The Analysis of Greco-Roman Wrestling Injuries by Regions and the Effects of Injury Rehabilitation Training Programs in Athletic Greco-Roman Wrestlers (Focus on Investigation and Experimental Study) Kim, Bong Ho Department of Sports Medicine Graduate School, Catholic Kwandong University Supervisor: Professor Rhi, Soung Yob This study aimed to (1) analyze the epidemiological characteristics of sports injuries in Korean Greco-Roman wrestlers by body region, injury type, severity, and reinjury patterns, and (2) experimentally verify the effectiveness of a complex power based rehabilitation training program targeting injury-prone regions in elite wrestlers. Study 1 employed a nationwide cross-sectional online survey of wrestlers registered with the Korean Olympic Committee in 2025. Injury incidence, distribution by body region, reinjury frequency, suspension duration, intrinsic/extrinsic risk factors, and post-injury psychological responses were assessed using a structured Google Forms questionnaire.Study 2 utilized an experimental design in which wrestlers were assigned to either a complex power training group or a control group. Over the training period, changes in handgrip strength, trunk flexibility, balance, isokinetic shoulder and elbow strength, visual reaction performance, anaerobic power, and cardiopulmonary capacity were measured using standardized instruments. Results:Study 1 revealed that injuries were highly concentrated in the shoulder c omplex, cervical and lumbar spine, ribs, and upper extremities, with significant variation across age groups and team levels. Reinjury rates were notable, and re covery time differed markedly by body region and affiliation. Both intrinsic fact ors(e.g., muscular imbalance, flexibility deficits) and extrinsic factors (e.g., traini ng load, technical errors) contributed to injury occurrence.In Study 2, the compl ex power training program produced significant improvementsin handgrip strengt h and endurance, trunk flexion/ extension, isokinetic strength at multiple angular velocities, dynamic balance, whole-body and visual reaction times, and anaerobic power compared with the control group. These findings demonstrate enhanced fu nctional recovery of the upper-body dominant kinetic chain essential for Greco- Roman wrestling performance. Conclusion:This integrated investigation provides the first discipline-specific epid emiological profile of Greco-Roman wrestling injuries in Korea and offers empir ical evidence supporting a structured, phased rehabilitation program. The comple x power training protocol effectively restored functional capacity in injury-prone regions, suggesting its applicability as a standardized rehabilitation and return-to- play model for elite Greco-Roman wrestlers.
