Which of the following is a potential outcome of excessive high-intensity training without adequate recovery?

Excessive high-intensity training without adequate recovery can lead to chronic fatigue, which is characterized by a persistent feeling of tiredness that does not improve with rest. This occurs because the body needs time to recover and repair the muscle tissues that are broken down during intense workouts. When recovery is insufficient, the physiological stress induced by overtraining accumulates, leading to a decrease in physical performance, altered hormone levels, and heightened levels of fatigue. Chronic fatigue can also impact mental focus and motivation, further exacerbating the negative effects of insufficient recovery on an individual's training regimen. Recognizing the signs of chronic fatigue is crucial for athletes and fitness enthusiasts alike to prevent burnout and optimize their training outcomes effectively.
