The aim of this report is to analyse my overhand volleyball serve from a biomechanical perspective and compare it to an elite athlete’s overhand volleyball serve. Biomechanics is the sport science field that applies the laws of mechanics and physics to human performance, in order to gain a greater understanding of performance in athletic events through modelling, simulation and measurement. It is also necessary to have a good understanding of the application of physics to sport. In volleyball the applications of summation of forces, projectile motion and balance and stability have a major influence on the success and accuracy of an overhead serve. Biomechanics is the study of the law related to the movements of pattern of the human body. The …show more content…
(Reference) It doesn’t matter whether the volleyball is being set, served, or passed, it moves both up and forward. This is influenced by the downward pull of gravity and horizontal motion, which is known as projectile motion. The volleyball serve follows a parabolic trajectory, and without air resistance, the volleyball would travel along a parabola, but since there is air resistance, the volleyball travels along a shorter path. (Reference) there are 3 factor that can increase your volleyball serve however if not performed correctly can affect the serve. These 3 are height of release (the higher the better), speed of release (the faster the better) and angle of release (45° for optimum distance). The higher the height of release, the better but it is better because it means the ball travel lower which means the ball is not in the air for long which is harder for the opposition. Generally, the greater the speed of release, the greater the distance gained, the speed of release can improve because it will be more challenging to return. The angle of release improves the accuracy of the shot, which can also make the serve harder to …show more content…
Balance is your body’s ability to stabilize itself during movements that require a shift of your centre of gravity. An athlete's centre of gravity is the exact middle of the body around which it can rotate freely in any direction and where the weight balanced on all opposite sides. It exists at a point along the midline of the body at about 55% of the athlete's height (Reference.) During a volleyball serve, it is easy to see where good balance would be essential, if your stance is off then that will lead to the toss being wrong and the athlete won’t have correct contact with the ball. To increase balance and stability one can do this by standing with their legs apart lowering themselves in a half squat position at the knees. By lowering the centre of gravity it will ensure and increase stability level. When an athlete’s centre of gravity is over their base of support adequate stability is achieved. In volleyball during a dig a player will stand with a split stance and lunge to the ball which allows them to perform an effective dig. If an athlete was to reach their arms out and not move their feet under their
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.
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.
Lacrosse is a team sport that originated in the St. Lawrence Valley area, around 1546. It is played with a small rubber ball, a long stick with a sort of basket at the end, and padding (it is a contact sport). The objective of the game is to shoot the ball into the other team’s goal, using the stick to pass, cradle and shoot. At first, the game was played on a distance of even several miles, and anywhere between 100 and 100000 players in a single game. The teams are now composed of ten players each, 3 of them are offense, 3 defense, 3 midfielders, that can go anywhere on the field, and one goalie, which is the heart of the team. In this essay I will focus on the physics that stand behind lacrosse, and how companies that make lacrosse gear use our knowledge and understanding of forces to make padding and helmets that are safer, and sticks that are made for different kinds of play styles (contact defense, precision, fast offense…).
Bocce ball is a great way to demonstrate the complex wonders of Newton’s three laws in a simple and understandable way. Bocce ball, which was first documented in the year 5200 B.C., is a sport that was first popularized during the roman empire. It wasn’t more than just a leisurely activity until the game found its way back into Italy, once the Roman empire collapsed. Bocce ball was steadily rising and falling in popularity, until a major resurgence in 1896, when it was admitted an olympic sport, and has been part of the summer olympics ever since. Bocce has really become such a widespread sport because you can participate no matter how old, what your race is, or what gender you are. All you need to do is roll a ball. America seemed very separated from the game until a sweep of popularity in California in 1989. Today there is said to be 25,000,000 bocce ball players in the United States. Many aspects of the game of Bocce ball can be relatable to the simple concepts of Newton’s original three laws, from the balls hitting each other (Newton’s third law), to throwing balls harder to increase the force and then slowing down (Newton’s first and second laws). Throughout this essay, I will not only explain what each of Newton’s three laws mean, but provide a real life example of how it could relate to the game of bocce ball.
Newton’s First Law of Motion, inertia, says that an object at rest will remain at rest and an object in motion will remain in motion will remain in motion unless acted upon by an unbalanced force. The ball will not move forward until the server hits it into play and it will not stop until it hits the net or the ground. The second part of the law is momentum where an object in motion will stay in the motion of a straight line with a constant speed unless acted upon by an unbalanced force. The ball will continue to move in a straight line or an arc until a player blocks the ball from traveling any farther. Newton’s Second Law, force, states that force equals mass times acceleration (F=ma). For volleyball, the more force applied to the ball, the further it will go. This is very important in volleyball because the players need to have the perfect amount of force on the ball to get it over the net but keeping it in bounds. Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction. The player hits the ball with a certain amount of force, the ball hits the player’s hand with the same amount of force. In volleyball, the player’s upward motion pushes the ball up, where the opposite reaction is the downward motion of the player’s arm after hitting the ball
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.
The goal of this lesson is for my students to understand the fundamentals of completing a successful bump, set, spike, and underhand serve. These aspects will be important when working with their teammates in a positive manner to complete these tasks and use these components to be successful in game play.

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).
Speed gives a tennis player many advantages. Firstly, your reaction speed is really important too react to a ball being play to your side of the net. In tennis you have too respond really quick to be able to get too the ball on time one tip is to stand on your toes so that you as a player can respond quicker. Furthermore, you need it too move your body around the court. Moreover, the quicker your brain responds to your body the more time you have to run towards the ball. Lastly, speed is crucial in tennis because it makes a player react quicker and be able to hit the ball back easier using there speed to get to the ball on
The main aim was to see if scapula-stabilising exercises could influence the velocity and accuracy of the tennis serve. This experiment focused on recreational tennis players due to limited research in this area of tennis.
A timeless sport filled with -- rapid movements, sweat, anxiety, and team cheering -- volleyball is a sport that many underestimate. There are countless people that say “Volleyball is a girl sport” or “volleyball is not even that hard”. Also you may come across an egotistical varsity football team that refuse to attend any volleyball games, because they are mad that varsity volleyball made it to state championships and they did not. However, volleyball is a sport that requires intense drills, training, and a strong team bond. For instance if you do not dive right when hitting the floor you can seriously injure yourself. I have had torn a ligament in my shoulder diving for the ball, because as a volleyball player you are taught to always chase after a ball even if it means running into a wall. But the best and the greatest experience of all time is when it is a game day, or even better yet the last game that can determine your title in Norcal Championships. Norcal Championship finals is the game that all 14 teams strive for during the
To work on the athlete balance stabilization, a few exercises can be implemented into their training program. Some exercises consist of single-leg balance progression, single-leg balance reach progression, and single-leg balance with dynamic movement progression. These exercises can help assist in the sensitization of muscles spindles leading to improvements in neuromuscular efficiency (Clark, pg. 216).
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.
5)Serving is a very important element of volleyball. A server who can serve the ball reliably and skillfully will help his or her team far more than will a player who, for instance, is inconsistent with their serving. There are a variety of serves that are employed in competitive volleyball, from "floaters" that seem to shimmy and shake on their way over the net to hard-driven jump serves.
