How Does Nutrition Affect Athletic Performance Physical Education Essay

How Does Nutrition Affect Athletic Performance carnal Education EssayAthletes argon dedicated to their variant. They exercise daily, train with professionals, face lift weights, engage in team practices, and compete against one an another(prenominal). All this commitment is made in an effort to generate the world personate consummation more efficiently. Continuous exercise and nurture, conditions the ponderousnesss to work better alongside the bones. For example, baseball pitchers would want to train the brawns in the arm to throw a flagrant fast pitch, long distance runners would work to control the respiratory trunk in rules of order to finish strong at the end of an panoptic race, and football players build on agility and muscular resolution sequentially outrunning the opponent. The current generation of athletes has caused competition in sports to reach unprecedented levels. However, the impatient question remains, argon athletes consuming the right nutritions to fulfill their activities? Adequate pabulum is an integral aspect to gymnastic instruction execution. Athletes that demand a luxuriouslyer carrying out in their respective sport and pedagogy should pick up a naughty provenderal value in relation to their activities. It is small to maintain a balanced, vigorous diet at all times in order to achieve maximum performance. A good diet with becoming nutrition much(prenominal) as vitamins, minerals, protein and water in terms of the right-hand(a) gets of calories condescend activities.Athletes acquire readiness from the regimens they eat. Food nookie be further dual-lane into two categories macronutrients and micronutrients. Macronutrients bring an athlete with direct sources of vigor for daily life story activities and sensible exercise. Macronutrients complicate proteins, sugars, and risques1. Micronutrients aid in the figure outes of life, such as digestion and f ar metabolism. Although they be not able to provide efficacy, they atomic number 18 subjective in generating zero for the human forcible structure. Some examples of micronutrients are vitamins and minerals2.Protein is a macronutrient involved in many chemical processes of life. Proteins are specialized for different organs and species. Proteins are combinations of aminic panellings that combine in various ways to make energy, bones, tendons, fell and many other tissues. When proteins are broken conquer by the em system at ingestion, amino acids are formed. on that point are 20 amino acids which table service form human proteins, however only 9 are essential. Meaning 9 out of the 20 proteins are supplied by the sustenance we eat, because the human body is unable to produce them through synthetic processes in the cell. Protein is one of the components in body tissues, necessary for cellular growth and repair, as well as in hormones, enzymes, the immune system, and bodily fluids3. Athletes request protein ea rlier to repair and rebuild muscle that is broken down during somatogenetic exertion. work out breaks down muscle fibers and the body has to quickly rebuild those fibers for futurity performances. Through the process of abideoration the body synthesizes proteins. The muscle fibers broken down during training depart strengthen over time as adequate gists of protein are ingested to facilitate the growth process4. Protein is the last source of energy used when other macronutrients are available. When the body lacks adequate carbohydrates, the body turns to protein as a source of give notice for physical operation. During extreme physical activity, muscle tissue becomes an energy source because there is an insufficient amount of fat and carbohydrates involved. Therefore it is necessary to maintain an adequate protein intake eitherday, to make up for the protein anomic in the muscle tissue during an increase in lastingness or length of training5.Research has shown an amino ac id know as creatine, faeces help enhance athletic performance. Derived from other amino acids, glycine, arginine, and methionine, creatine is lined in the diminished muscle as creatine phosphate. The barter of creatine phosphate is to help facilitate the production of energy. With an increased store of creatine phosphate in the body, the ability to produce energy during high strong point training is improved. This is a result of muscles in the body that have the ability to store a greater amount of creatine than what athletes fine-tune from their diet. Athletes can obtain creatine primarily from meat and fish6.Carbohydrates are the primary displace for the exercising muscles and are essential for supporting the training and performance of an athlete. They are the major energy source for an aerophilic and aerobic activity. Carbohydrates are broken down into glucose molecules and stored in our skeletal muscles and liver as animal starch. The amount of animal starch stored pe rtains stamina and resolution. After an athlete is done training, glycogen is ignitiond from the liver into the storestream to restore the glucose levels in the derivation, and glucose is transported to cells for energy7. If the blood glucose levels are low, athletes may feel irritable, tired, and lack concentration, interfering with their performance. Glycogen stored in the skeletal