If I Were a Man by Charlotte Perkins Gilman free essay sample
In Charlotte Perkins Gilman’s short story â€Å"If I Were a Man†she successfully shows the subconscious thinking of a young woman who wishes with her heart and soul she would become a man. The story is based on a young woman named Mollie Mathewson, who ends up becoming her husband due to her wishes to be a man. She then goes throughout the day as her husband, Gerald. â€Å"She was Gerald, walking down the path so erect and square-shouldered, in a hurry for his morning train, as usual, and, it must be confessed, in something of a temper†(Gilman 50). Gilman successfully brings this story to life by taking a third-person limited omniscient point of view, which allows us to see inside her innermost thoughts. Mollie Mathewson longs to be a man, because at this time men have all the power and pride women don’t. She is envious of all the things men can have. We will write a custom essay sample on If I Were a Man by Charlotte Perkins Gilman or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page â€Å"She felt what she had never felt before in all her life-the possession of money, of her own earned money-hers to give or to withhold, not to beg for, tease for, wheedle for-hers†(Gilman 51). For the first time in her life she gets to see what its like to have money that she does not have to share with anyone else. Men get to make the money while women stay home and take care of things around the house. Mollie now gets to experience life outside the house, and she also gets to feel what it’s like to not have to report to anyone. She is her own person now. During her day as Gerald she begins to take on his thoughts. She begins to think about women’s fashion and business sense. She particularly starts to dislike women’s hats. With the eyes of a man and the brain of a man; with the memory of a whole lifetime of free action wherein the hat, close-fitting on cropped hair, had been no handicap; now she perceived the hats of women†(Gilman 52). It’s interesting the way Mollie is taking on her husband’s thoughts. The reader would never think Mollie would think of women’s hats this way. The reader would think in spite of her being a man she would still think like a woman. On the train to work Mollie comes across a few men that Gerald rides the morning train with, and they begin having a biased discussion about women, that Mollie takes part in it. They talk about how women get whatever they want once they’ve got their mind made up and how men are smarter than women. Suddenly Mollie tells the men it’s time to wake up. She explains that women are pretty much the same as they are. Men and women are both people. Another thing Mollie said that is the most important quote of the story is, â€Å"As for Mother Eve-I wasn’t there and can’t deny the story, but I will say this. If she brought evil into the world, we men have had the lion’s share of keeping it going ever since-how about that? †(Gilman 55). Gilman shows men blame women for the way the world is, but it is both men and women who should equally be blamed for what goes on in the world. In the story the reader gets a feel for what Mollie is experiencing during her day as her husband Gerald. Charlotte Perkins Gilman does an amazing job getting her point across using the third-person limited omniscient point of view. At the end of the story Gerald is now conscious of new views and feelings about women that he never had before. Without Gilman’s use of the third-person limited omniscient point of view the reader wouldn’t have gotten that much out of the story.

Growing up, an analysis of isolation in winesburg, ohio.
Growing up, an analysis of isolation in winesburg, ohio. The back cover to the Viking Critical Library Edition of 'Winesburg, Ohio' by Sherwood Anderson reads: "'Winesburg, Ohio' is Sherwood Anderson's 1919 volume of interconnected stories about an ordinary small town whose citizens struggle with extraordinary dreams and grotesque disappointments" (Back cover; Viking Critical Library Edition of 'Winesburg, Ohio' by Sherwood Anderson, edited by John H. Ferres, Viking Press, 1996). The novel by the North-American writer is a collection of short stories, about the life, emotions and feelings of the townspeople of a fictional 1890s town. Emotions that sustain throughout the whole of 'Winesburg, Ohio' are isolation and loneliness, "particularly as these emotions take their source from failure of affection or of creative expression" (Edwin Fussell,'Winesburg, Ohio': Art and Isolation; The Achievement of Sherwood Anderson edited by Ray Lewis White, Chapel Hill Books, 1966). Furthermore an unknown author states that "The figures of 'Winesburg, Ohi o' usually personify a condition of psychic deformity which is the consequence of some crucial failure in their lives.[Grocery store, Mt. Orab, Ohio, Route 74] (LOC)Misogyny, inarticulateness, frigidity, God-infatuation, homosexuality, drunkenness - these are symptoms of their recoil from the regularities of human intercourse" (unknown author, studynet.com/novels/winesburg/isolation/).Failure of communication, the incompetence of self-expression and the universal condition of loneliness and isolation are emotions that tie together Sherwood Anderson's compilation of short stories, as well as the tale of the book's main character George Willard, who in the end will learn to accept these emotions and thus achieves maturity. Being the town's newspaper reporter, George becomes the person of contact for most of the town's citizens who suffer from isolation and loneliness. Therefore I am going to analyse how isolation manifests itself within Sherwood Anderson's novel 'Winesburg, Ohio'. I will do so by showing how the...

