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. The provided criterion are very useful information for baseball coach, athletic trainers, baseball players, and sports injury rehabilitation specialists
