Which of the following is NOT a common sign of overtraining in sprint athletes?

• A. Persistent fatigue
• B. Reduced performance
• C. Sleep disruption
• D. Increased sleep quality

Answer: (D)

Overtraining happens when training stress outpaces recovery, so the body stays in a heightened state of stress. In sprint athletes, this often shows up as persistent fatigue that doesn't go away with normal rest, a noticeable drop in sprint performance, and sleep disruption such as trouble falling asleep, waking during the night, or feeling non-restorative sleep. These signs reflect the body’s struggle to recover from high-intensity work and accumulated fatigue.

In contrast, increased sleep quality isn’t a typical response to excessive training. If sleep quality improves, it usually points to adequate recovery or a well-managed training load rather than overtraining. So the option describing better sleep is not a common sign of overtraining.
