Abstract: This report covers progress made in the development of a model to predict both injury and performance during basic training. Previously, we developed a preliminary model that predicted the stress fracture rate and used biomechanical modeling, nonlinear optimization for muscle force, and bone structural analysis to estimate bone stresses and strains from kinematic and ground reaction force measures. We broaden the work to address not only the overuse injuries, but the performance enhancement and metabolic demands associated with training. The novel performance component of the model relates the amount and intensity of training to its outcome by dosage-response relationships that can account for the enhancement in physical strength, the improvement of performance due to learning or acquaintance to the activities, and fatigue effects. In addition, training activities were quantified in order to determine model input parameters. In this report we also describe a software conceptual design that comes with an intuitive interface, demonstrating the application of the model in realistic situations.
