Abstract
Background: Anterior cruciate ligament (ACL) rupture is one of the severe and complex knee injuries that usually occur in soccer. The Sportsmetrics Soccer training (SMST) is one of the successful protocols for preventing knee injury and enhancing performance for soccer players. The aim of this study was to compare the effect of the SMST injury prevention protocol on the performance of soccer players with and without anterior cruciate ligament reconstruction (ACLR).
Methods: The method of this research is a semi-experimental type, and the samples included 42 soccer players with an age range of 18-30 years old. These players had 3 years of regular exercise in soccer and were divided into two groups of 21 subjects (with and without ACLR). Physical performance was determined by the Illinois agility test, 40-yard sprint test, and Sargent vertical jump test in both groups before and after six weeks. SMST training was done in three sessions of 90 minutes. Statistical analysis was performed to compare intra-group differences with the dependent t-test and inter-group differences with covariance analysis test (P≤0.05).
Results: The dependent t-test results in both groups after six weeks of SMST training showed a significant difference in speed (P=0.01), agility (P=0.01), and explosive power (P=0.01) factors. The results of the covariance analysis showed that after six weeks of training, there was no significant difference between the records of speed (P=0.57), agility (P=0.07), and explosive power (P=0.71) tests in the two groups.
Conclusion: The main factor that increased performance indicators in the subjects was the similarity between the SMST protocol factors and performance evaluation tests. SMST training is highly recommended for healthy and ACLR players, as it helps to improve the level of physical and athletic performance of soccer players while preventing injury and even re-injury of the ACL.