muscles provides fuel for the exercising muscles during high and low-intensity activities. There are limited carbohydrate reserves in the body and exercising causes the glycogen stores to become drop very quickly. During exercise, if muscle cells run out of glycogen, the muscles lack energy and scare off sets in. Performance suffers accordingly, but allow vary depending on the sport and its intensity8. Therefore, daily carbohydrate inspiration and training is necessary to maintain glycogen for optimal performance. In order for athletes to obtain enough energy to increase athletic efforts, carbo hydrates also aid in fat metabolism. The presence of carbohydrates is essential in utilizing fat for energy, associating with the old saying, fat must burn in a carbohydrate flame9. Increased fat-burning helps to conserve carbohydrates in the muscle, whence the stored up amount is used to support athletes in later activities10. In general, endurance athletes use up more carbohydrates than athletes that use carbohydrates for strength and power. This is because endurance athletes are participating in physical activity over a longer period of time, meaning a greater amount of carbohydrates is need by the body to supply it with energy over the duration. On the other hand, athletes involved in strength and power events require fewer amounts of carbohydrates to supply a sudden burst of energy for powerful, but short-lived physical activities11. Adequate intake of carbohydrates will prevent the body from extracting other macronutrients from their desire jobs to become fuel for activity. Ideal sources of carbohydrates take whole-grain cereal, pasta, brown rice, and brown plunder products. As part of a wellnessy diet, athletes should include at least(prenominal) two carbohydrate-rich foods accompanying each meal, and at least one with both snack12.Prior to competitions, athletes like to load muscles with glycogen to delay put on that occurs during endurance events. A diet that contains highly nutritious carbohydrates, covering 55-65% of aggregate calories, is sufficient enough to provide adequate glycogen repositings that will help support the athlete over the duration of their performance13. exposit is the dominant fuel source during prolonged exercise. The body has an unlimited storage power for fat, making it the largest reserve of energy in the body. It is integral for many metabolous processes such as energy production, synthesis of vitamin D, cholesterol, hormones, and transporters of lipid soluble vitamins. Fat can be classified into two categories b ased on its structure unsaturated and saturated fats. Unsaturated fats are obtained from plant sources. Advantages of unsaturated fats include lowering cholesterol and reducing the risk of heart disease. Saturated fats on the other hand, come from animal sources and cheese. Saturated fats are not recommended in large consumption to athletes, because an purposeless of this macronutrient will raise cholesterol and/or lipid levels in the blood which can lead to the development of heart-related diseases14. However, fats do hold a place in sports nutrition. Fats are less type O-rich, and they can release a greater amount of energy at a greater speed than other nutrients. This can provide an athlete with a concentrated source of energy. Fat is essential for longer and lower intensity, endurance exercise. another(prenominal) role that fats play in the human body is insulation. Fats countenance in insulating and protecting vital organs and parts of the body15. Athletes can obtain fat fro m food sources such as milk, butter, meat and oils16. Athletes need to keep in mind to carefully monitor the type and the amount of fats they eat.Vitamins are essential micronutrients athletes need to produce energy. Vitamins mostly come from the food we eat, with the exception of vitamin D. Instead of participating in the metabolic processes of nutrients, vitamins help to bilk the reactions in metabolic processes. They are responsible in facilitating energy release and synthesizing bone and tissue. Absence of a vitamin prevents certain metabolic processes from occurring in the cell, which ultimately affects the metabolic balance in the body, as a whole17.Another micronutrient occurs naturally on earth. It is found in the water, soil, and the plants of Earth. This micronutrient is known as the mineral. There are seven key minerals calcium, potassium, phosphorous, magnesium, sodium, chloride, and sulphur. Two minerals that are important for athletes are iron and calcium. Iron is a main component in the blood. It is critical for red blood cell formation, function and myoglobin composition. Iron operates in the blood as an oxygen carrier, a key role in sport performance. If iron levels are low in athletes, they can develop fatigue, abject appetite and an increase in resting pulse rate. This occurs because an insufficient supply of oxygen is distributed to parts of the body. Oxygen combines with glucose to form ATP molecules, the main source of energy for the muscles. The greater amount of ATP stored in the muscles, the more powerful they will be when it performs work. start iron levels in the blood mean that muscles do not receive enough oxygen to support exertion. This results in lactic acid being produced and the athlete endures pain and fatigue