Abstract

Previous findings have suggested that regular measurements of groin risk factors may propose a preventative measure against injury and have clinical implications in assessment, rehabilitation and return to play criteria. Therefore, the aim of this study was to (1) identify and understand the changes in strength and flexibility of the hip adductor muscles and (2) how the adductor squeeze and bent knee fall out (BKFO) test values vary in different hip positions with increased football match play load. Twenty male university level football players from four different clubs (age = 22.35 ± 1.98 years, height =177.65 ± 5.58cm, body mass = 79 ± 7.45kg) participated in this within subject repeated measures design study. Each participant performed 3 maximal adductor squeeze tests at both 0° and 45° test position along with the BKFO. Adductor squeeze and BKFO values were quantified using a sphygmomanometer and inflexible tape measure respectively. These measures were recorded at all three stages of testing; before (0 minutes), half time (45 minutes) and at full time (90 minutes) of the match. The results displayed a significant effect of time played on hip adductor muscle squeeze testing, F2,38=106.544, p <0.05. There was also a significant effect of angle of hip flexion on adductor muscle squeeze testing, F1,19=68.723, p <0.05. These decreases equated to -17.7% in 0° test position and -19.1% in 45° test position when football match play load increased. Correspondingly, the Friedman test indicated that there were significant differences between the three time groups in the right BKFO, χ22 = 24.603, p = 0.001 and left BKFO, χ22 = 22.464, p = 0.001, (-16.9%). In conclusion, university football players exhibit decreased adductor squeeze test and BKFO values when football match play increases when compared to players’ baseline test values. These findings have implications in assessment, rehabilitation and return to play criteria. Future research should examine a more relative strength measure, draw up more distinct injury thresholds and explore the strength ratios of adductor to abductor as this remains a great risk to injury.
