Gender inequality in professional tennis is a real and alarming issue, from the pay gap between mens' and womens' tennis players to the low media coverage of women's professional tennis. This issue even goes as far as how differently tennis commentators discuss and analyze mens tennis as opposed to how they discuss and analyze womens tennis. When commentators discuss men's tennis they solely focus on the skill of the players, but when they discuss women's tennis they place more importance on the appearance of the female players, rather than their skill. This instance of gender inequality in professional tennis is further exacerbated by the differences in advertisements for male tennis players and female tennis players. The advertisements involving male tennis players display their athleticism and tennis abilities, whereas the advertisements including female tennis players are appearance-focused, with the females often wearing little clothing. This is corroborated by the popular belief that focusing on the physical appearance of female athletes is the only way in which generating money from women's professional sports is distinctly possible (Fink, 2015, p. 338). Female professional tennis players train just as hard as the men do, thus the gender inequality that exists in the sport is not necessarily a result of how women perform on the court. It is rather a result of how society perceives women playing in professional sports overall, which the mass media is partially to blame

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

There are three main energy systems used in a game of touch football which consist of the creatine phosphate (ATP PC) system, lactic acid system and the aerobic system. Each system plays a vital role during game play. Every muscle in your body requires energy to perform all movements, and to do this, the energy is produced by the breakdown of a molecule called adenosine triphosphate (ATP). ATP is found in all cells which is a chemical form of muscular activity and performs mostly all functions in the human body. It contains 3 phosphate groups and adenosine. ATP is stored in the muscles and lasts for approximately 10-30 seconds. Carbohydrates, fats and proteins, are all producers of ATP from the food we eat; however Creatine Phosphate is

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).

A normal tennis ball has a rubber core occupied with a gas that is composed of unorganized molecules or atoms that move around freely. Molecules of a gas can effortlessly expand and contract. When the ball hits the ground, the force causes the ball’s bottom surface in, and the gas in the core constricts. The gas then springs up when the ball becomes its usual shape, causing the tennis ball to bounce up.

Stronger legs can allow players to run faster, have more power when they kick the ball, and have better control when shielding and protecting the ball. Soccer players are usually the ones working out their legs at the gym, which can help them to prevent injury ("Soccer Players: Lift with Your Legs!"). Instead of focusing on lower body, tennis uses much more of the player's upper body, although lower body muscles can give the player the advantage of getting to the ball faster. Tennis players need to be strong enough to have sufficient power in hitting the ball. They also need ball control, which can come from being more in control of their upper body. These players will often focus more on free lifting or resistance bands when training (Strength Training For Tennis").

The purpose of this project is to analyze an overhand volleyball serve from a biomechanical perspective. Biomechanics is defined as forces and movements on living systems. It looks at the internal and external forces that act on the body, and the movements that these forces create. By understanding the biomechanical concepts, you can train your body to move with accuracy. It also enables us to develop new skills, correct minor mistakes, develop new equipment design, and improve safety to reduce the risk for injury. The volleyball serve almost looks like a throw-like movement because the joints used extend one after another. The reason behind this is that within the movement, the shoulder extends before the elbow and wrist; the shoulder actually begins to extend while the elbow is still

When absorbing ground reaction forces during physical activity, rather than using the muscular prime movers of the lower extremity, females act on the use of bony configuration and articular cartilage and ligaments to absorb these forces (4). Newton’s third law states that for every action, there is an equal and opposite reaction. In any action of sports whether a soccer player makes a cut on the field, or a basketball player lands from grabbing a rebound, the reaction force is actually greater than an

The external and internal forces acting on the human body and the effects produced by these forces is known as the study of biomechanics, it is a very crucial part in sports as it can help detect inadequacy of any physical technique performed, result in enhancing an athlete’s performance. I will be biomechanically analyzing my own volleyball spike.

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.

Flexion is the movement which decreases the angle between bones at a joint. The knee must be flexed for balance and momentum. This is done by lowering the gluteus maximus as it allows the knee to create this necessary movement. The elbow and wrists also need to be flexed to act on the pressure of the ball. The movement of extension is where the angle between bones at a joint is increased. Examples of this movement in a free throw are straightening the knee as you begin to release the ball and straightening the elbow when the ball is released. This follows with pronation which is when the hand and forearm rotate, making the palm face downwards. For example, when the ball is held by the palm and then is transferred off the palm in an upwards movement. This forces the wrist to flick in a downward

Jahari, Jashwah and I are extremely humbled and thankful for such a generous gift. We are honored to be a part a such a wonderful tennis program. The boys are excited to be selected as scholarship recipients again and they’re both making the most of this opportunity. They’re both working had each week to improve and refine their tennis skills and improve in different areas of their tennis game.

Two different exercise groups were compared to see if velocity and accuracy of the tennis serve improved following a six-week exercise programme. Results of this study did not demonstrate a significant change in velocity and accuracy between pre-test and post-test data. However, the whole-body exercise group did show a significant improvement in velocity compared with the scapular stabilising exercise group. This highlights how the use of the LEX in the kinetic chain of the serve can influence the velocity more than solely
