YEADON, M.R., 1993. The biomechanics of twisting somersaults. Part IV: partitioning performances using the tilt angle. Journal of Sports Sciences, 11 (3), pp. 219-225
A method is presented for determining the contributions made by contact and aerial twisting
techniques in filmed performances of twisting somersaults. An 11-segment simulation model is used
to determine the effects of removing asymmetries about the sagittal plane. Tilt contributions are
determined for four competitive movements performed by an elite trampolinist. It is found that even
in movements in which the twist is evident at takeoff, aerial techniques make a greater contribution
than contact techniques.
