The aim of this study was to investigate the effect of specific SportsMetricsTM training on core stability, tuck jump scores, and hops in soccer players.

The present study is a randomized controlled trial. The subjects of the study were 29 soccer players with three years of experience in soccer clubs. Subjects were randomly divided into experimental (n = 14) and control (n = 15) groups. The experimental group performed soccer-specific SportsMetrics exercises for six weeks. The control group continued normal exercises. For assessment, McGill tests, tuck jumps, and hop tests were used. Data was analysed using a Repeated Analysis Variance Measure (p≤0.05).

The results of the repeated analysis of the variance measure showed a significant difference between the scores of trunk flexion (p = 0.001), trunk extension (p = 0.001), right side plank (p = 0.001), left side plank (p = 0.013), tuck jump score (p = 0.000), hop (p = 0.001), and in the experimental and control groups after six weeks of training.

The results of the present study showed that football-specific sports metric exercises improve core stability and lower limb function. Due to the relationship between core stability and lower extremity function and injuries, especially ACL rupture, to prevent injury and improve the performance of soccer players, it is recommended to use a football-specific injury prevention training protocol.

Article Received on: 2014. 6. 21 Article Accepted on: 2014. 10. 31ABSTRACT The most common knee ligament injuries is the Anterior Aruciate Ligament tear. In addition to the high cost of treatment، damage causes loss of sports participation، creation of secondary damage and mental problems in athletes. Accordingly، prevention of ACL injuries has been given top priority in most Studies. The purpose of this study was to investigate the effect of ACL intervention programs on improvement of neuromuscular deficiencies and reducing the incidence of ACL injury. Searching in specific scientific citations PubMed Medline و Science Direct was carried out for relevant articles with the subject coverage of «Intervention Program»، «ACL Injuries»، «Neuromuscular Deficiencies» during 1996-2013. Some intervention programs (such as Sportsmetrics، PEP، KIPP، FIFA +11) resulted in a significant reduction in the rate of ACL injuries in both male and female athletes especially in individuals less than 18 ages. The result of landing force was controversial، but most of the studies have reported the reduction in hip and knee moment. Increased knee and hip flexion angles were reported in most studies، Changes and improvements over time in various activities، was different. Most studies were reported the improvement of the lower extremities in coronal plan during jump landing tasks. Improving lower extremity muscle strength following training for the hamstring، quadriceps، hamstrings ratio to the quadriceps and early onset of hamstring activity and decreased onset of quadriceps were reported. Selection of appropriate ACL intervention program according to age، sport، and personal characteristic for improving neuromuscular index (corrected hamstring and quadriceps muscle activation patterns) improvement of the biomechanics of movement (landing softer with increased knee and hip flexion and decreased knee Valgus) improving landing pattern and reduction in ACL injury rates are effective.

In addition to high cost of treatment, anterior cruciate ligament tear leads to lesser participation in sports, secondary injury and mental problems. Therefore, prevention of ACL injury in athletes is a top priority in many studies. The aim of this study was to conduct a review over screening tests for neuromuscular imbalance causing non-contact ACL injuries. Scientific citations search engines such as PubMed, Medline, and ScienceDirect were looked for relevant articles using the following keywords: "Screening Test", "Neuromuscular Imbalance" and "Non-Contact ACL Injury" during the previous two decades. Hop tests have high reliability and there is a statistically significant correlation between lower extremity symmetry index of this test and isokinetic knee extensor strength. Static and dynamic balance tests have high reliability and validity and their results have correlation with ACL injury. Both double-leg squat test and single leg squat test are used to assess poor neuromuscular control of the trunk, dynamic flexibility, strength of hip, and balance. Modified Landing Error Scoring System Tests are used to identify movement patterns that increase the risk of non-contact ACL injury. In order to identify the most common neuromuscular imbalance related to ACL injuries, we used tuck jump test. Video drop-jump screening test was used to assess valgus alignment in knee. Familiarity with reliable and valid screening tests related to non- contact ACL injuries will be of benefit to researchers specialized in ACL for prevention of injuries. They will be able to select appropriate tests to identify neuromuscular imbalance in people at risk of ACL injury. Therefore, researchers can provide more specific corrective exercise programs.
