Table 5: Statistics of MRA model basic novice Group 1 for results of Republic Championship and the mean of three best season results. determination for the IJS scores are slightly higher for the basic novice Group 1 than for the advance novice and junior Group 2. The MRA models that analyze individual variables of the IJS score demonstrate that the principal components, representing the strength and speed predispositions of young skaters, as determined by field tests, have varying impacts on the overall score and its individual elements.
