Lim, S.K., Kim, Y.J., Kim, B.G. Norm-referenced criteria of the trunk flexor and extensor strength for the Korean pro-baseball players. Exercise Science. 17(4): 473-482, 2008. The purpose of this study was to investigate norm-referenced criteria of the isokinetic trunk flexor and extensor strength for the Korean pro-baseball players. One hundred forty five pro-baseball players were participated in this study. They didn't have any medical problem at the low back. They performed isokinetic trunk flexion/ extension test at 30°/s. Cybex 770 system was used to obtained the value of peak torque, peak torque % body weight, total work, total work % body weight, average, and average power % body weight. The results were presented as a norm-referenced criterion value using 5-point scale. On the basis of the results analyzed in this study, the conclusion were drawn as follow. Norm-referenced criteria that had suggested in this study can do subjective evaluation of the trunk flexor and extensor strength for the Korean pro-baseball players, if isokinetic strength test may use by the same method.
