EMG activity in the kicking motions of soccer
The purpose of this study was to compare the muscle activity of the hip and knee between the soccer full instep and pass kick strikes of the ball. Five former or current professional male soccer players performed three repetitions of both techniques of kicking. Specific comparisons between techniques were made regarding onset, offset and iEMG of the gluteus maximus (GM), rectus femoris (RF), and biceps femoris (BF). Analysis was performed for iEMG for all three muscles during the loading phase (LP), swing phase (SP), ball contact (BC), and follow through. Comparison of the Onset and Offset of the muscles was performed during the SP and the BC phases of the 2 movements. The study showed no statistically significant difference between the muscle activity in the 2 techniques. This study concludes that for the BF, GM, and RF the force and timing of muscle activation is the same between the techniques.
