THE RIGHT BALANCE Just as a car runs best with a full gas tank, your body needs the right kind of «nutritional fuel» for peak performance. Eating well for 89 your sport can be very simple. You do not need special foods or supplements. It is important to fuel your body with a balance of carbohydrates, proteins, fats, minerals, vitamins, and water. Carbohydrates (found in pasta, bread, cereal, rice, potatoes, fruits, milk, yogurt, etc.) are especially important for athletes because they supply the body with glucose (blood sugar) for energy. Extra glucose is stored in the muscles and liver as glycogen. During short bursts of exercise such as sprinting, basketball, gymnastics, or soccer, your body primarily uses glycogen for energy. If you don’t have enough glycogen you can feel very tired, which will affect your athletic performance. During longer exercise, your body uses the glycogen stores first and then uses fats stored in your body to fuel performance. Fat is an important source of energy used to fuel longer exercise and endurance activities, such as hiking, cycling, and long-distance running. Eating a diet that is too low in dietary fat may decrease athletic performance and cause other health problems. Protein is needed for your body to build and repair muscles. Small amounts of protein may also be used for energy. Vitamins and minerals are not sources of energy, but they have many important functions in the body. For example, vitamin D and calcium are needed for strong bones, and iron is needed for blood cells to carry oxygen throughout your body. Certain minerals, like potassium, calcium, and sodium are called electrolytes. They are important during exercise because they affect the amount of water in your body and muscle activity. Athletes should eat a balanced diet with a variety of foods to make sure they get enough vitamins and minerals. It is fine to take a regular multivitamin, but supplements with high doses of vitamins and minerals do not improve performance and may actually be harmful. Water is essential to keep you hydrated (when your body has enough fluids). Dehydration (when you don’t have enough fluids) can cause muscle cramps and keep you from performing your best. 2. Answer the questions. 1. Why do athletes need the right balanced nutrition? 2. What are the main organic compounds that should be present in the right balanced nutrition? 3. What products contain carbohydrates? 4. Why it is important for athletes to have an adequate amount of carbohydrates in their diet? 5. What can happen if you do not have enough glycogen? 6. What cause the reduction of athletic performance? 7. Should the athletes enrich their diet with vitamins and minerals? Why? 8. What substance keeps us hydrated?
Willard Wigan (born in 1957 in England) is the creator of the smallest works of art on Earth! His miniature sculptures include The Titanic on a pinhead, a cat on an eyelash and the six wives of Henry VIII in the eye of a needle. Some art a lot smaller than the full stop at the end of this sentence.
Wigan started making tiny things when he was a child. People made him feel small because he had learning difficulties, so he decided to show them how significant small could be! How does he create his unbelievable micro-sculptures? He slows his breathing, then patiently sculpts or paints between heartbeats, so that his hand stays perfectly still. He spends months carving his tiny creations from materials such as toothpicks, sugar crystals and grains of rice and then paints them with a tiny hair such as an eyelash. So how do visitors to Willard Wigan's exhibitions view his work? Through a microscope, of course!
Растительная пища необходима для хорошего здоровья и обеспечивает жизненно важные функции организма котов и собак.
Известно, что вареной (термически обработанной) пищи недостаточно.
Витамины В содержатся в зелени. В целом, витамины играют важную роль в метаболизме и участвуют в ферментной системе и других важных для хорошего здоровья процессах и они гарантируют правильное жизненное функционирование котов и собак. Недостаток или отсутствие витаминов вызывает авитаминоз. Дефицит витаминов В-группы вызывает патологии центральной нервной системы котов и собак. С тех пор как у животных возросла потребность в витамине В, владельцам следует постоянно обеспечивать их достаточным количеством витаминов. С этой проблемой легко можно справится путем добавления свежей зелени (травы) в пищу.
