Six university soccer players were selected for a correlational and comparative study. The correlation between squat jump height and 10-metre sprints, 30-metre sprints, arrowhead agility test, static balance test and velocity ofball during instep kickwereinvestigated. The comparative study involved comparisons between ball velocityandbetween the muscle activity of vastus lateralis, rectus femoris, biceps femoris and tibialis anterior of kicking limb and supporting limbduring instep soccer kick from 0-degree, 45-degree and 60-degree angle ofapproachfrom the target with the dominant limb and non-dominant limb. A significant association was found between squat jump height and 10-metre sprints (r = -0.93, p = 0.007) and 30-metre sprints (r = -0.88, p = 0.021). Also, significantly greater ball velocities were attained from 45-degree angle of approach with the dominant limb(¿c = 7.49, p = 0.010, partial 37.50, p = 0.002, partial řj= = 0.88). Greater muscle activity was found in tibialis anterior of kicking limb(H Lø=fj: = 0.60)as well as non-dominant limb(FLiD;;L5,1.03= 6.52, p = 0.015, partial ·}- = 0.57) when the dominant limbwas used for instep kick and in rectus femoris of supporting limb(e LC= 5.536, p = 0.024, partial ij - = 0.52) when non-dominant limbwas used from 0-degree approach.
