The instep kick technique is one of
the important aspect of a soccer
• 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
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
• 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

compared to the others.
Besides, the follow through

longest compared to the others.
The graphs also show that the
sequence of instep kick is

the last is foot.

• 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
• 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.
• 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
