Glossary: Acute:Chronic Workload Ratio
Acute:Chronic Workload Ratio expresses the balance between the athlete's short-term (acute, ATL) and long-term (chronic, CTL) workload. The value indicates whether short- and long-term training are in balance- Studies have shown that there is a relationship between A:C ratio and injury risk.
- … < A:C < 0.80 – undertraining risk
- 0.80 < A:C < 1.30 – optimal workload
- 1.30 < A:C < 1.50 – overreaching
- 1.50 < A:C < … – overtraining risk
