Overtraining Syndrome is a condition that occurs when an athlete trains too hard without allowing adequate time for recovery. This can lead to a decline in performance, fatigue, and increased risk of injuries. Symptoms may include persistent muscle soreness, mood changes, and sleep disturbances. To prevent Overtraining Syndrome, it is essential to balance training intensity with rest and recovery. Athletes should monitor their training loads and listen to their bodies. Incorporating rest days and proper nutrition can help maintain optimal performance and overall well-being.