Mattel Toy Company Essay Example | Topics and Well Written Essays - 500 words
Mattel Toy Company - Essay Example In August 2007, the U.S. Consumer Product Safety Commission asked the consumers to stop buying 967,000 pieces of a certain toy manufactured by Fisher Price which is a subsidiary of Mattel Company (U.S. Consumer Product Safety Commission, 2008). These toys were recalled because the lead in paints used in toys was180 times more than the quantity allowed by law (ODonnell, 2007). This quantity of this toxic was clearly excessive and could cause a great deal of harm to the children who used it (U.S. Consumer Product Safety Commission, 2008). Besides this, a few of Products produced by Mattel Company were also said to contain small magnets which were very dangerous for the young children who played with those toys because of the harm to swallowing them. How did Mattel Toy Company respond to this situation? Any company that wants to stay in the market, be it a giant and a leading company like Mattel Toy Company would assure the society that the company is concerned about them. The first step that it took was to check their products immediately and consider itself accountable. It acknowledged that the lead in their paints was 0.11 percent while only 0.06 percent was allowed (ODonnell, 2007). Mattel Toy Company also recognized its responsibility and immediately identified and recalled about 1.5 Million products that were dangerous. According to one source, the company gave the consumers the benefit to return the products that were announced to contain excessive amount of lead in the paint (U.S. Consumer Product Safety Commission, 2008). Besides this, it also recalled all its toys that were said to contain small magnets. This was the result of deaths and surgeries of young children because of ingesting these small parts. The toys that were recalled because of magnets amounted to 18 Million (Mattel, 2007). All the recall information was posted on the internet and all the consumers were made aware

MPH599 - Culminating Project Mod 2 Case Assignment - Essay Example Theyre also number one on the list for children who have obesity. Risk factors for children to become type II diabetics, include, overweight and obesity, as well as distribution of body fat, high or low birth weight and rapid weight gain in children, physical inactivity and sedentary pastimes, fetal exposure to maternal gestational diabetes, failure to recover from the dynamic metabolic system changes of puberty when overweight or obese, and signs of insulin resistance untreated. Being a member of ethnic populations such as the American black, Mexican American, and Native American increases risk this disease. Essentially every civilized country in the world has had a sudden increase in children who are obese and therefore, children who have type II diabetes. Spain and the UK are second and third in numbers of children who have obesity as well as type II diabetes. Unfortunately type II diabetes in children leads to early hypertension and cardiovascular disease and peripheral vascular disease. The fact that these children are so overweight causes a great deal of difficulty maintaining joints and these children as they hit early adulthood often havening degenerative joint disease. Appropriate screening and follow-up education on such issues as nutrition, number of hours in front of the television set, or number of hours playing video games is important in the school systems today. The average child who develops early-onset diabetes is usually in the age range of 5 to 15.(Healthy people 2020). Type II diabetes in children is one of the most serious public health challenges of the 21st century. Thereve been more than $2 trillion spent nationally on health care issues related to child type II diabetes. This actually only amounts to 3% of all public health activity. Its already estimated 250,000 more public health workers will be needed by 2020 to handle the number of issues that are growing, with childhood as well as adult diabetes as

Information System Essay Example for Free
Information System Essay The introduction of information system has heave effect on arising of ethical, social and political issues. These issues should be dealt with at individual, social and political levels. The computer professional and users have the responsibility of maintaining relationship with each other given that critical decision made poses significant consequences to the involved parties. Ethical issues are those principles of what is right and wrong that can be used by individuals acting morally as they make choices that guide their view towards new information technology. They have to behave ethically by not stealing, being honest, keeping promises and doing ones job right for computer users. Consequently, computer professionals are to follow good professional standards and practices, educate non computer professionals on how the systems affect people (Alter, 1999). They are also to ensure the latest knowledge and technology is attained through high level of professional competence. Thus the five ethical, social and political issues in information system that call for moral steps to be taken in making decisions are; The information rights and obligations Individuals and organizations should have rights and obligation on information so that they are able to protect their information in the system. The ethical issue here are on what condition should privacy be raided or what justifiable self-effacing inspection. Socially, people have to be ascertained privacy when using the information system. But will the expectation of the society be extended to criminal conspirators. Politically, are