Primary purpose of the skill
The backhand stroke is one of the fundamental strokes of tennis. It is used frequently during all stages of a tennis match or a practice, and is therefore a very important skill for a tennis player to master. The motion’s objective is to hit the ball over the net and inside the lines of the opponent’s side of the court. For the player to achieve this requires both high raquet speed, good eye to hand cordination and presition in placing the ball. Hence, delivering maximum speed to the ball, and at the same time, placing it with accuracy are mayor skills that a tennis player seeks do always improve. The force of impact, wich results in ball speed, is detirmined by the speed of the racket at the moment of contact with the ball, and maximum velocity can be obtained only when maximum distance is used for accelerating. That can be desribed as the backswing. The function of the backswing is to provide a longer path or distance for the racket to travel and to buid up
The only joints that have primarily roles are the knee joints, who performs extension. This action is executed by the Rectus Femoris in a concentric contraction in a sagittal plane and bilateral axis. In the upper body however motion is conducted in multiple joints. Starting with flexion of the elbows, the Biceps Brachii, assisted by Brachioradialis, contracts concentrically in a sagittal plane and bilateral axis. The shoulder joints both continue their motion from the previous phase, internal and external rotation, as the arms hit the ball and continues toward their ending position resting at the right shoulder. Last but not least are the wrist joints. At the same time as the right wrist is hyperextending, the left wrist performs radial deviation. Both of these movements are caused by the Extensor Carpi Radialis Longus and the Extensor Carpi Brevis in a concentric

Most amateur golfers believe that impact on the ball is the only key factor for hitting straighter and farther by swinging harder and faster, forgetting important facets in basics of the swing. There are multiple parts of the swing that involve biomechanics however; some key points are set-up, backswing, downswing, follow-through, and ground reaction force (GFR). To focus primarily only on one point of the swing to fix all problems is an obscure way to view the s...
Tennis is a game in which two players or a pair of players use rackets to hit a ball over a net on a rectangular court. The history and origin of tennis was said to be started many years ago approximately the 12th century by European Monks. Before tennis got its name the game was called Paume basically meaning the ball was hit by the palm of the hand instead of a racket. In the earlier years the game was played in a monastery courtyard. The game used walls and sloped roofs as part of the court. Eventually after playing tennis for a long time with their palms they transitioned over to gloves. The gloves were made out of leather which made playing tennis more comfortable. The glove was later replaced with an adaptive handle which made hitting
The innovations in the material of the tennis racquet — the strings and the frame — have changed tennis throughout the years; thus, fundamentally changing the game by allowing players to hit with more power, spin, and racquet speed. Many star professional tennis players in the past and present use new technology to help take their game to new levels. The change from a wooden racquet to a carbon-fiber tennis racquet and the change from cow gut strings to non-gut synthetic strings have changed the way tennis is played.
Since this is a flexion movement, the posterior muscles of the knee performed this action. They include:
Joints which include rotation is the shoulder joint and the hip joint, this allows us to move the bones connecting to that joint in a wide range of directions. This type of rotation can also be broken down into two types of rotation: medial and lateral (internal and external). Ball and socket, condyloid and plane joints allow this type of movement. Internal rotation of the arm is when the arm is flexed but it moves towards the centre (midline) of the body. However external rotation of the arm is when the arm is flexed, but it moves away from the midline of the
The motor active domain is like the frame of a puzzle when one has assembled the outside pieces first. The variables under this domain represent the individual pieces of the frame. At first look, since the perimeter of the frame is large, it appears as though it makes up a large part of the puzzle, but in fact, the frame is made up of only a small number of pieces. This is also true in a performance: the motor active skills appear to be the greatest factors, but the truth is, there is only so much one can improve physically. Practice improves skills and creates a technique, or a particular way of executing a task. In tennis, that is closely linked to the strategy, or plan, of a player’s game-style. For example, I’m more of an offensive player who likes to make the opponent run from corner to corner and then, at the right time, hit a powerful, well-placed shot that the opponent cannot get to; in simpler terms...
