The present study was conducted with the aim of determining the effect of pre-pubertal neuromuscular program on balance and performance of male footballers with dynamic valgus knee defect. In order to carry out this research, ۳۰ male teenage soccer players with dynamic knee valgus defects were selected and placed in two control groups (۱۵ people) and training groups (۱۵ people). After selecting the subjects, tuck jump variables were evaluated to determine the existence of knee dynamic valgus, stork and Y test to determine static and dynamic balance, as well as landing jump pattern, single leg triple jump and eight jump to determine lower limb function. After evaluating the tests, the subjects were divided into two control and training groups. The training group did the neuromuscular training program for ۶ weeks, and the control group also did the Raji training program during this period. After the completion of this course, the tests related to the pre-test stage were re-evaluated from the subjects. In order to experiment and inferential analysis of the data and to express the possible difference between the average groups in different stages of the research, the statistical method of analysis of covariance was used and to examine the difference within the group, the correlated t-test was used (P?۰.۰۵). The results of the studies showed that exercise has a significant effect on improving static balance (P=۰.۰۰۱), total score of dynamic balance (P=۰.۰۰۱), jump-landing pattern (P=۰.۰۰۱), single leg triple jump (P=۰.۰۰۷) and eight jump (P=۰.۰۰۱). Also, the examination of the difference between the groups showed that there was a significant difference between the two control and training groups in the studied variables (P?۰.۰۱). According to the results of the present study, it seems that the use of these exercises in the form of warm-up or specific exercises by these athletes can be effective in improving the performance of these athletes in addition to reducing the dynamic knee valgus defect.
