List common signs of overtraining in athletes.

• A. Fatigue, reduced performance, prolonged soreness
• B. Fatigue, reduced performance, prolonged soreness, sleep disturbance, mood changes, and increased resting heart rate
• C. Resting heart rate decreases and mood improves
• D. No signs appear

Answer: (B)

Overtraining shows itself through a range of signs across physical and psychological areas, not just one symptom. When training loads exceed what the body can recover from, fatigue persists, performance drops, and muscles remain unusually sore. Add to this sleep disturbance and mood changes, which are common as recovery becomes harder, and you’ll often see an increased resting heart rate as the autonomic system stays in a stressed state. This combination points to an overwhelmed recovery process, which is what overtraining reflects. The other options miss some of these key indicators: one lists only a subset and ignores sleep and mood changes and the heart rate response; another wrongly suggests resting heart rate would fall and mood would improve; and saying there are no signs contradicts the reality that overtraining presents with multiple identifiable changes.