in the muscles. However, excess amounts of oxygen in the body help athletes to metabolize lactic acid back into useful energy molecules after exercise. This allows the muscles of athletes to recover faster and be ab le to carry out physical activity again without having to rest for long periods of time. Iron can be obtained from many food sources, such as cereals, red meats, and bread products18.When athletes want to develop stronger bones, they need to consume calcium in their diets. Calcium is a micronutrient from the popular dairy food group, comprised of milk, yogurt and cheese. Ninety-nine percent of the calcium in our body is stored in the skeletal system, while the remaining one percent is accumulated in the muscle cells19. When muscles are at work, calcium ions are released to trigger muscle contraction. Calcium ions are released into the sarcoplasm and then they find their way to attach onto the troponin molecules. Without the shackle of troponin molecules and calcium, the interaction of actin and myosin leading to muscle contraction will not occur. Thus, if muscle contractions are not generated, athletes are unable to perform their activity20. Low calcium levels in the body are in r elation to ontogeny low bone density. This causes the bones of the body to become more soft and vulnerable to stress fractures, as the limiting amount of calcium will be used for muscle contraction. Therefore in order for athletes to halt intense physical activity, an adequate amount of calcium is essential in their meals21.Finally, athletes need to stay hydrated for optimal performance. The human body consumes energy during physical exercise and creates heat. Bodily temperature would rise drastically causing the body to overheat, if heat was not released. In conjunction with the release of heat, the bodys sweat glands discharge fluid to the surface of the skin, where it eventually evaporates. This overall process occurs in an effort to cool the body. However, this leaves the body dehydrated22. peeing comprises 50-60 percent of the weight of human bodies23. This portion of water in the human body helps to regulate heat and maintain a constant body temperature. Water helps to tra nsport nutrients to cells and extract waste products. Water distributes the heat generated by physical activity throughout the body and enables the body to perspire. Fluids, not just water, are lost when humans perspire, urinate, defecate, and respire. A constant replacement of fluids is necessary for the human body to continue to operate and achieve its optimal performance. Research has shown that when athletes sweat, they pull back 1-2% of body weight which is linked to a decrease in blood volume. This process causes the heart to work harder to circulate the blood, resulting in muscle cramps and silliness24. Athletes establish proper hydration by drinking the right fluids during physical activity. This pith drinking fluids properly throughout the day when thirsty, and especially before an activity begins. In the course of a long competition, where fluid is being lost in sweat, sport drinks are good sources of electrolytes. The sodium levels in the drinks are ideal replacements o f sodium secreted in sweat. Low sodium levels can affect concentration. In general it is not advised for athletes to drink sport drinks such as Gatorade, on a regular basis or every time they participate in physical activity. These fluids can interfere with the body absorbing the proper nutrients and encourages thirst in the individual25.The principle that underlies healthy eating and enhancing sports performance is maintaining a balance between food consumption and the amount of energy that is going to be used for work. Since athletes participate much in physical exercise, they will need to absorb more energy in the foods they eat. The following principle is expressed as an energy equivalence Energy storage = Energy intake Energy output. Energy storage represents the amount of energy left in the body after the amount of energy used is reduced from the amount of energy taken in by the body. If athletes absorb insufficient amounts of energy from food sources, optimal performance w ill not be achieved. Muscles will weaken without nutrients and negative health effects become a concern for athletes26.Athletes spend many hours training and undergoing physical activity so the body can excel in sports performances. It is important that athletes keep their bodies nourished in order to supply fuel for athletic endeavours. Athletes need to develop a focus on maintaining proper nutrition, so the hours spent during physical activity and rest are not subjected to waste. Good nutritional habits are necessary to achieve optimal physical performance, however it does not mean that we should categorize foods as good or bad. To maintain a healthy lifestyle, athletes should consume foods from various food groups and make better food choices at the same time. Daily food choices should include macronutrients such as protein, carbohydrates, and fat, micronutrients such as vitamins and minerals, and most importantly fluids, such as water. Athletes are better equipped to meet their maximum athletic potential if the right foods are taken in the right amounts to fuel the body. Great athletic accomplishments are determined by great nutrition.
