Overtraining syndrome is a chronic condition that occurs when one trains excessively without sufficient rest. It results in decreased performance, profound fatigue physically and mentally, and endocrine changes.
Also known as “staleness” or “burnout,” it manifests as persistent fatigue, a lowered immune system, mood swings, and an increased resting heart rate. It appears to be a hormonal problem because it affects hormone responses. You can correct it by taking weeks or months of reduced training, scheduled rest, mental reinforcement, and proper nutrition. You can avoid it by structuring your training in phases, monitoring how much you train, and prioritizing sleep and stress management.