securities teams monitor or maintain individuals’ data from sites? Property rights and obligations There should be a way of protecting the traditional intellectual property rights in a digital society. This will facilitate tracing and accounting for information ownership by eliminating difficulties associated with property rights. In respect to social issues, the society should be in a position of sharing information so as to eliminate law breakers and politically, the government should protect investment of creators by setting new protection measures needed. Accountability and control The issue of who is to be held accountable or liable for the harm done to individuals or for the collective information and property rights. The ethical issue is on who is responsible morally for the consequences of the use of hardware or software. Socially, the issue brought out is on what the expectation of the society should be in allowing service provision from information system or can people be in a position of trusting the quality of the software, data (Gupta, 2000). In addition, the political issues of on what extent should the government intervene so that it may protect service providers and users. System quality The standards of data and quality of system should be defined that society should demand in order to protect individuals’ rights and the safety in the society. Ethically, the point at which services are to be released for consumption has to be defined. On social issues, whether people are to be convinced that the information systems are infallible and politically whether laws of accountability and responsibility should be set (Alter, 2006). The government has to step in and develop standards on the quality of data, software and hardware. Quality of life Certain values have to be preserved in an information and knowledge-based society against violation. The information should be in a position of supporting the cultural values and practices. Information system has led to reengineering of work, health risks like computer vision syndrome and radiation from display screens. In addition, it weakens traditional boundaries; it is vulnerable to system failures, slow responses to change due to efficient market place and problems associated with centralized policy decisions (Curtis Cobham, 2008). Even though information system poses several issues to business, it must be incorporated in business operations for it is vital in coordination and communication within the business. Additionally, the benefits of information system are much more than the few shortcomings it carries. 2. An information system refers to the combination of information technology and people’s activities while using the technology in order to support operations, management and ease decision making. In essence, it’s the interaction between people, processes, data and technology (Beynon-Davies, 2009). It helps in controlling the performance of business processes. An information system works in a way that human and machines perform tasks to produce products and services for customers. Information system is made up of several components of management, organization and technology. These are; the people, hardware, software, data, network resources, types of information products and the way the components perform i.e. input, processing, output and storage through controlled activities. People resources are made up of end users and information system specialists while hardware consists of machines and media. The soft ware resources comprises of programs and procedures in storage of information and processing while data consists of data and knowledge sources (Mader, 1979). Network resources are made up of communications media and network which facilitate technology in innovation and communication. 3. In an organization, information system is vital given that it helps in decision making by employees and managers. Additionally, it wires an organization strategy for competitive advantage through innovation using information system and facilitating business processes and operations. In a business, information system provides managers with important information about sales, inventories and all other vital data that will help in managing an organization (Edwards, 2001). It facilitates effective communication between the different levels of management through collection, processing, storing and dissemination of data in the organization. I believe that information system is very important in the organization for it enhances communication within the organization. By incorporating modern information technology in management of the business, managers will be able to come up with decision with much ease. Furthermore, it provides essential data for analysis of performance of various levels in the business thus enabling motivation, training, recruitment and promotion. Lastly, it provides data and analysis which are useful in making good decision of how, when and where to employ human resources in order to achieve the goal of the organization. 4.  I agree that there is a sustainable competitive advantage in business. Sustainable competitive advantage can only be attained through the use of information system where it facilitates innovation and decision making that will enable a business to remain competitive in the market (O’Brien, 2008). The organization will therefore make use of information technology to reengineer internal processes of the business thus cutting on cost and ensuring quality products making them to remain competitive in the market. In short, a sustainable competitive advantage is possible with implementation of effective information system with proper and focused management.

