Abstract : This report covers progress made in the development of a model to predict both injury and performance during basic training. Previously, we developed preliminary performance enhancement and metabolic demand models to complement stress fracture models developed earlier. In this report, we describe our work in the further development of the performance model, with a focus on run performance. We also introduce a statistical prediction method to compare our model accuracy with, and describe the development of preliminary overuse and acute injury models. We further refine the software conceptual design and describe the implementation of a simplified version of the software. Additional datasets were also acquired and organized, which were used for model development and validation.
