Analysis Of The Free-throw Shot :: essays research papers

Analysis of the Free-Throw Shot When deciding about a movement to study, I thought about many, and very few interested me. Then I decided to choose something that was very important to me. Shooting the basketball, and more specifically the technique in performing a free throw. I thought by looking more closely at the details of a movement I have been doing since a small child. I thought possibly I could learn something that would give me an advantage in my shot. The application of this particular movement is for shooting a free-throw, which is a stand still uncontested shot. There are a few rules that go with shooting a free-throw, such as you have to be behind the fifteen foot line, called the free-throw line, and you can't cross that until after the ball makes contact with the rim. When performing this skill you should also be aware of the other factors that could influence your accuracy in performing the free-throw. The rim is fifteen feet from the free-throw line on center. Also you should be aware of the fact you can fit three basketballs through the rim at the same time if placed together. Also the rim is ten feet high from the floor, meaning you have to make sure win shooting the ball, that the angle is higher than ten feet at its peak so then on its decent to the basket it will have a chance to go in. If you don't get it higher than ten feet it has no chance to go in. When you start talking all these angle's and trajectories, you can begin to understand why some people are accurate and some are not. Shooting free-throws is not a thing of chance or luck. It is something that takes repetition. To be a good free-throw shooter you need to have a repetitive action, not something that changes every time. Since the conditions are predictable it is very easy to become a good repetitive free-throw shooter. If you would be unsure about the correct movements, it would be beneficial to study the movements of someone who is one of the best at what you were studying. The best of our time would be Mark Price of the NBA. He has a career free-throw average over ninety percent, which by free-throw standards is very good. To give you an idea of how well that is, you need to examine the averages. If a person was to shoot over seventy percent for the year, they would be considered a decent free-throw shooter. Someone over eighty percent is

The Ball and Chain: Why The NCAA

Be The term, â€Å"student athlete† is a polarizing one. In todays America, college sports particularly football and basketball, are as much a part of the sports enthusiast's landscape as is any professional sport. In any case, with enthusiasm comes money. In this case, billions of dollars are generated by television viewership, merchandise sales and university boosters. College athletes are the driving force behind an industry where television executives, university presidents, athletic directors and coaches are compensated in a manner which makes them among the most wealthy eople in the world.The athletes receive in return an education from a well respected university, along with name and sometimes facial recognition in their fields of interest. However, the student on a physics scholarship receives the same opportunity for education and name recognition in his field that the athlete does. The difference is, the physics student isn't selling millions of dollars worth of Jers eys. The physics student is also allowed to pursue compensation for applying his craft as he sees fit while enrolled at the university while the athlete is not allowed to work or ven accept perks brought about by his celebrity.The National Collegiate Athletic Association (NCAA) serves as the oppressive monopoly which seeks to capitalize on the dreams of young athletes by requiring their servitude, likeness and name in exchange for the slimmest of opportunities to attract employment in their field of interest. Like any other oppressor or monopoly that came before it, the NCAA should be abolished and replaced with a model that is mindful of equality, as well as human and civil rights.The NCAA has blocked every road that an athlete may have to apitalize on his hard work during his time at his respective university. Only recently has the legality of such roadblocks been challenged. Due to its litany of regulations designed to stifle player movement or compensation, many, such as Pulitze r prize winning author and historian Taylor Branch, have argued that the current structure of the NCAA rivals that of a slave plantation or drug cartel.Branch scoffs at the correlation between the terms â€Å"student athlete† and â€Å"amateur,† stating in an article in The Atlantic, â€Å"No legal definition of amateur exists, and any attempt to create one in nforceable law would expose its repulsive and unconstitutional nature a bill of attainder, stripping from college athletes the rights of American citizenship. † (Branch 2). At the heart of that argument is the question, what constitutes an employee? Blacks Law dictionary defines â€Å"employee† as â€Å"a person in the service of another under any contract of hire, expressed or implied, oral or written, where the employer has the power or right to control or direct the employee in the material details of how the work is to be performed† (Muhl 2). An athletic scholarship is clear example of a ritten contract which both overtly and implicitly stipulates that the school is willing to exchange an education for the athlete's services on the school's sports team.

