Swimmers use four different strokes to swim an Individual Medley swimming event. Swimmers propel themselves through the water using four different arm strokes and four different kicks. Each arm stroke has a kick designed to meet the tempo of the swim. We refer to the strokes in the order in which they are performed, the butterfly stroke, the backstroke, the breaststroke, and the freestyle stroke. The four strokes are consistently swum in this order based on the rules that govern competitive swimming.
Butterfly Stroke
The butterfly stroke is the first stroke of the individually medley event. The butterfly stroke takes place at the beginning of the race and requires the swimmer to start from the starting block. The swimmers start consists of a streamlined body position for maximum entry speed and is followed by a two leg, simultaneous kick that begins from the hips in a whip fashion that follows through to the toes. This kick is most like the movement that a dolphin uses to propel them through the water. Because of the similarity of the movement, the kick is called the dolphin kick. The kick is combined with a simultaneous arm pull that starts with the arms stretch out in front of the swimmer. Both arms pull through the water together for maximum power. The arms sweep downwards towards the bottom of the pool creating a 90-degree angle in the elbow. Then the arms sweep past the ribs and end at the hips. The palms are in an upward position to the surface of the water. The power from the stroke lifts the swimmers shoulders to the surface to maximize the opportunity for a breath. Once the head lifts for the breath, the arms thrust forward over the water like the upward thrust of the arms during a jumping jack. During ...

...or the speed of this stroke. Swimmers can choose how many strokes they take before they need to breathe. Each breath is a movement outside of the streamline. Every movement of the body outside of the streamline body position of this stroke can slow the swimmer down.
Narrative
The entire event is four equal distances in which the swimmer completes one of each of the strokes in sequential order. After each stroke, the swimmer must transition to the next stroke using a legal transition designed to allow the swimmer to carry their speed through to the next stroke. Although there are many other individual events that swimmers can compete in, the individual medley is the only event in which only one swimmer does more than one stroke at a time. Swimming the individual medley allows a swimmer to show off their power, technique, endurance and mastery of swimming.
water, curved and smooth and green.'; This seems to illustrate the peacefulness of the situation, almost creating a lazy, calm atmosphere. However, the imagery within “The Swimmer'; is quite opposite. “The Swimmer'; tends to portray a scene of force, as there is no evidence of the peaceful interaction between man and water as found in “Lone Bather.'; Evidence of such force ...

Throughout the story, John Cheever uses the the literary device of symbolism to illustrate the theme of a cyclic human experience that erodes away every day. Throughout the story "The Swimmer," Cheever uses this device to represent a plethora of symbols. For example, the main and initial symbol perceived in everyones minds are the aqua swimming pools. While wasting the day drinking at his neighbors house, he has an epiphany to swim through all the pools on the path back home. Before this however, the main character, Neddy, complains about the days where everyone just moans that they drank too much last night. The day is tedious, and nothing out of the ordinary occurs on the horizon. Neddy's trip turns out to be not much different. For that every pool the stereotypical suburban scrub swims through, he only just goes through a period of time and monotony. These pools are all the same, and when he comes out the other side of one, he isn't even aware of what has just passed. Analyzers of this poem have muttered, “He has been swimming in the Westerhazys' pool. And what does one swim in a pool but repetitious laps? Even the stroke he uses is repetitious” (Blythe & Sweet). This is backed up by Cheever's writing: "He swam a choppy crawl, breathing either with every stroke or every fourth stroke and counting somewhere in the back of his mind the one-two one-two of a flutter kick" (Cheever). Cheever’s intentions along with Blythe and Sweet in these quotes are that nothing is new, everything is the same. For that many can relate to this idea, and for that everyone is a swimmer in their own way. Swimming unvaried strokes in similar pools of lost time and repetition.
