Background: The suplex technique in Greco-Roman wrestling requires exceptional hip eccentric strength for controlled execution and safe landing. Iso-inertial flywheel training offers a unique approach to develop eccentric strength through variable resistance and overload mechanisms that closely match the biomechanical demands of wrestling techniques. Objective: This study aimed to investigate the effects of iso-inertial flywheel training on hip eccentric strength and its impact on suplex technique success in senior Greco-Roman wrestlers. Methods: Twenty-four senior Greco-Roman wrestlers (aged 23-28 years) from four wrestling clubs in Kirkuk were randomly assigned to experimental group (n=12) receiving iso-inertial flywheel training, and control group (n=12) following traditional strength training. The 10-week intervention included 3 sessions per week of progressive flywheel training targeting hip extensors and flexors. Measurements included hip eccentric strength (isokinetic dynamometry), suplex success rate, execution quality, and landing control assessment. Results: The experimental group demonstrated significant improvements compared to the control group (p<0.05) in hip eccentric strength at 60°/s (242±28 to 311±32 Nm, +28.5%), hip eccentric strength at 180°/s (189±22 to 248±26 Nm, +31.2%), suplex success rate (64.2±8.1% to 87.5±6.3%, +36.3%), technique execution quality (6.8±1.0 to 8.9±0.7 points, +30.9%), and landing control score (7.1±0.9 to 9.2±0.6 points, +29.6%). Conclusion: Iso-inertial flywheel training effectively improved hip eccentric strength and suplex technique performance in Greco-Roman wrestlers. The training protocol enhanced both strength capacity and technical execution quality, demonstrating superior adaptations compared to traditional strength training methods.
