| The Importance of Water: Other cold drinks such as milk, soft drinks, fruit juices and energy drinks may seem like they quench your thirst, but the feeling is only temporary, they will in fact actually increase your need for water. The importance of water is unquestionable, more so for someone who is physically active. As the major ingredient of the human body, an adequate daily supply of water is essential to both healthy living and athletic performance. The average person loses approximately 2.5 percent of their total body water per day. When you participate in events above and beyond normal activities, like exercise, sporting events, or even yard work, the risk of dehydration is even greater. Any activity that causes you to sweat depletes your body fluid levels. Strenuous activity will have an even greater effect and quickly dehydrate the system. Dehydration is the loss of water from the body, and a depletion of electrolyte levels (sodium and potassium). When you become dehydrated even slightly, your body fights back by slowing down the elimination of water. In the event that this occurs, you retain excess amounts of water. A restriction of fluids virtually stimulates your body to retain more water. Dehydration is treated by replacing the water the body is lacking and by restoring electrolyte levels back to normal. Dehydration may be caused by inadequate water intake or by excessive water loss, but the most common cause of dehydration is a simple failure to drink liquids. When working out, rather than drinking large quantities of water at once, take a few sips between sets even if you don’t feel thirsty, because by the time you do feel thirsty, you are already dehydrated. |
| Vitamins: Vitamins are any of various relatively complex organic substances found in plant and animal tissue and required in small quantities for controlling metabolic processes. Everyone needs vitamins, and active people need more vitamins than sedentary people. If you want to be successful in achieving peak performance capabilities, you need to provide your body with everything it needs. Vitamins are undoubtedly essential to physical performance. Each of the vitamins has a specific responsibility in your body. Here are the most important vitamins essential to successful physical performance. VITAMIN A (RETINOL) - Fat-soluble. Vitamin A is stored in the liver and helps maintain healthy teeth, bones and soft tissue. It reduces susceptibility to infections by protecting the mucous membranes of the mouth, nose, throat and lungs, and contributes to the function of night vision. Excess vitamin A intake can be toxic, due to the fact this vitamin is fat soluble. Vitamin A can be found in carrots, kale, liver, spinach and broccoli. VITAMIN B1 (THIAMIN) - Water-soluble. Vitamin B1 is essential for the normal functioning of the nervous system, muscles and heart. It also stabilizes the appetite and promotes growth along with good muscle tone. More than 1000 milligrams of B1 might cause increased urination and possible dehydration. Because this vitamin is water soluble, daily replacement is necessary. Whole grains are the best source of B1, also beef, kidney, liver and brown rice. VITAMIN B2 (RIBOFLAVIN) - Water-soluble. An active agent in the metabolism of energy and cell maintenance. It also is an essential ingredient in the repair of all cells following injury. In addition to producing energy for the body, riboflavin also works as an antioxidant which means it helps the body deal with unstable chemicals called free radicals. Milk and eggs are excellent sources of vitamin B2. VITAMIN B3 (NIACIN) - Water-soluble. Niacin plays an important role in removing toxic and harmful chemicals from the body. It also helps the body make various sex and stress-related hormones in the adrenal glands and other parts of the body. Niacin helps to maintain the central nervous system and is also effective in improving circulation and reducing cholesterol levels in the blood. It also helps maintain a healthy skin, tongue and digestive system and prevents pellagra. Pellagra is the name given to the medical condition that results from a lack of niacin and symptoms include weakness, sore mouth and irritability. Niacin requirements can be partially met by eating foods containing protein because the human body is able to convert tryptophan, an amino acid, into niacin. Chicken, peanuts, sardines and tuna are fine sources of Vitamin B3. VITAMIN B5 (PANTOTHENIC ACID) - Water-soluble. Vitamin B5 is critical to the manufacture of red blood cells as well as sex and stress-related hormones produced in the adrenal glands (small glands that sit above the kidneys). It is not only essential for the synthesis of hormones but also cholesterol and helps in cell building and the development of the central nervous system. Vitamin B5 is also important in maintaining a