A) Background & Objective: Prevention of skeletal-muscular injuries is the main challenge in sports science studies; accordingly, internal risk factors cause more than 70% of musculoskeletal injuries. The results of some studies have shown that defects in motor performance are known as one of the main causes of endogenous injuries, which itself is caused by the instability of dynamic body posture. The purpose of this study was to investigate the effect of dynamic neuromuscular stability (DNS) exercises on landing error scoring system (LESS) and single-leg squat test scores in male student athletes.
b) Methods: The study method in this research is semi-experimental with a pre-test and post-test design with a control group. The number of 40 secondary school male students of physical education schools in the educational districts of Mashhad as The research sample participated in this research and were randomly assigned to the experimental group (20 people) and the control group (20 people). Before and after the training intervention, the score variables of single leg squat test and landing error scoring system (LESS) were evaluated. The experimental group performed dynamic neuromuscular stability exercises for 6 weeks (3 sessions per week and 45 to 60 minutes each session), while no intervention was done in the control group. The exercises of retaining DNS patterns and transferring from one pattern to another pattern were performed based on the order of occurrence of the patterns in the baby and based on the degree of difficulty, and at the same time teaching, correcting and performing deep breathing in all patterns for about 40 minutes. Exercises included diaphragmatic breathing, lying on the back 90-90, lying on the stomach, rolling over, sitting on the side, sitting on an incline, tripod, kneeling, squatting and standing up. In order to analyze and check the data, the inferential statistics method of covariance analysis was used (P<0.05).
c) Results: According to the results of this research, after six weeks of DNS exercises, there is a significant and positive difference in the single leg squat test scores (P=74/24,F=0.001) and the single leg landing test score (P=90/62, F=0.001) compared to the experimental group compared to before the implementation of the training protocol and also compared to the control group (P<0.05).
D) Conclusion: In general, it can be concluded that this study shows the value of fundamental movement with DNS approach in improving functional movements. Developing skills in fundamental movements can probably be useful for more effective practice of more specialized functional movements such as sports skills. However, more studies are needed to make a firm opinion on this matter. Currently, it can be concluded that it is better to periodically use DNS exercises in the annual training program of young athletes. This probably helps prevent endogenous injuries caused by motor dysfunction and neuromuscular disorders more effectively. The reason for this is that the origin of many anatomical defects and biomechanical errors is neuromuscular disorder. It should be noted that developing skills in fundamental movements is the starting point of sports injury prevention and this can be achieved through DNS exercises.
