Data obtained from pre-season screening of professional soccer (n=26), basketball (n=19) and hockey (n=21) players were statistically compared using ANOVA and a modified t-test. Results of isokinetic. Aerobic and anthropometric tests were found to be significant (p < .017). A discriminant analysis was then applied to the following variables: surface area (SA), VO2, Vm, total leg strength (TLS = knee extension + knee flexion + hip adduction + hip abduction + hip flexion tested on a CYBEX at 10 RPM ), and the ratio of hip abduction to total leg strength (HAB / TLS); 84.8% (56 / 66) of the players were accurately ranked into their respective sports. The means and standard errors were:

The Mahalanobis d square for the three equations formed was 165.9 (df=10). This multi-factorial approach to sport profiling allows for the mathematical combination of variables to determine physical and physiological requirements of a professional sport. Neither isolated characteristics nor analysis by group means identified the individual differences which exist within a given sport.
