How Fatigue Accumulates

Direct Answer
Fatigue accumulates when training stress exceeds the body’s ability to recover and adapt within a given timeframe.

Primary Sources
Fatigue arises from muscular damage, metabolic depletion, nervous system strain, psychological stress, and insufficient recovery.

Acute vs Chronic Accumulation
Short-term fatigue supports adaptation when managed appropriately. Chronic accumulation suppresses performance and increases injury risk.

Practical Relevance
Training systems should intentionally manage fatigue through load regulation, recovery strategies, and periodic reduction in stress.
