Abstract
The purpose of this study was to examine the relationship between ACL injury risk factors in unanticipated cutting and decelerating. Three-dimensional kinematics and ground reaction forces were collected on eleven females (22±2yrs, 1.67±0.08m, 68.5±9.8kg) during two unanticipated tasks. Paired samples t-tests were performed to compare dependent variables between tasks. Spearman rank correlation coefficients were calculated to analyze the relationship between peak internal knee adduction moment and peak anterior tibial shear force during two unanticipated tasks. Significantly greater knee abduction angles, peak knee adduction moments, and peak anterior tibial shear forces were observed during cutting (p≤0.05). A strong positive correlation existed between decelerating anterior tibial shear force and cutting anterior tibial shear force (ρ=0.67), while correlations between decelerating knee adduction moment and cutting knee adduction moment and decelerating anterior tibial shear force and cutting knee adduction moment were not significant. In situations where time management is a necessity, and only one task can be evaluated, it may be more appropriate to utilize an unanticipated cutting task rather than an unanticipated ...
