The effect of functional movement screen and lower extremity training on hamstring/quadriceps ratio in football players

Abstract

Purpose: The aim of this study is to determine the effect of functional movement screen and lower extremity training on hamstring/quadriceps (H/Q) ratio in football players. Material: 11 players from Sivas Belediyespor, affiliated to the Turkish Football Federation, participated in this study. The average age of the players involved in the study was 25.75 +/- 4.45, height averages 178.49 +/- 8.72 cm, and body weight averages 69.83 +/- 6.47 kg. Players who participated in the study had previously suffered a knee area injury. In addition to team training for 8 weeks, extra exercises to strengthen their hamstring and quadriceps muscles were conducted 3 times a week. Isokinetic force tests and Functional Movement Screen (FMS) tests were conducted in the study. Data obtained were evaluated in SPSS package 24 program. Results: There was a significant difference in the total score of FMS at the level of p<0.05. Deep squat 13.5\%, hurdle step 10.49\%, in line lunge 9\%, shoulder mobility 3.44\%, active straight 6.84\%, trunk stability push up 6.84\%, rotatuar stability 14.73\% and FMS total score 17.24\% showed improvement. There was a significant difference in the H/Q ratio between both the right knee and left knee pre-test and post-test at p<0.01 level. The right knee developed at a rate of 600 H/Q at a rate of 17.24\% and the left knee developed at a rate of 600 H/Q. Conclusions: As a result, 8 weeks of extra lower extremity exercises can be said to increase the H/Q ratio of football players. It is also seen that the FMS score has increased. Thus, it is thought that the risk of football players having a sports injury again is reduced.