healthy digestive tract and it helps the body use other vitamins (particularly riboflavin) more effectively. It is somemtimes referred to as an "anti-stress" vitamin because it is thought to enhance the activity of the immune system and improve the body's ability to withstand stressful conditions and fights infections by aiding the process of building antibodies. Good sources of Vitamin B5 are to be found in Poultry, fish, whole grains, eggs, milk, broccoli, yeast, lean beef. VITAMIN B6 (PYRIDOXINE) - Water-soluble. Vitamin B6 is important for the maintenance of the central nervous system and muscle cells. Furthermore, it aids in the removal of excess fluid of premenstrual women. It aids the production of DNA and RNA, the body's genetic material and assists the formation of antibodies in the immune system. It reduces muscle spasms, leg cramps, hand numbness, nausea and stiffness of hands, and promotes healthy skin. Vitamins B12, B6, and B9 (folic acid) work closely together to control blood levels of the amino acid homocysteine. Elevated levels of this substance appear to be linked to heart disease. Vitamin B6 is also essential for normal brain development and function, since it aids the process of making important brain chemicals called neurotransmitters. Vitamins B6 also helps the balance of sodium and phosphorous in the body. It can be found in foods like wheat germ, rice, fish, walnuts, bananas and avocados. VITAMIN B12 (COBALAMIN) - Water-soluble. Vitamin B12 is an important vitamin for maintaining healthy nerve cells and it aids in the production of DNA and RNA, the body's genetic material. It also works closely with vitamin B9 (Folate) to regulate the formation of red blood cells and to help iron function properly in the body. Furthermore, vitamin B12 is needed for Calcium absorption. Deficiencies of vitamin B12 are usually caused by a lack of intrinsic factor, a substance that allows the body to absorb vitamin B12 from the digestive system. Such a deficiency can cause a range of symptoms such as fatigue, shortness of breath, diarrhea, nervousness, numbness or tingling sensation in the fingers and toes. People with the blood disorder pernicious anemia do not produce sufficient intrinsic factor and must take high doses of vitamin B12 to maintain their health. Others at risk for B12 deficiency include vegetarians who follow a strict vegan or macrobiotic diet. Good sources of Vitamin B12 include liver, oysters, clams, beef, blue cheese, eggs, mackerel and sardines. VITAMIN B15 (PANGAMATE OR PANGAMIC) - Water-soluble. A coenzyme involved in respiration, protein synthesis, and regulation of steroid hormones. Its principal effect is to increase blood and oxygen supplies to tissue. Deficiency states produce no apparent negative effects, which lead some conservative nutritionists to the conclusion that it is not a true vitamin. Research suggests that B15 may assist the lowering cholesterol blood levels and aid in protein synthesis. Vitamin B15 has also been used to treat cancer, schizophrenia and heart disease. Good sources of vitamin B15 are to be found in seeds, nuts, brown rice, brewer’s yeast, pumpkin seeds and sesame seeds. VITAMIN B17 (LAETRILE OR AMYGDALIN) - Although Vitamin B17 is called a vitamin, it is not generally recognized as dietary vitamin. It is touted as an ingredient which can prevent the growth of cancers, but has been outlawed for sale in many countries. It has been reported that Laetrile helps with reducing blood pressure and the pain associated with arthritis. Good sources are to be found in apricot kernels, stone fruit kernels and sprouting seeds. VITAMIN C (ASCORBIC ACID) - Water-soluble. Vitamin C promotes healthy cell development and proper calcium absorption. Large amounts of vitamin C are used by the body during any kind of healing process from an infection, disease, injury, or surgery. It also helps to repair and maintain healthy cartilage, bones, teeth and gums and assists in the prevention of blood clotting and bruising. It is required for the synthesis of collagen, the intercellular "cement" which holds tissues together and is used to make skin, scar tissue, tendons, ligaments, and blood vessels. Furthermore it prevents scurvy, builds resistance to infection and aids in the prevention and treatment of the common cold. Good sources of Vitamin C include leafy green vegetables, citrus fruits, tomatoes, melons and berries. VITAMIN D (CALCIFEROL) - Fat-soluble. Vitamin D is also known as the "sunshine vitamin," since it is manufactured by the body after being exposed to sunshine. Ten to fifteen minutes of sunshine three times per week is sufficient to produce the body's requirement of vitamin D. The liver and kidneys convert vitamin D from food sources or sunlight to its active form, calcitriol. Vitamin D is essential for building and maintaining healthy bones because