The acute-to-chronic workload ratio compares a short recent training window, often seven days, with a longer baseline, often about four weeks. It is a planning signal for spotting rapid workload changes, not a medical diagnosis or a standalone injury prediction.
There is no universal safe ratio that applies to every athlete, sport, or workload method. Use your own stable training history, modality-specific load, recovery trends, and symptoms to judge whether a recent increase is appropriate.
Track running and lifting separately first, then add a common internal-load measure such as session RPE multiplied by duration if you need one combined view. Mileage and lifted tonnage should not be added together as if they were the same unit.
