  • THE BIOMECHANICS OF INSTEP KICK IN SOCCER LAB 5 GROUP 2 GROUP MEMBERS: NAME MATRIC NO. MOHD ISYAMUDDIN BIN JUMAAT D20101039366 MUHAMMAD HAFIZ BIN IBRAHIM D20101039282 MOHAMMAD SHAHNUR BIN MOHD SHAH D20101039379 NUR HEIDIYATUN BINTI MOHD SALLEH D20101039387
  • INTRODUCTION • The instep kick technique is one of the important aspect of a soccer player. • Instep kicking is related to higher ball speed and less knee and hip rotation in the coronal and the transverse plane compared with other kicks. (Kellis & Katis, 2010) • Success of an instep soccer kick also depends on various general factors such as:– the distance of the kick from the goal, – the air resistance, – the technique of the main kick which is best described using biomechanical analysis. (Kellis & Katis, 2010)
  • Instep Kick Sequence Motion In Real Subject Ball approach Planting one foot at the side of the ball with kicking foot extended to the back The swing through of the kicking foot to kick the ball with the instep of the foot Follow through
  • AIM • This study is conducted to investigate the factors affecting the efficiency of a kick using an instep kick, that is:- The last stride length. - The effective angle of thigh flexion and extension before kicking. - Relationship of the velocity between the body joints.

  • Velocity 5 Point of Instep Kick The graphs beside showing the velocity of shoulder, hip, knee, ankle and foot. Subject 1 The approach phase of Subject 3 take the shortest time compared to the others. Besides, the follow through phase for subject 3 is the longest compared to the others. Subject 2 The graphs also show that the sequence of instep kick is shoulder, hip, knee, ankle and the last is foot. Subject 3 Graph 3. The velocity relationship between joints

  • DISCUSSION • Last Stride Length - From the results shown, subject 3 made a long last stride length (135cm) which improves the accuracy of instep kick. (Refer table 2) - While the last stride length of the other 2 subject is in between 133cm and 120cm. - Stoner and Ben-Sira (1981) reported that the longer last stride length among the professional player in between 1.69m – 1.59m. - Based on the results, it is proven that the higher last stride length will increase accuracy.
  • • Angel Extension of the thigh - In this research, subject 1 extended his thigh at 108 degrees, subject 2 at 90 degrees and the subject 3 at 113 degrees for their largest angle of thigh extension. ( Refer Table 1) - Subject 3 had a biggest thigh extension angle while backswing compared to subject 2 and 1. - The higher thigh angle while backswing with higher angle of leg extension is better because it can generate more power in kicking and increase the distance of ball reach and accuracy (Linthorne & Patel, 2010). The study found that the best thigh extension angle is >100 degree.
  • • Angle Knee Flexion - In this research, we found that the minimum angle of knee flexion for subject 1 is 82°, subject 2 is 118° and subject 3 is 72° degree. Subject 3 got the smaller angle compared to the subject 1 and 2 in maximum knee flexion angle. (Refer Table 2) - The smaller the knee flexion angle will produce more force while kicking and will influence the speed of the ball (Linthorne & Patel, 2010). In this study provide that the best knee flexion angle is <100 degree.
  • • Velocity of the Joint - Based on the APAS results shown, subject 3 had the fastest joint velocity except for the shoulder velocity. (Refer Table 3) - For the summation of forces, higher velocity of joint will produce and provide higher velocity on the next joint.
  • CONCLUSION • The higher the distance of last stride length in range 1.35m – 1.69m will generate more velocity as well as momentum to produce high force and power when kicking the ball (Stoner and Ben-Sira, 1981).
  • • This study showed that the bigger thigh extension (120° – 100°) the smaller angle of knee flexion (40° – 80°) while kicking will generate more force and power. • This is because it can generate more power in kicking and increase the distance of ball reach and accuracy. (Linthorne & Patel, 2010).
  • • The fastest velocity of the segment will generate more power in the summation force theory.
