Comparison Analysis of Isokinetic Strength, Physical Fitness Profiles between Male Adolescents Greco-Roman and Free Style Wrestlers. The Journal of Kinesiology, 2017, 19(4): 19-27. [PURPOSE] This study was to investigate comparison analysis of isokinetic strength, physical fitness profiles between male adolescents; greco-roman and free style wrestlers. [METHODS] The subjects were twenty-one middle and high school wrestlers players. Subjects were classified into two group; greco-roman style group(n=9) and free style group(n=12). All subjects were tested for height(cm), weight(kg), body mass index(BMI, kg/m2), and isokinetic function, and physical fitness factors. [RESULTS] As results, peak tourque, %BW, Hamstring/Quadriceps ratio(HQR) were not significantly different between the greco-roman and free style group. The relative grip strength showed a higher tendency in the free style group than in the greco-roman style group(p=.068). The sergeant jump was observed a significantly high in the free style group than in the greco-roman style group(p=.048). The absolute back strength was observed a significantly high in the in the greco-roman style group than free style group(p=.043). [CONCLUSIONS] This study demonstrated that the physical factors were different between wrestling style. A more detailed study of greco-roman and free style in adolescent and adult wrestlers are required to improve performances in the future.
