Summary

This study tested how a single bout of running in extreme cold (-10°C) affects red blood cell clumping in 30 healthy young men. Half ran in a cold chamber, half in neutral air. Researchers measured blood samples to see how cold exercise changes blood flow and oxygen transport. The study is complete and purely observational, with no treatment or health benefit tested.