The knee joint is extended when in the standing position, to stabilize this joint the biceps femoris, semi-mebranosus, semi-tendonosus (hamstrings) and the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis (quadriceps) co-contract isometrically.
There is moving joints where it allows a person to either bend or twist. However, some of the joints allow us to move in freely motion while others only allow little movement at all. There are two kinds of joints. One of the joints is called hinge joint which tolerates movements back and forth in the single direction or it connects the upper part of the body, humerus, ulna, and the lower part. A ball and socket joint is also another joint that allows for a lot of movement in all directions possible like a ball in a socket (Marieb 259). Shoulders and hips are the example of the ball and socket joint. The muscles are connected to bones by tendons, bones are connected to each other by other bones itself. Also, the bones are held together at the joint by ligaments. The ligament is like a band of tissue or the white part of the muscle. Between the joints of a bone, rubbery tissue can be found and called cartilage. Cartilage is like the cushion for the bone in which acts as a shock
Quite a lot of people have witnessed a tennis game, whether in person or on TV. Although often depicted by foreigners of the game as being “an easy sport”, Tennis on the contrary, requires quite a bit of technique and skill to even begin the game. Every point in this game begins with a serve, so if anyone was to hold their own on the court, they would at least be required to begin by learning to serve. In this document, I will be explaining the different techniques and postures necessary to successfully complete a serve and hopefully ace your opponent.
Imagine playing a six hour tennis match! Well, the longest match ever played was six hours long; played by Vicki Nelson and Jean Hepner in 1984. (Seminara, 2009) The scoring for tennis is kind of difficult if not familiar of how the game is played. The way the scoring goes is “luv, 15, 30, 40, or deuce if the score is 40-40. If it is 30-30, then it is said like “30 all”. In order to win, the game is played best of three matches. The winner must win by two games. In my study I will be getting the speeds of a group of tennis girls hitting the tennis balls. My hypothesis is that the more experience you have in tennis, the fast you should be able to hit. Because there are so many varieties of elements in tennis, one should consider the difference in racquets, tennis shoes, courts, and balls

Tennis is a sport that many people love to play. It is not the hardest sport in the world to learn. When playing against someone, it is called a match. Tennis can be played one on one or a doubles match. The main object of the game is to hit the ball over the net, inside of the lines so that the opponent can't get to it. There are two lines about two feet parallel to each other that outline the court. In a singles match, the inner line is the out of bound line, while the outer line is out of bounds in a doubles match. If you want to play, take a look at my two favorite tennis players because they are masters at serving and scoring, a few key aspects of the game.
A good service in volleyball is important to a winning strategy. Either an effective serve will not be returned, leading to a point, or it will be returned with minimal strength, providing the serving team with the advantage. One aim of a good serve is to provide the receivers with little time as possible to react. Forces and angles are the two main factors at play when relating volleyball with math (Papageōrgiou & Spitzley, 2003). In short, in order to relate volleyball with math, the force needed to make the ball move a certain height or distance, the angle required to make the ball over the net, and the arrangement of players, such that less players cover more ground need to be well illustrated. This paper connects the concept of mathematics to volleyball, explaining various models of a served volleyball in details.
Hearing the loud “thump” as the ball hits the racket is extremely satisfying, especially if your life now revolves around this fast-paced and exhilarating sport. Tennis is an outdoor game played by two individuals or pairs of players on a clay or grass court that’s divided by a low net. Each game is played with tennis rackets and small, yellow elastic balls. Tennis was first introduced in Wales and the United Kingdom in 1873 by “Major Walter Wingfield” (tennistheme.com). While most sports are easy to pick up, tennis takes extreme dedication to learn how to play the game, to perfect the amount of technique it takes, as well as its great impact on one’s personal life.
