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

Like all TRIMP-related calculations, these calculations are based only on duration and heart rate. Different sports and alternative training can therefore not be considered.
