Effect of Six Weeks Reactive Neuromuscular Training on Balance and Performance in Volleyball Players with Anterior Cruciate Ligament Reconstruction: A Randomized Trial

Abstract

Background: Volleyball players undergoing anterior cruciate ligament (ACL) reconstruction are susceptible to balance and performance deficits. Objectives: This study investigates the effectiveness of a six-week reactive neuromuscular training (RNMT) program in enhancing balance and performance in these athletes. Methods: This quasi-experimental study examined male volleyball players in Quchan (2022 - 2023) with a history of ACL reconstruction. Thirty players meeting the inclusion and exclusion criteria were purposefully selected and randomly assigned to an exercise group (n = 15) or a control group (n = 15). Balance (Y-Balance Test) and performance (triple hop test, single-leg 6-meter timed hop test, and vertical jump height) were measured pre-and post-intervention. The exercise group underwent a 6-week RNMT program (3 sessions/week, 60 minutes/session). Results: The findings demonstrated a significant improvement in balance and performance in the experimental group from pre-test to post-test following RNMT training. Additionally, the results revealed a significant difference in balance and performance between the experimental and control groups. Conclusions: These findings suggest that six weeks of RNMT can significantly improve balance and performance in volleyball players post-ACL reconstruction, potentially reducing reinjury risk and enhancing their return to play.