Ways in which this could potentially happen is by offering basic beyond-the-box products with the purchase of a PC and aggressively encourage upgrades and additional features customers can’t refuse. Another way to counter other PC manufactures is through differentiation. By Gateway focusing on operating its build-to-order method as efficiently as possible, exploiting its distinct third channel of stores and staying technologically as innovative as possible, it is able to differentiate itself apart from its competitors.      Lastly, in addition to its pursuit of the consumer market, I think Gateway could benefit from more assertively targeting the business segment that has been ruled by Dell. It’s a fact, that PC’s sold for business-use tend to be of a higher quality and therefore, more expensive with higher margins. In 2000, 65% of Dell’s PC sales went towards the business sector whereas Gateway’s main market was from consumer sales, which is often less profitable. If Gateway could go after the business market, without completely losing its consumer sales base, it would be able to better compete, especially with Dell.

In the Light of the Energy Systems Used During Prolonged
Coursework 2 Name: Mohamed Abdulwahab Exercise metabolism Title: In the light of the energy systems used during prolonged endurance events, critically analyse the nutritional strategies that a marathon runner should adopt before and whilst running a marathon in temperate environmental conditions (16-18oC). 1. Introduction: 1. 1 Energy intake: 1. 2 Fluid intake: 1. 3 Carbohydrate intake: 2. Building energy and fluid: 1. Before competition: 2. During competition: 3. Nutritional recommendation: 3. 0 Summary: 4. 0 Reference: 1. 0 Introduction:The term energy system refers to the body’s ability, or power, to do physical work. The energy system requires to do body work that takes several different forms: mechanical, electrical, light, radiant, and heat (Economos, 1993). Energy system is like matter, which can neither be created nor destroyed (Bortz, 1993). It can only be changed into another form; therefore energy is constant cycle in the body and environment (Nelson, 1993). Potenti al energy is stored energy which is ready to be used. Kinetics energy is active energy which can be used to do work (Burke, 1991). Energy balance n a physical activity requires a base of sound nutrition to supply the substrate fuels, which along with oxygen (O2) and water (H2O) meet widely varying levels of energy demand for body action (Gollan, 1991). Fuel sources are the basic energy nutrition in the diet, primarily carbohydrate and some fat (Read, 1991). Their metabolic products-glucose, glycogen, and fatty acids-provide ready fuel sourced for the chemical energy reactions within cells (Murray, 1998). The main energy compound of the body cells is needed during a marathon run is aerobic system (Horswill, 1998).It has rightly a form of energy currency of the cell. A long-term energy system, when exercising more than 2 minutes is required O2 dependant, or aerobic energy system (Pate, 1992). A constant supply of O2 in the blood is necessary for continued exercise (Branch, 1992). Espe cially cells organelles, the mitochondria are located within each cell, produce large amounts of adenosine triphosphate (ATP) (Hargreaves, 1996). The ATP is produced mainly from glucose and fatty acids and supplies the continued energy needs of the body (Dillo, 1996).When the fuel nutrition becomes depleted during exercise, as an energy demands increase the body burns blood glucose and muscle glycogen as well as reserves from fatty acids to provide energy (Angus, 1996). With prolonged exercise levels of these nutrition fail too low to sustain the body continued demands, fatigue followed and exhaustion threatens (Fabbriao, 1996). A marathon runner, energy system is defined as aerobic capacity, which depends on the body’s ability to deliver and the use of O2 in sufficient quantities to meet the demands of increased level of exercise (Coyle, 1986).O2 uptake increases with exercise intensity until either the demand is net or the ability to supply it is exceeded (Hammert, 1986). T he maximum rate that the body can take in O2, or aerobic capacity is called the Vo2max the maximum uptake volume of O2 (Ivy, 1986). This capacity determines the intensity and duration of exercise that an athlete can perform (Coyle, 1986). A long-distance race requires the sustained production of high rates of energy production, with the typical contribution of aerobic energy system varying according to the duration of the race (Costill, 1985).Aerobic metabolism accounts for the greater majority of the energy cost of long-distance events, especially half-marathon and marathon races (William, 1996). The elite level of long-distance running, particularly in males, is dominated by African runners, are outstanding competitor in half-marathon and marathon events (Wilson, 1996). 