The purpose of this study was to present the lumbar muscular strengthening program(LMSP), and to identify the changes in isokinetic muscular function(MF) in hip joint, physical fitness, sports-specific skills according to the change in lumbar isokinetic MF. Participants were 34 male middle school soccer players, and randomly assigned to exercise(EG, n=17) and control group(CG, n=17). LMSP consisted of sit-up, hyper-extension, leg raise, superman posture was applied to EG for 12 weeks, everyday, 20~27 min/day. MF in lumbar and hip joint was repeatedly measured with isokinetic dynamometer before and after application of the program flexibility, balance, the time required during dribble, throwing distance, ball speed after in-step shooting were measured simultaneously. As a result, lumbar flexion peak torque, lumbar flexion average power, and lumbar extension total work in EG were significantly increased, and lumbar extensor/flexor(E/F) ratio in EG was significantly decreased(p<.01) after application of the program. However there were no significance and no meaningful changing trends in isokinetic MF in hip joint, physical fitness variables, and sports-specific skills except for flexion peak torque in the dominant-side hip joint. ill conclusion, LMSP in this study was effective in improvement of lumbar MF. And additional exercise program after 12th week or extra exercise program based on the training principle of specificity should be applied for meaningful changes in MF in hip joint, physical fitness, sports-specific skills. The results of E/F ratio in lumbar and hip joint suggested that intervention program for prevention of sports injury in growing soccer players should be introduced.
