Primary Outcome Measures

Name	Time	Method
Return to Sport - return to full play. <br>Participants will be asked to report the date when they returned to full, unhampered training. This date will be reported in terms of days post injury and comparison will be made between treatment and control groups [6 weeks post intervention]

Secondary Outcome Measures

Name	Time	Method
Active Knee Extension (AKE) test <br>Difference in degrees of leg extension between injured and uninjured legs. Analysed using goniometer[3 and 6 weeks post intervention];Straight leg raise (SLR) <br>Difference in degrees of leg extension between injured and uninjured legs. Analysed using goniometer[3 and 6 weeks post intervention];Isometric resistance hamstring contraction at 30 degrees and 90 degrees of knee flexion. <br>Difference in isometric power maintained for 3 seconds between injured and uninjured legs. Analysed using hamstring EFD strength test equipment [3 and 6 weeks post intervention]
