Summary
This study looks at whether taking vitamin D and branched-chain amino acids (BCAAs) for 8 weeks can improve physical performance and reduce muscle fatigue in male long-distance runners. Researchers will measure changes in blood markers and running speed compared to a placebo group. The goal is to see if these common supplements offer real benefits for recovery and endurance.