The Heart Of Blood Cells - 1424 Words

It should be common knowledge that red blood cells are one of the most important details of the body, but unfortunately, that is not the case. Most people believe that the heart makes blood because it is common knowledge the heart is known as the main component of the body. However, the bone marrow in the body is what produces the red blood cells, platelets, and white blood cells. The general population may also believe that having more than the normal count of white blood cells could be beneficial to the immune system. Nonetheless, having more than the normal count could be diagnosed as a cancer. On the other hand, there is a bone marrow disease that leads to a rise in the number of blood cells called Polycythemia Vera (PV) which is usually found in adults over age forty. Polycythemia Vera (PV) is not an uncommon disease. Even though it is regularly found in older adults from age 40 to 60, it can also be found in people even younger. â€Å"Statistical data indicate an incidence of 1 to 2 per 100,000 per year, which increases with age† (Najean and Rain Par.2). The biggest effect of this disease is on the cardiovascular system and because of that, it has a direct impact on the quality of life for the patient and is quite expensive to treat. The Polycythemia Vera Study Group, the France division, was proposed an experiment to try different treatments on individuals who had the disease with ages sixty-five and older.

Throughout the 19th century, many kids in England were being overworked and put in dangerous situations that could have potentially cost them their lives. Kids were not being right and were having to sacrifice their education so companies could earn a better profit. Child Labour is a well-known term for kids who are worked too hard for their age without much, or no, pay. Broadly speaking, the term child labour is defined as the employment of children in any work that deprives them of their childhood and dignity, and that is harmful to their physical and mental development(Ortin-Ospina). During the 19th century, the new factories and mines were eager to find workers and had simple task that they believed were easy enough to be done by children. This gave companies an idea, they could hire children to do the work by paying them less than an adult. Companies could easily discipline children and would be much cheaper to hire (Child Labour). Kids would start to work some at the age of five or six in agriculture gangs or places far away from their homes. Some children would have to work in the worst forms of child labour for less than minimum wage (Ortin-Ospina). Sometimes you may even find more children working in an area than adults. Because of thei r size and youthful energy there were jobs that children performed as good or even better than adults (Victorian Child Labour). Don’t waste time! Our writers will create an original "Victorian Child Labour" essay for you Create order A majority of kids were hired to work for these low prices. About 120 million children between the ages of 5 and 14 work full-time and another 130 million work park time (The Paradox). The National Archives states that around 49% of the workforce was under 20 in the year 1821(Child Labour). The working conditions that these kids had to work through were horrible. The conditions were so bad that kids were in constant fear of being injured or having their life taken; cave-ins, explosions. The children had to perform multiple different jobs such as coal mining, textile mills, and even prostitution. They would work around fourteen hour days starting and 6 am and working until around 8 pm. They also only made a fraction of what adults made, even though they were worked hareder. Being forced long hours with health risking conditions should have never been allowed. During most of these jobs, health violations made it extremely dangerous. Emma Griffin states in her Article, Child Labour, that, All children laboured under the same disadvantages, though, working for very low pay, performing work that was dirty and dangerous, and usually working long hours as well.(Griffin). Airways in mines were thick due to the or ventilation, lose eyesight from the strain of eyes of trying to s ee because the mines were so dark, and some even formed spine deformation from having to walk being stooped over constantly (Victorian Child Labour). Kids were not protected from their employers and older co-workers (Griffin). There was a chance of kids being beaten up if they had made a mistake, were late, or fell asleep (Victorian Child Labour). The risk of having an accident while working was very high and in Europe in 1825 28.25% of kids ten to thirteen had an incident (Ortin-Ospina). One of the biggest cases that shows of the dangerous of the factories was the case of Martha Appelton in 1859. Martha was thirteen and hired to pick up loose cotten from under the machine. One day, Martha had fainted while doing her work and her hand got caught in an unguarded machine. From this accidnet, all her fingers were sliced off and she ended up being fired for no longer able to work well (Child Labout). Although most parents knew what was going on in the factories there was nothing they could do about it because they needed the money. Roger Langon is an example of this; after his parents found out that he was nearly killed by his drunk coworker, they realized there was nothing they could do because all the other parishs were full and they needed the money (Griffin). While all these kids were working full time jobs, they were not able to recieve an education. Kids were working fourteen hour days, then having to come home to help their parents out at home, then sleep, and do it all again. There was not a few minutes left in the day for them to learn a quick thing. During this century work was valued over education immensly. Although, during the end of the 19th century people started to realize that they wer not little adults and needed to get an education as well (Child Labour). In countries where children tend to work longer hours, it is more common that working children remain out of school (Ortin-Ospina). Laws started to be made to ensure that children would still be recieving and education while working. After 1867 a law was made that determined that no factory could hire a kid under the age of eight and any kid from the age of eight to thirteen were required to recieve ten hours of education a week (Child Labour).
