Summary

This study tests whether taking dietary nitrate (found in beets) can help prevent muscle loss and weakness when a leg is immobilized in a brace for 14 days. Researchers will measure muscle function and energy use in 24 healthy young men. The goal is to find a simple, drug-free way to protect muscles during recovery from injury or illness.
