What is a potential effect of overtraining on athletes?

Overtraining can lead to a range of negative effects, one of which is chronic fatigue and a decline in performance. This occurs because the athlete does not allow sufficient time for recovery and adaptation, leading to physical and mental stress accumulating over time. The body's mechanisms become overwhelmed, resulting in decreased energy levels, prolonged fatigue, and hindered recovery processes. Consequently, athletes may experience a drop in performance, difficulty in training, mood disturbances, and even injury, all of which are associated with the overtraining syndrome.

In contrast, increased energy levels, enhanced physical condition, and improved mental focus are outcomes associated with proper training and recovery. When an athlete overtrains, these positive outcomes are not achieved, highlighting how necessary adequate rest and recovery are for overall performance enhancement.
