Background: The study of the factors affecting the enhancement of physical performance of individuals has been a subject of research for many years. Knee joint plays an essential role in supporting the body and transferring its weight during various activities. Therefore, it is important to fully understand knee anomalies to correct and reduce the effects of these abnormalities. The nature of football exercise can cause postural disorders in the athletes' joints, especially the knee joint. Genu varum deformity is the most common disorder among football players which can be improved by facilitating certain corrective exercises. Among these exercises, the national academy of sports medicine (NASM) method has previously shown effectiveness in correcting many deformities including genu varum.
Methodology: Out of 200 Tabriz teenage football club players, 28 individuals with genu varum deformity were purposefully selected and divided into experimental and control groups. A resistance exercise based on the national academy of sports medicine (NASM) method was performed by the experimental group players for 8 weeks with 6 sessions per week and for 60 minutes per session.
Results: The results of the present study indicated a significant difference in genu varum severity between the control and experimental groups after exercise (p=0.05) with significant improves in the experimental group (p=0.001).
Conclusion: NASM based resistance exercises were capable of improving the state of genu varum deformity in teenage football players.