Right through the film, Vincent and Anton races in different ways since childhood to adulthood. The really distinct one will be the swimming scenes. With Vincent and Anton, their swimming competitions are held in the ocean, which is a natural place, symbolizing rebirth. Initially, Vincent loses the race because of the health problem that he is born with and impression, given pressured by his parents and the pre-school, of being weak and frail. In the third swimming sequence it is Anton, who is angry and puzzled. Again, Vincent beats Anton when they are adults. As Vincent rescues Anton from drowning, the subjective shot shots Vincent looks up to the dark sky and the stars, this is symbolic of his own struggle and of their struggle as brothers where DNA defines who you are and “valid or not” in this world.Vincent, meanwhile, through his determination and will of force is able to fulfill his dream of going to the stars and once again beats Anton in swimming. “Yo...
The Swimmer begins with a party at the Westerhazy’s house. All the guests there are of high social standing, judging by the fact that tennis courts, sail bags, and alcohol are mentioned repeatedly. The phrase, “I drank too much” comes up repeatedly and the guests mention this phrase repeatedly. One of these guest is Neddy Merrill. By the context of the story, the reader determines that Neddy is well off and enjoys being part of the culture that his status brings. This culture is one of drinking and one where time seems to stand still, regardless of where a person is, be it by the poolside or whilst traveling. Cheever’s The Swimmer is a deceptively easy read but has an overriding theme that can at first be missed if the reader only notices the weather and alcohol. What is the theme of the Swimmer?
The first, most noticeable theme, is alcohol. In “The Swimmer”, alcohol represents Neddy’s longing for a high-spirited life and an admirable social status. The drinking, serving, and craving for alcohol became a major influence for Neddy, as well as a way to maintain his social status. The story starts off talking about alcohol. They are all sitting around the Westerhazy’s pool complaining “I drank too much last night”, but as expected they are at the pool the next morning drinking again. Before Neddy decides to leave to swim from pool to pool, he drinks gin and continues to drink on his whole journey home. Almost every pool that Neddy stops at, he asks the pool owner for a drink. Neddy has already had plenty of drinks by the time he gets himself
Since Neddy decides that he is bored of his repetitive life, he decides to repetitively swim across all the way back to his home. Each pool represents a period of time, most likely a couple of months. Unfortunately, Neddy is trapped inside his routine and does not realize of the changes around him. For that everything he sees in his suburbs are the same, just middle class houses that all look alike. The story does an excellent job in showing how unaware Neddy is in his own decline. In John Cheever's "The Swimmer," Cheever uses diction and symbolism to express the theme of repetitive human life that decays daily.
The sport of rowing involves numerous combinations and classes of athletes. Boats can be rowed with or without coxswains (the non-rowing captain) and by 1, 2, 4, or 8 rowers. Each rower can handle one oar (sweeping) or two oars (sculling). Racing shells are currently being made with Carbon or Carbon/Kevlar combinations. The act of rowing involves the transfer of momentum by the rowers and their oars to the water. The momentum is transferred to the water by pulling on the oar and pushing with the legs (the feet are attached to the boat by restraints). This causes the seat to slide backwards and the oars to pivot on the riggers. Each stroke is made up of four basic parts: catch (blade vertical in the water, knees bent, arms forward), drive (legs straight, arms pulling toward the body), finish (oar out of water, blade vertical), recovery (body moves forward, blade turns from vertical to the horizontal). For some of the basic forces acting on a 4+ (coxed four) see Figure 1.
