What is one potential physical symptom of Over-Training Syndrome?

Muscle tenderness is a notable physical symptom of Over-Training Syndrome, which occurs when an individual engages in excessive training without adequate rest or recovery. This condition can lead to a range of physical signs, and muscle tenderness is one of the most common manifestations. When the body is subjected to high levels of stress and strain from overtraining, the muscles may become inflamed and sensitive to touch. This tenderness can result from the breakdown of muscle tissue that occurs during intense exercise, coupled with an inadequate recovery period that prevents proper healing.

In contrast to muscle tenderness, decreased flexibility, improved posture, and increased energy levels do not align with the typical symptoms of Over-Training Syndrome. Decreased flexibility can result from other factors, but it is not a direct symptom of this syndrome. Improved posture is generally associated with strength training and increased muscular balance, rather than overtraining. Lastly, increased energy levels contradict the fatigue and lack of recovery typically experienced by someone suffering from Over-Training Syndrome. Instead, individuals often feel fatigued, which makes muscle tenderness a more fitting indication of this condition.
