Development of an athlete/shoe/surface-related injury prediction model for American football. 2. Use of ratiometric analysis, thresholded dimensionless numbers and scoring of qualitative variables

Abstract

For pt.1 see ibid., p.150-3 (1995). This is pt. 2 of a two-part paper in which athlete, footwear, playing surface, and interface factors are considered as a system in assessment of parameters for injury prediction. Pt. 1 identified and categorized qualitative and quantitative factors in the athlete/shoe/surface system important for injury prediction, using the sport of American football as an example. Here, the authors propose the development of a comprehensive model for injury prediction in football, based on experimentation and current knowledge, that incorporates thresholded dimensionless ratios of quantitative injury variables and subjective scores for qualitative variables.