If you enjoy racing but not pressure, there are B meets which are just for fun but you still earn ribbons. More competitive swimmers can swim at A meets, which count for points towards your team’s end of the year total. At the end of the season, there are all-stars for those who are more competitive, where the fastest swimmers in the Northern Virginia Swimming League compete. For those who do not even want to compete, practices are still a fun way to participate in the sport of swimming. Also, practices are completely optional and being an astounding swimmer is not necessary to
My stomach feels like a rock trying to sink me down to the bottom of the pool. I hear the long whistle signaling me to step up onto the block.s. I step onto the creaky blocks and get ready. Adrenalin rushes through me ready to propel me into the water. The announcer tells us to take our marks. A few short moments after, I hear the long beep which signals me to dive into the water. I hit the water with a graceful splash. The bitter water shocks my system and then sends me into an all-out sprint. I race through the water trying hard not to look at my teammates next to me. As I get closer to the wall I see some of my teammates cheering me on. It feels as if their cheers are propelling me through the water. When I fling into a flip turn I glance at my competitors and I can see I am in front. I push a little bit harder and hit the wall with all my might. I look up at the scoreboard and see that I got first! My legs feel like jello as I get out of the water. Some of my teammates pat me on the back and say things like “Good race,” or “Nice job,” I mumble thank yous and continue on my way to talk to Coach. When I get to my coach she looks very surprised which startles me a bit. “Wow!” She exclaims “I'm really glad I got to see what you can do! Great Job Becca,” My coach says while patting me on the back. I head off to hang with some of my new friends. Even though I was so nervous in the beginning I know
One balmy summer morning my friends convinced me to come swim in Grapevine Lake, which would be very enticing if I was a strong swimmer or had any swimming experience whatsoever. However, I’m not going to ruin a good, scorching summer day staying home wasting my time playing video
Some of the events are named 4x4, 4x2, 4x1, and the 200-meter dash. For the faster runners, there is the 100-meter dash. A basic physical model describes sprinting. The model is utilized to anticipate the contrasts between the recorded times for races on a straight track and the curve. It is demonstrated that the decision of the running path has a non-negligible effect. Top sprinters use physics all through their whole race. Physics permits them to achieve a portion of the high speeds you may have found in Athens this past summer at the Olympic games. Top sprinters use physics all through their whole race. Physics permits them to achieve a portion of the high speeds you may have found in Athens this past summer at the Olympic games. The Physics is there throughout the race as well as included in the beginning. Propulsion, wind direction, air resistance and gravity are four forces that are activated when sprinting. For each applied force there is an equivalent and inverse power. At the point when the sprinter 's feet presses onto the track, the track applies an equivalent and inverse power on the leg of the sprinter, along these lines permitting the competitor to advance. The frictional force is a force that demonstrations the other way of the runner, along these lines restricting their movement. It happens when the track and sprinter 's feet connect and the ordinary power force between them. To do this, the sprinter inclines forward. This permits gravity to work with them as inclining causes gravity to pull the sprinter forward, and make movement of the legs less demanding as well. By inclining from the ankles and not the waist, sprinters have the capacity to run faster and all the more
A sport which gives great example of how biomechanical knowledge can be used to improve an athlete performance is competitive swimming, though the biomechanical analysis of competitive swimming can be challenging as the aquatic environment is not the natural human environment. In swimming kinematics variables such as stroke length, stroke frequency, speed fluctuation, and limbs’ kinematics and kinetics variables such as propulsive drag, lift force are drag force are analysed to improve athletes’ performance (Barbosa1, Marinho, Costa & Silva 2011. Athletes in swimming have to produce effective propulsive forces against the water, they are required to apply stroke techniques to generate enough force to accelerate through the water. For instance, a swimmers hand must move in a three dimensional curve if the hand moves in a straight line backwards, it cannot accelerate as much water to propel through it. Athletes also need to utilise effective kicking techniques to propel through the water (Barbosa1 et al,
I dip my toes in—feels cold. My nerves rise up and spread like fire throughout my body while I watch—while I wait. Stomach hurts. All those butterflies clash and crowd. They come every time that I race—it never fails. There is so much noise—the splash of water, talking, yelling, whistling, cheering.
Finish, Finish, Go, and Go you just set the new world record. Every four years lots of people gather around a pool cheering for Olympians. It is a very noisy place. A lot of Olympians that are part of the summer Olympics are very athletic, they swim all year around. The swimming Olympic history and background is very interesting. They have done so many new things over that past couple of years. They come out with new rules every year to make things more fair and challenging. There are a lot of events and tons of records that have been broke. A lot of Olympians have set future goals to stride for. I was swimming the 200 meter fly I was at a really good time when I had 50 meter sprint left at the end all I could think about was I’m going to set the new world record. Olympic swimming is a very fun sport it is very athletic. Every year in the summer time every one always sits around a TV watching this it is very famous in America. Swimmers from all around the world come and here and compete. There is a lot of competition there I have found out a lot about the history of swimming. There are a lot of events and tons of records that have been broke. A lot of Olympians have set future goals to stride for.
