Exercise-Induced Muscle Damage (EIMD) occurs when intense physical activity leads to microscopic tears in muscle fibers. This damage is a normal response to exercise, especially during activities that involve eccentric contractions, such as running downhill or lifting weights. Symptoms often include muscle soreness, stiffness, and temporary decreases in strength. The body repairs these damaged fibers, leading to muscle growth and increased strength over time. Recovery from EIMD typically involves rest, proper nutrition, and hydration. Understanding EIMD is important for athletes and fitness enthusiasts to optimize their training and recovery strategies while minimizing the risk of injury.
