Abstract：
OBJECTIVES:The objectives of this study were to explore the relationship between acute (1 week) and chronic (4-week average) bowling workloads and injury risk in National Development Programme fast bowlers, and to investigate individual differences in the relationship between acute:chronic workloads and injury. DESIGN:Prospective cohort study. METHODS:Bowling workloads and injury data were collected prospectively for 29 male fast bowlers (age range 15-18) on a National Programme over two years. Workload variables were calculated and the likelihood of injury and individual effects were explored using a generalised linear mixed effects model and magnitude-based inferences. RESULTS:Acute:chronic workloads of 109-142% (relative risk [RR]: 1.46, 90% CI: 0.93-2.29; likely harmful), and ≥142% (RR: 1.66, 90% CI: 1.06-2.59, likely harmful) were associated with a substantial increase in injury risk compared with the reference quartile (<87%). A high chronic workload (>83 balls) substantially attenuated the influence of a high (>108%) acute:chronic workload ratio on injury risk (RR: 0.35, 90% CI: 0.17-0.74). Significant individual differences in the acute:chronic workload-injury relationship were evident. CONCLUSIONS:The present study provides further evidence of the association between 'spikes' in workload and injury risk, but also demonstrates that this relationship is individual-specific and dependent on the level of chronic workload. Support teams for fast bowlers should monitor bowling workloads to avoid rapid fluctuations but should also base decisions on individualised data.
