and stability allowing the knee joint to slightly rotate the body before and while releasing the ball and lastly the tarsals,metatarsal and phalanges (comprise the bones of the foot to allow

In order for maximum force to be generated, a tennis player needs a good stable base from where they can begin the movement. The tennis serve begins with flexion of the knee joint caused by the hamstrings. Then comes extension of the knees as well as hip flexion to start the movement - both of these movements are initiated by the quadriceps. The Erector Spinae muscle causes trunk extension to allow the abdominals to fully flex the trunk and generate the force that is then transferred to the upper body. The deltoids and pectorals major are used to flex the shoulder. These muscles are used to accelerate the whole arm while also stabilising the shoulder. Once the arm has begun to accelerate towards the ball, the tricep brachii is then used to

Tennis serve is the shot that starts off the point. It is normally instigated by pitching the ball into the air and thumping it into the diagonally opposite service box exclusive of touching the net. This act is attained underhand or overhead. It is the only attempt where a player takes his time to position up, instead of reacting to an opponent’s shot. In doing this, high percentages of the efforts are normally exerted at the upper extremity of the body, while the rest at the lower extremity of the body. the serves comes in five main types of which includes; cannonball or flat serve, topspin-slice serve, slice serve, American twist serve and the topspin serve. The paper will focus on the some of the types of the serves and the ways in which the upper extremity are involved in the game. With this, it will look at the movements that occur at each of the upper extremity together with the muscles that are in use at the joints.

In the tennis serve Newton’s third law of motion is applied as the player performs a leg drive to the court to generate an equal and opposite reaction (Ackland, Elliott & Bloomfield, 2009, pp 314).

Without the movement of the lower body, a shot would end up anywhere but the back of the net. The lower body helps a player produce a straight shot so the ball winds up leaving the stick in the direction that the shooter intended.

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.

II.     As well as using your lower body, it is also essential to use your upper body in order to maximize the chance to score.

As the tennis server prepares to swing their racket in the serve, they bend their knees, which stores elastic potential energy in their legs. This elastic potential energy is also referred to as strain energy. As the legs are bent the muscles and tendons are stretched in a way that stores this strain energy(biochmechanics). The greater the bend and stretching in the legs, the greater the power generated as the legs are extended(biomechanics). As the tennis player extends their legs this elastic potential energy is converted to kinetic energy and a ground reaction force is generated. This ground reaction force can also be called normal force. As the player extends their legs the tennis court ground in contact with their feet is compressed

It embodies the basic biomechanics principles that most players go through when they are shooting a jump shot. Each player’s could be evaluated differently. This was simply a summary of a natural jump shooter. Biomechanics can be used to assess a player’s ability to shoot accurately and consistently. This analysis did not focus on what a correct shooting form is.

Playing tennis involves more muscles than simply your arm and wrists. It involves a series of complex movements that start with your feet and ends up swinging a tennis racket. It requires a honed and well-trained muscular system to perform with the required power and speed needed. The muscular system is one of the most important systems involved in the sport of tennis. The muscular system is the tissue of fibres around your bones. This is a main part of tennis because specifically these muscles will put force on the bones and pull them. This will result in the tennis player getting more power behind there hit and also helps the play with moving around the court in a quicker pace.

The next stage of the instep kick in soccer is the swing limb loading stage or the wind up of the kicking leg. This is the part of them movement that produces power and force essentially transferring over into the next phase. This part of the movement involves a concentric contraction of the gluteus maximus and hamstrings that results in hip extension making the hip rotate internally due to the concentric contraction of the gluteus medias. Knee flexion is the main

When the game is on the line, these are the guys that you would want to play in the team you belong in or you are rooting for (for the fans who only watch the games). These athletes have undergone rigorous training in order to attain the fame that they have today but behind all these is physics. This paper would like to investigate therefore the physics behind accurate shooting of the basketball that makes these athletes so famous around the world. II. BASKETBALL TERMINOLOGIES

This exhilarating sport consists of indoor tournaments and beach tournaments. Serving is the most powerful aspects of the game and requires training. This power point will begin to breakdown the different components of the volleyball serve by discussing the key biomechanical principles involved. Looking at the principles including, force and how the height plays a role in the ability to apply force to the ball, motion and the factors athletes need to maximise accuracy and accuracy and the different options and drills that enable an improved serve. Linking biomechanics procedures and volleyball includes the dynamics of the rules or equipment used throughout the game of volleyball.

There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.
