Impact of Physical Activity on Brain Structure
Rumour: Physical Activity Can Influence Brain Shape
Recent discussions have suggested that physical activity may affect the shape of various brain regions.
Truth: Evidence Supports This Claim
This assertion is backed by research published in the British Journal of Nutrition. The study explored the relationship between exercise and the morphology of specific subcortical brain areas.
Study Overview
The trial involved children with an average age of 9.7 years, who participated in a physical fitness assessment. This assessment evaluated several factors, including cardiovascular fitness, muscular strength, lower-body strength, and speed agility.
Methodology
After completing the fitness test, participants underwent MRI scans to assess any alterations in the brain’s structure and size.
Findings
The results indicated that the physical fitness test led to notable changes in several subcortical regions of the brain. Specifically, researchers observed an increase in size in these areas following exercise. However, it is important to note that the overall brain volume remained unchanged before and after the fitness assessment.