1. 1 Energy intake: Endurance athletes are involved in events where there is continuous movement for longer than 30 minutes (Burrin, 1996).Some endurance sports combine periods of slow, continuous movement with per iods of fast, quick burst of movement, and other endurance sports require continuous movement overlong-distances or time periods (Tsintzas, 1995). In the types of activity there is a premium on supplying sufficient energy and fluid to assure that the athlete does not become exhausted or over-heated from the continuous energy burn (Williams, 1995). A failure to supply sufficient energy of the right type will lead to early fatigue and poor athletic performance (Williams, 1995).The goal for the endurance athlete is therefore to establish a workable strategy for supplying sufficient energy and fluids (Williams, 1995). Before and during practice and competition to sustain muscular work for a long-duration and at the highest possible intensity (Wilson, 1995). Aerobic metabolism is the energy system of greatest importance for endurance athletes. In this energy pathway oxygen is used to help transfer phosphorus into new ATP molecules (Burrin, 1995). Aerobic metabolism occurs in the mitochon dria of the cells, where the vast majority of all ATP is produced from the entering acetyl-CoA, (Burrin, 1995).Fast can be converted to acetyl-CoA through a process called beta-oxidative metabolism pathway (Burrin, 1995). This pathway is very oxygen dependant which means that fast can only be burned aerobically (Wilson, 1995). The ability of an athlete to achieve a steady state of oxygen uptake into the cells is a function of how well an athlete is aerobically conditioned (Coggan, 1992). An athlete that frequently trains aerobically is likely to reach a steady state faster than one does not train aerobically (Coggan, 1992).In theory once an athlete reaches a level of oxygen uptake that matches oxygen requirement for the given level of exertion (Coggan, 1992). The exercise could go on for as long as the body’s carbohydrate level and fluid did not reach a critical state (Sherman, 1996). For instance a long-distance runner is in a steady state could continue running provided the runner replaced the carbohydrate and fluid that are used in the activity (Sherman, 1995). Therefore, endurance is enhanced with a periodic intake of carbohydrates and fluid during the activity (Swanson, 1992).Athletes with different levels of conditioning are likely to achieve steady state at different levels of exercise intensity (Sherman, 1995). When athletes are being well-conditioned they might be able to maintain a steady state at a high enough level of exercise intensity to easily win a race (Williams, 1995. In other words, they can go really at a fast paced but still provide enough oxygen to your cell to satisfy your aerobic needs (Swanson, 1992). 1. 2 Fluid: As athletes exercise there is an inevitable loss of body water through sweat (Economos, 1993).The cooling system plus the normal urinary water loss may amount cover 10 litres of daily water loss when exercising in a warm environment (Borts, 1993). In a hot or humid environment water losses may exceed three litres per ho ur, but may be less than 0. 5 litres per hour cool dry environment (Nelson, 1993). Despite the high rates of sweat losses experienced by athletes, most athletes replace on fifty percent of the water that is lost, a behaviour that inevitably leads to progressive dehydration and a decline in performance (Nelson, 1993).Researches have clearly demonstrated that even a slight dehydration of two percent of body weight causes a measureable decrease in athletic performance (Borts, 1993). Therefore, when athletes take steps to satisfy fluid requirements, they are helping to guarantee optimal athletic performance (Economos, 1993). 1. 3 Carbohydrate: Athletes require carbohydrate during both low and high intensity activities (Burke, 1991). When carbohydrate stores are depleted the athlete quickly becomes fatigued and performance drops dramatically (Gollan, 1991).However, since the storage level of carbohydrate is relatively low gen compared fat stores; athletes must make a conscious effort to replace carbohydrate at every opportunity (Read, 1991). When having high levels of stored carbohydrate (glycogen) and consuming carbohydrates during exercise that last up to an hour or more are well-established techniques for optimizing athletic endurance (Murray, 1998). Consuming carbohydrate during exercise helps to maintain blood sugar (glucose) and insulin, which encourages sugar uptake by working muscles (Horswill, 1998).This helps to increase the muscular metabolism of carbohydrates and also helps to assure that carbohydrates are not depleted during exercise (Horswill, 1998). The concentration of carbohydrate consumed early during endurance running may influence the degree to which the athlete gets gastrointestinal (GI), discomfort (Murray, 1998). It was found that a 5. 