a specific age group and exercise type; results may vary individually.
Seniors should consider discussing with their healthcare provider how incorporating regular aerobic exercise might benefit their brain health.
