What are some signs of overtraining in individuals?

Prolonged fatigue is a key sign of overtraining, which occurs when athletes or individuals engage in excessive physical training without adequate rest and recovery. This fatigue can manifest both physically and mentally, leading to a decline in performance despite increased training intensity or volume.

When an individual is overtrained, their body becomes unable to recover fully, resulting in a persistent state of tiredness. This is often accompanied by other symptoms such as mood changes, irritability, disrupted sleep patterns, and decreased motivation to exercise. These signs serve as critical indicators that the body is not coping well with the training load, and it's essential for individuals to recognize this as a cue to modify their training plan to include adequate rest and recovery periods.

The other options pertain to positive outcomes often associated with regular, balanced training rather than overtraining. For instance, increased energy levels, improved performance, and enhanced sleep quality typically result from proper training and recovery, not from overtraining, where the body experiences significant stress and fatigue.
