The Influence of a Neuromuscular Exercise Program on Lower Limb Function and Knee 3D Alignment of Handball Male Players in single leg Landing

The knee positions could be parameters for injury of handball players in landing. Preventive exercise programs may decrease the injury of players. The aim of this study was to investigate the effect of a Neuromuscular Exercise Program on lower limb kinematics and single leg stability in male handball players. 40 handball players (Regular Training: n=20، height 187. 7±5. 5 cm; weight 89. 0±10. 1 kg; age 25. 4±13. 6 years; handball experience 11. 6±6. 4 years and neuromuscular training: n=20، height 185. 3 ±6. 4 cm; weight 86. 8±13. 6 kg; age 24. 2±3. 8 years; handball experience 10. 8±3. 3 years) were selected from two clubs participating in Iran Super League on 2012-2013. There were significant differences between the two groups in inward rotation of femur، knee valgus angles and single leg stability. No significant difference was found in knee flexion angle. Neuromuscular training can improve overall performance and reduce lower extremity valgus angle and internal rotation of the knee during landing with one leg. It may help handball players to prevent knee ligaments injuries، especially ACL، during competition season.
