Relationships between acute:chronic workload ratios and the risk of injury (±90% CI) in the current and subsequent weeks, and with 2-week average acute:chronic workload ratios
| Risk of injury (%)±90% CI | |||
|---|---|---|---|
| Acute:chronic workload ratio | Current week | Subsequent week | Two-week average |
| Very-low | 2.4±2.8* | 1.2±2.0* | 0.0±0.0 |
| Low | 5.0±2.5 | 8.9±3.4 | 7.6±3.1 |
| Moderate-low | 10.2±1.9 | 7.8±1.6 | 8.9±1.6 |
| Moderate | 7.2±1.5 | 7.8±1.6 | 6.9±1.6 |
| Moderate-high | 10.9±3.6 | 10.5±3.7 | 13.0±4.3† |
| High | 8.3±7.6 | 8.1±7.4 | 11.8±7.4‡ |
| Very-high | 16.7±14.4§ | 11.8±12.9 | 16.7±14.4¶ |
*Very likely (≥95%) and likely (≥75%) decreased risk of injury in the current and subsequent week than all other acute:chronic workload ratios.
†Very likely (≥95%) and likely (≥75%) increased risk of injury compared with low, moderate-low and moderate 2-week average.
‡Likely (≥75%) greater risk of injury than a moderate 2-week average.
§Very likely (≥95%) greater risk of injury than low, and very-low in the current week. Likely (≥75%) greater injury risk than moderate and high in the current week.
¶Likely (≥75%) greater risk of injury than low, moderate-low and moderate 2-week average.
