A common symptom of overtraining is persistent fatigue or extreme exhaustion, which can negatively affect physical performance. Individuals may experience heightened levels of perceived effort, decreased motivation, and increased irritability. Overtraining can also manifest through physical symptoms like soreness, heightened injury risk, or sleep disturbances. Additionally, hormonal imbalances can lead to mood swings and decreased appetite. Recognizing these symptoms is crucial for athletes and fitness enthusiasts to prevent further fatigue and promote recovery through rest and proper nutrition. Balancing training intensity and recovery is vital for optimal performance.
