What is NOT a sign or symptom of overtraining?

  1. Prolonged fatigue

  2. Improved performance

  3. Mood disturbances

  4. Unexplained weight loss

The correct answer is: Improved performance

Improved performance is not a sign or symptom of overtraining. In fact, overtraining typically leads to a decrease in performance, fatigue, and other negative physical and psychological effects. When an individual is overtrained, their body is unable to adequately recover, which can result in fatigue that hinders strength, endurance, and overall athletic performance. In contrast, prolonged fatigue, mood disturbances, and unexplained weight loss are all commonly associated with overtraining. Prolonged fatigue reflects the body's inability to recover after intense training, while mood disturbances may arise due to hormonal imbalances and stress. Unexplained weight loss can occur as the body may start to break down muscle tissue in a catabolic state due to chronic stress and inadequate recovery. Therefore, improved performance clearly stands apart from the other symptoms typically seen in overtraining scenarios.
