Movement Analysis For An Instep Kick

balance of the body also flexion on the back leg when the ball is being released ending in a plantar flexion position .

On the downward phase flexion occurs at the knee, stopping at about 90 °. Both quadriceps, acting as the agonist to flex the knee, and hamstrings, which mainly stabilizes the knee, act as an antagonistic pair and co-contract eccentrically to allow flexion. The hamstring is also acting as the synergist for the hip joint (Tortora and Derrickson, 2009). The Sartorius acts as the synergist and also contracts eccentrically to cause flexion at the knee (Wynsberghe et al., 1995).

The way you position your body could depend on how you kick. If you are in a slouchy stance, then you won’t get a good kick. But, if you stand in an athletic stance then you can get the most out of your kick. An athletic stance your knees are slightly bent, your resting on the balls of your feet, and your body weight is centered at your hips. Place the foot that your are not kicking with skightly in front of the kicking foot. Toes on both feet should be facing toward the place of contact.

“The analysis of movement provides an athlete with optimal development as well as minimising the risk of developing injuries through the incorrect execution of a movement” (Ackland, Elliott & Bloomfield, 2009, p 301).

Velocity is how fast you’re moving, when you kick the ball it’s putting Velocity on it. The more force you put on the ball the more speed it has. Soccer players need to get the ball as fast they can, so they need to increase the rate they change their position at.

Figure 1.6, shows as subject A sprints, his legs cross over the midline of his body. This causes the body to waste energy moving side to side horizontally rather than forwardly in a straight line (Burkett,

The roundhouse kick, a multiplanar skill, starts with the kicking leg traveling in an arc towards the front with the knee in a chambered position (Pearson, 1997). The knee is extended in a snapping movement, striking the opponent with the top of the foot. One's goal would be to make front torso contact with the kick, while avoiding leaving one's self open to a counter strike.

To kick the ball, take a run up on the diagonal and place your weaker foot right next to the

The leg action in running is one that takes place in a sagittal plane about a frontal axis and involves the hip, knee and ankle joints.

This is trailed by pronation of the foot with the objective that it can help suit the ground structure. The lower leg goes into flexion allowing the knee to progress, and the body takes after. The heel raises, and the foot supinates transforming into an inflexible lever that aides in the pushing movement that at last shuts with the toe-off.

As you observe someone walk the hip, knee, and ankle performs different actions during the heel strike phase, flat foot phase/stance phase, toe off phase and swing phase. If you start with you right leg during the heel strike phase the hip is flexed, the knee is extended and the ankle performs dorsiflexion. Then during the stance phase the hip is slightly extended and the knee is extended and the foot is slightly performs plantar flexion. With your left leg you next begin the toe off phase. The hip is slightly extended, the knee is slightly flexed and the foot performs the action plantar flexion. During the swing with the left foot the hip is flexed, knee is flexed and foot is slightly performing the action plantar flexion. Next the left leg

The power of kicking a ball predominantly comes from the knee straightening. This knee extension, can only happen if the top thigh muscles contract. These muscles are called your quadriceps, that have four individual components; the vastus lateralis, vastus medialis rectus femoris and vastus intermedius. these all join just above the shin therefore being able to lift the lower leg

When there is weakness present at the proximal hip, some of the alterations and compensations to the back squat and step-up and step-down exercise may include pronation of the foot and “buckling” of the knee into an internally rotated state when at the bottom of the movement.26 Should a weakness in the gluteus medius be noticed, the step-down exercise can be utilized to increase the muscular strength of the gluteus medius, increase ankle range of motion, and in turn decrease the amount of internal rotation of the femur as well as the amount of foot pronation due to weak intrinsic foot musculature. When performing the step-down exercise, the supported gluteus medius is responsible for maintaining proper hip balance to the unsupported hip. As seen in Figure 13, the hips are balanced and aligned. Figure 14 gives a clear example of an athlete revealing improper technique due to weak gluteus medius. Another compensation for weak proximal hip musculature can be seen from a lateral view as shown in Figure 14. Altering tilting of the torso is one prime example of a compensation. Another common compensation is to allow the knee to flex beyond the toes. When viewing the step-down exercise from the lateral aspect, the knee should not go beyond the

Many things can be analyzed from the action of performing a Jump Front Kick. Mainly characteristics that varied over time were the best to analyze. Subjectively (those based on personal experience,) the eye sight, balance and muscle engagement were most apparent. Objectively (those not based on personal experience,) the height, inhabited space and center of gravity were observable. Analysis performed would later influence the creation of sketch models that showcased specific characteristics.

Once the subject had completed the warm up session, they were then instructed to stand on the Biodex Balance System (BSS) (Biodex, Shirley, New York, USA), using the leg that they would use to kick a football with. (All of the subjects were dominant using their right foot). They were allowed to flex their dominant knee up to 10° to ensure that the talo-crural joint was mainly targeted during testing. They were also required to maintain an upright posture, and to maintain a comfortable knee angle with the unsupported leg. If the subject were to touch the support railings during the assessment, it would invalidate the results and have to be repeated. Once in position, the platform was unlocked allowing for movement. The subjects were then instructed to adjust their dominant foot's position until they found the position at which they were at the most comfortable and stable. This was done to establish the subject’s ideal foot positioning for testing. The platform was then locked, and subjects were told to maintain their foot position. This position was used for testing, and recorded by investigators. The testing protocol consisted of a single 20 second test using level 8 resistance provided by the BSS. This process was then repeated for the opposite limb.
