The purpose of this study is to review the kinetic characteristics and the injury mechanisms of shoulder, and to present ex-ercises for preventing injuries. It is reviewed that proper positioning of scapular and centering of humeral head to glenoid fos-sa is more important to control arm activities. The glenohumeral joint is highly mobile, with little bony or ligamentous stability provided in midrange. But 54% of the force delivered to the implement through the shoulder is created by the lower legs, hip and trunk, human shoulder is injured easily. To prevent injury, the function of scapula and glenohumeral joint must be main-tained normally and protected by preventing exercises. For stabilizing scapular, lower leg-trunk stabilizing exercises, clock ex-ercise, towel slide, fitter shift exercise, lawnmower exercise were recommended. For reducing impingement and recovering rhythm of scapula and humeral head, ball exercise, PNF exercise, alternating serratus anterior punc exercise, plyometric ex-ercise, lat exercise were recommended. For strengthening lower legs, hip and trunk, hip-trunk exercise, trampolin exercise, run-ning machine, agility exercise, jump exercise, slide-board exercise, pitter exercise were encouraged and for power, theraband and medicine ball exercise were recommended. Finally, for the proper functioning of rotator-cuff, theraband and body-blade exercise were encouraged.
