Fatigue can significantly influence exercise performance by impairing physical and mental capabilities. When a person is fatigued, their body experiences a reduction in strength, endurance, and overall responsiveness. This can lead to decreased motivation, increased perceived exertion, and a heightened risk of injury during physical activity. It is essential for individuals to listen to their bodies; if they feel fatigued, they may need to rest or modify their exercise intensity. Proper recovery, including adequate sleep and nutrition, is critical for maintaining peak performance and achieving fitness goals, as ongoing fatigue can hinder progress.