it helps maintain healthy levels of calcium and phosphorus. Vitamin D and calcium are involved in many body functions, including keeping the immune and nervous systems healthy. Calcium is also the principal element in bone, and can only be absorbed by the body when vitamin D is present. Rickets, a vitamin D deficiency disease responsible for softening and weakening bones in children, used to be quite common but is now quite rare in countries that have adopted the practice of fortifying milk products. Sunlight serves as the best source of Vitamin D, but also found in sardines, salmon, tuna, liver and egg yolk. VITAMIN E (TOCOPHEROL) - Fat-soluble. Vitamin E is present in many foods, especially certain fats and oils. Vitamin E is also useful in preventing blood clots from forming. It promotes fertility and it reduces and prevents hot flushes in menopause. Vitamin E is also used as a skin treatment to help the skin look younger, promoting healing and cutting down the risk of scar tissue forming. Used on the skin it is also reported to help with eczema, skin ulcers, cold sores and shingles. Vitamin E is also essential for red blood cells and helps with cellular respiration and can increase stamina and endurance. Vitamin E is a fat-soluble vitamin. A fat-soluble vitamin dissolves and remains in the fatty tissues of the body, reducing the need to ingest large quantities. As such symptoms from a defiency in fat-soluble vitamins may not be apparent for years. They should not be consumed in excess unless under strict medical supervision since toxic reactions from fat-soluble vitamins occur at a smaller percentage of the RDA than water-soluble vitamins. Good sources are to be found in nuts, oils, spinach, sunflower seeds and whole grains. VITAMIN K (PHYLLOQUINONE) - Fat-soluble. Vitamin K can be produced in the intestines and this function is improved with the presence of cultured milk, like yogurt, in the diet. Vitamin K is found in nature in two forms - K1, also called phylloquinone, is found in plants and vitamin K2, also called menaquinone, which can be synthesized by many bacteria. Vitamin K3, menadione, is a synthetic form of this vitamin which is manmade. Vitamin K is used in the body to control blood clotting and is essential for synthesizing prothrombin a precursor to the liver protein, Thrombin that controls the clotting. In the intestines it also assists in converting glucose to glycogen, this can then be stored in the liver. There are some indications that Vitamin K is also involved in bone formation and repair and may decrease the incidence or severity of osteoporosis and slow bone loss. Good sources are to be found in leafy vegetables, cheese, liver, asparagus, coffee, bacon, green tea and beans. |
| Minerals: Minerals play a very significant role in various bodily functions essential to physical movement. A deficiency in any mineral can be disastrous to peak performance. Minerals are naturally occurring homogenous inorganic substances with a specific chemical composition and characteristic crystalline structure. For example, failure to consume adequate levels of calcium or iron can result in fatigue, weakness and injury. Women tend to be more likely to experience such deficiencies than men. Minerals are found in plants and animal foods along with your drinking water. Many times the quantities of minerals found in these sources are too small. Since the stresses associated with sport activity promote the loss of various minerals. It becomes more important to increase your mineral intake. Here are some of the minerals most important to physical performance. CALCIUM: Calcium is the most abundant mineral in the body. It is essential for the development and maintenance of strong bones and teeth; roughly 99% of calcium in the body is deposited in these two places. It is necessary for blood clotting, stabilizes many body functions. It can ease insomnia and is necessary for maintaining a regular heartbeat and the transmission of nerve impulses. Calcium regulates heart rhythm and the passage of nutrients in and out of the cell walls. It helps with lowering cholesterol, muscular growth, the prevention of muscle cramps and normal blood clotting and may reduce the incidence of colon cancer. Calcium also stops lead from being absorbed into bone. To function correctly, calcium must be accompanied by several other nutrients including magnesium, phosphorous, and vitamins A, C, D, and K. The best sources of calcium are foods, but supplements may be necessary for those who cannot meet their calcium needs through diet alone. In fact, according to the National Institutes of Health, many Americans consume less than half the amount of calcium recommended to build and maintain healthy bones. Heavy use of caffeine can diminish calcium levels; therefore, higher amounts of calcium may be needed if you drink a