How The Ball With Your Foot

* The bending of the knees and the use of the leg muscle groups to perform the skill.

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

"The soccer ball's kinetic energy decreases as that energy is changed into sound energy and heat… In this case, the kinetic energy is changed into sound energy.”

Punting a football can be intensively and precisely explained through the study of structural kinesiology. Punting is a skill that is often referred to as kicking. It is performed by releasing the ball from the hands and kicking the ball before it strikes the ground. Punting is an action that takes place in the sagittal plane around the frontal axis. The joints involved are the: atlantooccipital (cervical), intervertebral (lumbar), scapulothroracic (shoulder girdle) glenohumeral (shoulder) humeroulnar (elbow) radiocarpal (wrist) metacarpophalangeal and interphalangeal (fingers) acetabularfemoral (hip), tibiofemoral (knee), talocrural (ankle) and the metatarsophalangeal and interphalangeal (great and

The physics involved in soccer includes friction, torque, center of gravity, Magnus Effect and Newton’s three laws of motion. The physics of soccer comes from three main parts of physics which is velocity, acceleration, and displacement. Velocity is shown in soccer with the speed and direction of the soccer ball when it is hit or kicked. Acceleration is shown in soccer when the ball changes velocity when it is hit or kicked. Displacement is the change in position of the soccer ball.

Biomechanics is the study concerned with the internal and external forces acting on the human body and the effects produced by these forces (BrianMac Sports Coach, 2014). The purpose of this report is to biomechanically analyse a partner’s Oztag grubber kick by comparing the kick to that of a skilled performer. Oztag is a popular Australian sport, played by many. The grubber kick is a short kick ground, used as an attacking ploy when the player is near the try line. This report will focus on the force summation, Newton’s Laws, levers and balance in relation to the performance of my partner’s kick and will suggest recommendations to improve the success of her kick.

Biomechanical Principles Applied to the Soccer Kick Principal One: Stability increases when there is a low centre of mass, when there is a wide base of support, the centre of gravity is within the base of support and there is a large mass. Unstable balance occurs when an athlete needs to be balanced but ready to move quickly and become unstable. The player is unstable as she flexes her hips over the ball during the backswing/recovery. She is slightly balancing herself as she extends her hip and puts her arms outward on her sides so that she will not completely fall over.

That objective of a soccer game is to score goals by either kicking or heading the ball into the opponent's goal. A soccer kick is the main offensive action during the game since, the team with the most shots on target has a better chance to score and win the game. It is important to know that before a shot is taken, the placement of the supporting leg and the kicking leg, and the body's balance before and during the foot's contact with the ball, are some of the key factors that the kicker has to look into, to have a successful shot. The accuracy of a kick all depends on the contact between the kicker’s foot and the ball, and kicking the ball in a certain area affects how it travels in the air. An example would be kicking the ball in the

The first and maybe the most important step is where you make contact with the ball and where on your foot you strike the ball. The part of your foot that you should kick the ball with is the frontal part of your instep and you need to kick the ball on the outside edge and in the middle of the y-axis.

A study led by Berry (2005) observed the place kicks for the 1998 NFL season. He considered the kick taker, the distance of the kick being taken, the result of the take kick and the accuracy of the kick in measuring goal scoring abilities. Furthermore, Berry mentioned in his study that the NFL presently only rank the kick takers by their successful percentage of kicks taken rather than an overall measure of their kicking performance which should include the distance of the kick. If we look at the parameters included and the parameters excluded there is a potential difference to the accuracy measurement of Berry’s goal kicking model. He himself stated that he excluded the wind, rain, snow and blocked kicks. Another study conducted in the NFL revealed

Phase 3 commences with the athlete in the air. He or she then slightly rotates the upper torso, with the dominant side extending backwards in preparation for the forward swing. The elbow must be kept flexed, the wrist in a slightly supinated position, and the palm of the hand as flat as possible. Once the spiker reaches peak position, the shoulder and arm begin forward motion in an attempt to make contact with the ball. Phase 3 is concluded after the ball has left the palm and the athlete returns to neutral body position, in preparation for the landing. Upon reaching neutral position, phase 4 initiates. Phase 4 is the final phase of the volleyball spike, in which

Magnus effect plays a huge role in justifying the behavior of a soccer ball in flight. The

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

Figure 1 and Figure 2 are action shots of the athlete doing the set activity. The first image according to Carr (1936:152) [is the] Preparatory Movements and mental set up [stage, this is] the motions and mental processes that your athlete goes through when setting up and getting ready to perform. Through each of the stages, which are correctly stated in the appendices, they show that the athlete attacks the ball at a slant to give themselves power and speed to get accuracy for the shot. On your last stride, you want your non-kicking foot to be "planted" right next to the ball. As soon as your non-kicking foot hits the ground, your kicking leg should bend at the knee so that you heel almost touches your behind. (Phyre, 2009). Here is a brief description of how the athlete should be striking the ball. From the screenshots that are provided, the athlete runs up to the ball and they do plant their leg to the side of the ball and use their right leg to extend backwards at a 109° angle. According to Brancazio(1985:403) the ‘kicker dilemma’ is that he must chose a laughing angle, somewhere between extremes of 45° and 90°. This is an improvement for the athlete as their angle reached 109° so therefore the athlete should be aware how to improve this because it could save them an injury. Hip flexion is the primary hip movement in straight ahead kicks because the player swings his leg straight back while

To perform this action efficiently, to achieve faster speed and better accuracy upon release, the player must performing this action by rotating the trunk away from the player at which the ball is being thrown to and become slightly hyperextended. It is here that the axial skeleton comes into action with the vertebrate in particular whilst the eternal oblique’s and rectus abdominals extend and the erector spinae contract. The legs are also spread with the right hip laterally rotated and extended and the left hip is left in a neutral position underneath the athlete. By creating this position it maintains equilibrium and control of the upper body (figure 5: A). The left knee is flexed in preparation for a forceful extension during the force-producing phase through the contacting of the hamstring and lengthening of the quadriceps (figure 5:A). During this, the arm abducts whilst the elbow joint (hinge joint) flexes to a 90 degree angle as the bicep connected to the humorous is contracting (agonist) and the triceps and lengthening (antagonist). The throwing arm then goes from shoulder lateral rotation and lower arm supination to shoulder medial rotation and lower arm is pronated, supplemented by elbow extension. The trunk then rotates again to the target, the back is then hyperextended with slight lateral flexion, the arm comes forward, the wrist is flexed and the wrist snaps down (plantar
