Exercise Remodels Cardiac Nerves Differently on Each Side in Rats
A rat study found that 10 weeks of moderate aerobic training was associated with structural changes in the paired stellate ganglia, which help regulate heart activity. The changes differed between the left and right sides; whether similar patterns occur in humans is unknown.
- Rats underwent 10 weeks of moderate aerobic training.
- Ganglion neuron numbers and sizes differed between sides.
- Human relevance and functional effects remain unknown.
Researchers examined stellate ganglia—the paired nerve-cell clusters involved in autonomic regulation of the heart—in rats after 10 weeks of moderate aerobic training. Using three-dimensional stereological analysis, they assessed neuron numbers and size. The source does not report the number of animals studied.
