Norm-referenced Criteria for Strength of the Upper Limbs for the Korean High School Baseball Players Using Computer Assisted Isokinetic Equipment

Abstract

The purpose of this study is to set the norm-referenced criteria for isokinetic muscular strength of the upper limbs (elbow and shoulder joint) for the Korean 83 high school baseball players. HUMAC NORM (CSMI, USA) system was used to obtained the value of peak torque, peak torque per body weight. The results were presented as a norm-referenced criterion value using 5-point scale of cajori by 5 group (6.06, 24.17, 38.30, 24.17, and 6.06%). The provided criteria of peak torque and peak torque per body weight, set through the computer isokinetic equipment, are very useful information for high school baseball player, baseball coach, athletic trainer and sports injury rehabilitation specialists in injury recovery and return to rehabilitation, to utilize as an objective clinical assessment data.
