Summary

This study looks at whether taking vitamin C or ibuprofen before exercise stops the body from building a natural protection against muscle soreness. 52 healthy adults will do a stepping exercise and be tested for muscle function and recovery. The goal is to see if these common supplements interfere with the 'repeated bout effect' that helps muscles adapt.
