Functional Hamstring to Quadriceps Strength Ratio (H:Q) and Hamstrings Injury of Soccer Players: A Qualitative Analysis

Abstract

Background: Soccer players are required to perform explosive and powerful movements as the game is very competitive and intermittent nature. Functional hamstring to quadriceps strength ratio can plays a significant role to perform these movements. The imbalance of this ratio occurs hamstring muscles injury. Current researchers found the clear connection between functional hamstring to quadriceps strength ratio and the non-contact hamstrings injury of soccer players. Objective: The aim of the review study was to analyze the functional strength ratio between hamstrings and quadriceps as a measure of hamstring injury. Method: Researchers collected scientific evidences through electronic online databases; PubMed, Embase, Medline, Google scholar, Web of science, PsycInfo, and critically analyzed the entire relevant article according to the nature of this study. Findings: Nordic hamstring strengthening exercise and FIFA 11+ injury prevention programme may reduce the rate and severity of hamstring muscle injuries and also develop the eccentric strength of hamstrings especially on biceps femoris long head muscle fascicles. Conclusion: Hamstring to quadriceps strength ratio need to be maintaining regularly to overcome hamstrings injury. Progressive and systematic nordic hamstring strengthening exercise can decrease hamstring lesions and reduction of re-injury.
