The Quintuple Axel: What Are the Risks?
Abstract
Before the International Skating Union (ISU) can consider giving quintuple jumps base values and grades of execution, they should consider the physical risks to their athletes that these jump elements can have. Using approximate heights and weights for a skater, the limits of the most difficult jump, the quintuple axel, will be modelled to determine some of the injuries that could occur from training, landing, and mis-landing it. This paper will use the data from the previous associated paper, [1], for these models, to attempt to determine the severity of the risks, which the ISU should take into consideration before assigning scores which could encourage or discourage skaters to chase the new “impossible” jump.
