In recent years the role of the pelvic muscles and back muscles as part of the central region in the pathology and treatment of sports injuries of the lower extremities has been noted. Deformity of the jenu varum is considered one of the most common footballer injuries. Since the most common elements abductor and adductor thigh muscles are involved in this problem, therefore, the purpose of this study was to compare the enduranceof core stability muscles between male football players with and without jenu varum abnormality. In this study, trunk flexor and Extensor and lateral flexor strength of the 50 male football players involve 25 with jenu varum (age 22 ± 1.4 yr, height 176.4±4.3 cm, weight 72.7±4.1 kg) and 25 males without the jenu varum (age 23 ± 1.7 yr, height 175.5±3.9 cm, weight 74.6±3.2 kg) were measured. To measure the muscle in both groups endurance by Digital Stopwatch, by McGill and Biering-Sorensen tests was used. Trunk flexor, extensor, and lateral flexor strength in football players with jenu varum abnormalities compared with non-infected footballers would be significantly less (P<0.05). The results of this research indicate that it is probably a major factor in reducing the core stabilization muscles strength the risk of being infected with knee jenu varum footballers. This should be confirmed in future comparative studies. Increased strength of these muscles is likely to reduce the risk of knee jenu varum.
