Training adaptation depends on the balance between stress and recovery. When recovery is insufficient, fatigue accumulates, performance stagnates, and the risk of injury or burnout increases. Understanding fatigue is essential for long-term progress.
This hub explores how different types of fatigue develop, how recovery works at the muscular and nervous system level, and how to recognize and prevent overtraining before performance declines.
Training Stress & Fatigue Fundamentals
Fatigue is a multifactorial process involving muscular, neural, and systemic components.
