Summary

This study looked at how a short period of rapid weight loss combined with exercise changes blood cells and immune cells in nine elite male wrestlers. The wrestlers lost about 4.3% of their body weight over five days, and blood samples were taken before and after exercise. The goal was to understand how these common wrestling practices affect the body's immune system.
