Exercise doesn't just strengthen the heart. It rewires it
Researchers have discovered that regular aerobic exercise physically remodels the nerves regulating the heart in a side-specific manner. This study on rats reveals that exercise changes the structure of nerve clusters differently on the left and right sides of the body.
Why it matters
Understanding these specific neural changes could lead to more precise medical treatments for heart conditions like arrhythmias and stress-induced heart syndrome.
Regular exercise may benefit the heart in a way scientists are only beginning to understand. Beyond improving cardiovascular fitness, new research suggests that moderate aerobic exercise reshapes the nerves that regulate the heart. The findings could eventually help doctors develop more precise treatments for common heart conditions.