5 percent (13 gram of carbohydrate per 8 ounces of fluid), carbohydrate solution produced the same level (relative low) of GI distress as plain water (Pate, 1992). A 6. percent (18 gram of carbohydrate per 8 ou nces of fluid), solution, on the other hand, doubled the incident of distress when athletes were asked to perform the same exercise (Branch, 1992). In addition, only the 5. 5 percent carbohydrate solution imparted a significant improvement in performance (Branch, 1992). In a study of marathon running performance, that are running over 26 miles, were asked to consume either water, a 5. 5 percent carbohydrate solution or a 6. 9 percent carbohydrate solution on three occasions (Pate, 1992).The fastest times were recorded when they consumed the 5. 5percent carbohydrate solution, while consuming the 6. 9 percent solution resulted in times that were similar to consuming plain water (Hargreaves, 1996). Although, athletes have a tremendous need for carbohydrate, trying to provide too much too fast causes difficulties and may detract from performance (Dillo, 1996). Therefore, it appears clear that having a carbohydrate containing beverages during exercise is a very good thing to do (Angus, 1 996).Resynthesis of glycogen following activity is also important, since glycogen reserves are severely depleted following activity lasting an hour or longer (Fabbrioa, 1996). The efficiency of glycogen resynthesis is dependent on several factors, including: (1) the timing of carbohydrate intake, (2) the amount of carbohydrate consumed, (3) the type of carbohydrate consumed, and (4), the degree to which muscles has been damaged during the exercise (Fabbrioa, 1996). 2. 0 Building energy and fluid: The importance of building and maintaining energy reserves to support endurance exercise is well-established (Angus, 1996).It is very clear that endurance athlete who begins competing with more stored carbohydrates have more available at the end of the competition (Coyle, 1996). This difference alone may be enough to determine the winner. In addition, athletes who are better hydrates during competition perform better than those who are less well-hydrated (Coyle, 1996). Having optimal carboh ydrates and fluid intake does not happen automatically. It is something that must occur with foresight and planning (Angus, 1996). 2. 1 Before competition: When consuming carbohydrates prior to exercise, there is improved performance.The general recommendation is for athletes to consume between 800 to 1200 calories during the hours that precede competition (Costill, 1985). Foods consumed prior to competition should be foods that have been consumed without difficult prior to training (Costill, 1985). Trying to improve carbohydrate status before a competition by trying out new foods, like gels or sports drinks is an almost guaranteed formula for competitive disaster (Costill, 1985). Consumption of fluids prior to competition is also important and since glycogen storage requires additional fluids carbohydrate consumption should lways take place with substantial fluid intake (William, 1996). Since it is common for athletes to drink only when thirsty a conscious effort should be make to consume fluids even when not thirsty (William, 1996). Getting and staying well-hydrated may be the single most important thing athlete can do to assure good athletic performance (Wilson, 1996). Since it is almost impossible to adequately replace all fluids lost during training or competition it is useful for athletes to enter the exercise in a well-hydrated state (Burrin, 1996).It is impossible to become well-hydrated during exercise if athlete enters the exercise poorly hydrated to begin with (Burrin, 1996). Assuming that ample fluids have been consumed during the day leading up to the re-competition or practice athletes should consume an additional 10 to 13 gram of fluid approximately two hours before the exercise begins (Wilson, 1996). After this fluids should be consumed every 15 to 30 minutes to maintain prior to exercise (William, 1996). The athlete will know if you’ve adequately hydrated yourself by checking on the colour of the athlete urine (Tsintzas, 1995).Dark urin e suggests that athlete is not well-hydrated, while clear urine suggests that athlete is well-hydrated (Stanzas, 1995). Using sports beverages (lucazad) prior to exercise is useful because they provide the two things athletes need the most: carbohydrates and fluids (William, 1995). Since carbohydrate is typically the limiting energy substance (that will run out before fat or protein runs out) in exercise (William, 1995). When starting exercise with more of it is in the tissues should aid exercise endurance (William, 1995).In low-intensity but long-duration exercise, fat may be the primarily fuel, but fat requires carbohydrates to burn completely (Singh, 1995). In either case, when carbohydrates (glycogen stores and blood glucose) are depleted, exercise performance is dramatically reduced (Wilson, 1995). This basis behind carbohydrate loading is to put as much carbohydrate in the tissue as they can hold (Wilson, 1995). 