lot of coffee. Also, a diet high in protein can increase loss of calcium through the urine. Excessive intake of sodium, phosphates (from carbonated beverages) and alcohol, as well as the use of aluminum-containing antacids also contribute to increased excretion of calcium. Calcium deficiency can be found in people with malabsorption problems, such as Crohn's disease, celiac disease, and surgical intestinal resection. Prolonged bed rest causes loss of calcium from the bones and the elderly are less able to absorb calcium. Milk, beans, nuts, fish and green leafy vegetables are all great sources. CHLORIDE: Chloride works with potassium and sodium to regulate the flow of fluid in blood vessels and tissues, and to regulate the acidity in the body. It is also present in the stomach as hydrochloric acid. Increased intake of chloride in the form of salt can cause fluid retention, but this is primarily because of the sodium in the salt, not the chloride. A deficiency of chloride can be caused by fluid loss as a result of excessive sweating, vomiting, or diarrhea. Use of medications such as diuretics can also cause a deficiency. Kelp, olives and tomatoes are great sources of Chloride. COPPER: Copper helps to convert iron to hemoglobin and promotes the use of vitamin C. Most foods have copper in them. IRON: Iron is essential in making hemoglobin or oxygen in your blood and crucial in the transportation of oxygen during endurance activities. An intake of more than 50 milligrams a day for prolonged periods can be toxic. Coffee and tea consumption can limit the absorption of iron. The best source of iron is meat. even cooking in an iron skillet can increase the iron content in your food. MANGANESE: Manganese is a mineral essential in numerous functions including glandular secretions, the metabolism of protein and brain function. Too much manganese can inhibit the absorption of iron. Food sources are tea, leafy green vegetables and whole grains. MAGNESIUM: Magnesium plays an important role in regulating the neuromuscular activity of the heart. Where calcium stimulates the muscles, magnesium is used to relax the muscles. It aids the formation of bone and teeth and assists the absorption of calcium and potassium. Magnesium maintains normal heart rhythm and is needed for cellular metabolism and the production of energy through its help with enzyme activity. It also assists the parathyroid gland to process vitamin D, and a shortage here can cause absorption problems with calcium. Good sources are found in fish, apples, bananas and whole grain cereals. PHOSPHORUS: Phosphorous is involved in bone and teeth formation as well as metabolism, kidney function, cell growth and heart muscle contraction. It not only helps in conversion of food to energy (it is crucial in the production of ATP, a molecule the body uses to store energy) but also in vitamin utilization particularly with the B-vitamins. Cell membranes are composed largely of phospholipids. The inorganic constituents of bone are primarily a calcium phosphate salt called hydroxyapatite. Good sources are found in meat, fish, eggs and milk. POTASSIUM: Potassium works with sodium to regulate the body's waste balance and normalize heart rhythms. It is needed for many functions such as growth, building muscles and transmission of nerve impulses. Potassium is lost in excessive sweating and urine and so foods like bananas are important for sports. Furthermore, if you are suffering from vomiting or diarrhea you may require more potassium. It preserves proper alkalinity of body fluids and assists in reducing high blood pressure along with promoting healthy skin. Potassium also stimulates the kidneys to eliminate poisonous body wastes. Bananas, fish and whole grains all carry good sources. SODIUM: Sodium is essential in the production of hydrochloric acid in the stomach which protects the body from food infections. It is a component of salt; table salt is 40 percent sodium and 60 percent chloride. Sodium has an important role in maintaining the water balance within cells and in the function of both nerve impulses and muscles. Any extra sodium is excreted by the kidneys. Consuming excess sodium may lead to edema or water retention. Women who consume excess sodium may be at higher risk for developing osteoporosis even if calcium intake is adequate. Sodium intake is one factor involved in the development of high blood pressure, otherwise known as hypertension. Athletes are sometimes concerned about not getting enough sodium to replace what is lost through perspiration. Kelp, olives and tomatoes have great sources. ZINC: Zinc is responsible for cell growth by acting as an agent in protein synthesis. Also aids in the use of vitamin A and B-complex vitamins. It prolongs muscle contractions and therefore increases your endurance. Sources include eggs, whole grains and oysters. |
