Abstract

Background and Aim: The knee joint has been introduced as the most vulnerable part of the body in volleyball. the aim of this research is to the effect of 6 weeks of neuromuscular training on the landing-jumping pattern, balance, and knee proprioception of female volleyball players with high and low risk of anterior cruciate ligament injury.
Methods: forty female volleyball players were selected into two groups of high and low-risk ACL injury using the LESS test, and then each group was divided into two training and control groups. Dynamic and static balance, knee proprioception, and jump-landing patterns were evaluated. Neuromuscular exercises were performed for six weeks by the training group and then, the post-test was performed. dependent t-tests and covariance analysis were used to analyze the data.
Results: The results of the research showed that neuromuscular exercises have a significant effect on static and dynamic balance, proprioception, and landing-jump mechanics, But the effect of this exercise on the research components among the experimental groups (except for the landing error component (p = 0.001)) was not significant.
Conclusions: neuromuscular exercises improve dynamic and static balance, proprioception, and landing-jumping mechanics in both high and low-injury risk groups, and the effect of these exercises on the landing-jump component in the group with high injury risk is greater than in the group with low injury risk. This difference can be attributed to the basic neuromuscular weakness in the group with high injury risk.