2. During competition: A marathon race where fluid are available at regular intervals, the athlete should take full advantage of each fluid station and consume fluid (Burrin, 1995).Since water is constantly being lost, frequent and regular consumption of fluid helps to maintain the body water level (Burrin, 1995). To understand how much fluid an athlete needs to consume during practice or competition, a log should be maintained with the amount of fluid consumed and the beginning and ending weight of the athletes (Sherman, 1995). If an athlete consumes 26 gram during practice and weighs 26 gram less at the end of practice than at the beginning this athletes should learn to consume an additional 26 gram of fluid during practice or competition (Sherman, 1995).Consumption of fluids that contain carbohydrates is important during exercise or competition and properly designed sport beverages can benefit in providing both fluid and carbohydrates quickly (Coggan, 1992). Carbohydrate solution of between 5 and 6 percent delivers both the carbohydrate and th e fluid quickly (Swanson, 1992). A higher carbohydrate concentration slows delivery to the muscles by delaying gastric emptying and may increase the risk of gut upset (Swanson, 1992). A small amount of sodium helps drive the desire to drink and in so doing helps to assure that the athlete stays better hydrated (Coggan, 1992).Sodium may also benefit in getting the water and carbohydrate absorbed more quickly as well as helps to maintain blood volume (Economos, 1993). Maintaining of blood volume is an important predictor of athletic performance (Economos, 1993). There is some evidence that hyponatremia (low level of blood sodium), which results from large losses of sodium in sweat that goes unreplaced, occurs endurance and ultra-endurance events (Borts, 1993). This is a rare but a serious condition that may result in comas, or death (Nelson, 1993). The beverage should be taste good to the athlete.The taste sensation may be altered during exercise so there is no guarantee that a fluid, athlete enjoys drinking while exercising. Make sure that an athlete tries different flavours during exercise to determine what is best liked. The carbohydrate should be from a combination of glucose and sucrose. Beverages containing predominantly fructose increase the risk of creating gut upset. 2. 3 Nutritional recommendation: There are several rules of nutrition that apply here. Among them is the idea of the need to consume a wide range of variety of foods to assure that the body is exposed to all of the essential nutrients (Burke, 1991).On the backside of this rule, there is another benefit. By consuming a wide range of variety of foods, athletes can avoid being exposed to any potentially toxic substances that are more prevalent in some foods (Gollan, 1991). Therefore, eating a wide range of variety of foods is a good nutritional rule to live by (Read, 1991). Another rule is the idea that it is possible to eat too much of something, even if athletes think it’s good for th em (Read, 1991). Learning to balance the diet through variety will help ensure the body of both proper maintenance and adequate nutrient intake (Gollan, 1991). 3. Summary: In general, athletes with long training schedules should focus on the consumption of diets that are high in carbohydrate and should develop a drinking habit that frequently delivers fluids to the body. While fats, constitute a major proportion of burned energy for endurance (aerobic) activities the storage capacity for fat is relatively high for even the leanest athletes. The storage capacity for carbohydrate, however, is limited. Since fats require some carbohydrate to be completely burned, the limited storage capacity for carbohydrate cam limit the body ability to burn fat during exercise.To overcome this limitation athlete should be constantly vigilant to keep body stored of carbohydrate at maximal levels before activity begins and should replace carbohydrate during activity throughout whatever means are availa ble. A failure to supply suffienct carbohydrate before and during endurance activity will significantly reduce athletic performance. 4. 0 Reference: †¢ Economos, D. , Borts, Z. , and Nelson, R. 1993.
