Home Economics - Why is nutrition important to sports people?

Extracts from this document...

Introduction

In order to obtain an idea for a task I could research, I decided to do an initial brainstorm of all the areas that would be possible to complete the project on (see fig1, next page). The factors that would affect my decision of what area to choose, were how easy it would be for me to research the topic, whether I knew people I could speak to about it and whether it was something that interested me. Because of these, I decided to research into nutrition for rowing. This was because I am a rower myself which meant that it would interest me, I would already know about the topic and I knew a variety of people who would be able to provide information and help on the subject. For research: To start the project I needed to carry out some preliminary, general research into the sport and its demands. The following are some things I needed to research: o Sports nutrition o Nutritional requirements of a normal person o Nutritional requirements of a rower o What a rower should eat on the day of, and during the week before, a race. Preliminary research Sources To ensure that I could gat a balanced set of information I decided to use data from several media types. These could include magazines, people, websites, books and companies. The following are some sources I thought would be useful: o ARA (amateur rowing association) o Internet - including rowing websites, BBC website, nutrition websites etc. o Sports magazines o Books form library o Olympic foundation o IOC consensus statement on sports nutrition 2003. The majority of the following initial research was obtained from the Australian International Rowing website, published ARA information and Amanda McCulloch (a sports nutritionist who often specialises in rowing, who gave a talk to my rowing team and allowed me to interview her). Why is nutrition important to sports people? The nutrition of an athlete is very important to their success at the sport. ...read more.

It is especially important for athletes in other special needs groups such as teenagers, or vegetarians. The following table lists and explains the uses of the important nutrients and where they can be found. Vitamin Main functions Sources Deficiency Excess A Essential for vision in dim light; necessary for maintenance of mucous membranes, skin and growth. As retinol in milk, fortified margarine, butter, cheese, egg yolk, liver and fatty fish. As carotenes in milk, carrots, tomatoes, dark green vegetables. Reduced night vision; loss of sight through gradual damage to the cornea. Lowered resistance to infection. Vitamin A is stored in the liver and toxicity can occur. D Promotes calcium and phosphate absorption from food and is thus essential for bones and teeth. Sunshine, fortified margarine, oily fish, egg yolk, fortified breakfast cereals. Failure of bones to grow and calcify leading to rickets in children and osteomalacia in adults. Vitamin D can be toxic. E Protects cell membranes from damage by oxidation. Vegetable oils, nuts, vegetables and cereals. Deficiency may occur in premature infants or due to malabsorption. Not known. K Essential in the formation of blood clotting proteins. Synthesis by bacteria in the gut. Dark green leafy vegetables, e.g. cabbage, brussel sprouts and spinach. Deficiency leads to an increased clotting time. Not known. Water soluble: Ascorbic acid Involved in the production of collagen - used in the structure of connective tissue and bone. Also aids wound healing and iron absorption. Fresh fruits especially citrus fruits and green vegetables. Also found in potatoes. Scurvy results from prolonged deficiency. Poor wound healing and bleeding gums. May lead to kidney stones. Thiamin Involved in the release of energy from carbohydrate. It is important for the brain and nerves which use glucose for their energy needs. Cereals, nuts and pulses are rich sources. Green vegetables, pork and fruits and fortified cereals contain thiamin. Deficiency leads to beriberi. Alcoholics sometimes develop deficiency. ...read more.

Conclusion

207 kJ Protein 3.3 g Carbohydrate: 4.63g * This values for this meal show that it is very high in protein, which is useful, because at the time it would be eaten protein would be needed the most to aid recovery overnight. Also, the pasta provides a rich and readily digestible source of carbohydrates to replace lost energy. This makes the meal useful as a dinner at the end of a race day or intense training day. Evaluation This was a very successful practical. The time plan was adhered to well without any problems, and the outcome was effective, both in satisfying the task title and in taste and appearance. In future, should this meal be made again, I would vary the use of cheese so as not to be restricted just to parmesan and cheddar, but to include others. It would be possible to conduct a taste testing survey, varying the different cheeses used. This would probably be more useful in obtaining research towards different ways of answering the task title. 5) SNACK - FLAPJACK Oats: Water 8.8 g Energy 383kcal, 1607 kJ Protein 16g Carbohydrate 67g Honey: Water: 17.1g Energy: 304 kcal, 1272 KJ Protein: 0.3g Carbohydrate: 82.4g Raisins: water 15.43g energy 299kcal, 1242kj protein 3.07g carbohydrate 79.18g Dried apricots: Water: 30.89g Energy: 241 kcal, 1009 KJ Protein: 3.39g Carbohydrate: 62.64g * The main purpose of this food is to provide a burst of energy for quick recovery between races, which is shown by the high carbohydrate content, and to provide energy for later races, with high energy composition. This makes this an ideal snack during a day of multiple racing, or between training sessions. This was also a successful outcome. 6) MEAL 2 - MACARONI CHEESE Macaroni: water 65.99g energy 141kcal, 590kj protein 5.77g carbohydrate 28.34g Cheese: water: 36.75g energy 403kcal, 1684kj protein 24.9g carbohydrate 1.28g Milk: Water: 89.33g Energy: 50kcal, 207 kJ Protein 3.3 g Carbohydrate: 4.63 kJ Breadcrumbs: water: 30g energy: 277kcal, 1159 KJ protein: 10.9g carbohydrate: 51.7g 1 ...read more.

    5 star(s)

    Lactose is a reducing sugar. It is formed from glucose and galactose which are linked by a glycosidic bond between carbon one of galactose and carbon four of glucose. The molecular formula of Lactose is C12H22O11. Sucrose, maltose and lactose are all disaccharide sugars.

    every fully formed fifth leaf from each branch will be picked and only juvenile ivy leaves will be used in the investigation. A sizeable sample of 30 leaves from each tree will be taken to obtain reliable results. The leaves will be measured along the midrib with a ruler and the measurements recorded in a table of results.

    Normally these ionic attractions require a large amount of energy to break, but when put into water, the negative oxygen side of the water molecules cluster around the positive sodium ions [Na+] and the positive hydrogen atoms cluster around the negative chloride ions [Cl-].

  2. What effect does substrate have on respiration in yeast?

    carbon dioxide and they are also needed to confirm that any results obtained will be reliable and unbiased. VARIABLES Independent variable is the factor that is being modified by the person carrying out the investigation. In this case, it would be the different substrates, two different monosaccharides and three different disaccharides will be used.

    I believe this is due to their being an increase in the enzyme therefore there are more enzyme active sites to react with the substrate hydrogen peroxide. This means that more collisions will take place, and therefore more oxygen and water will be released.
