The Importance Of Sports Nutrition To Athletes

August 23rd, 2010

Almost all of the people, occupying this world, dream of being a sports superstar. You long for that feeling when thousands of fans scream your name when you are about to win a game. But unfortunately, only those with extreme discipline, hard work and talent get to experience that.


Talent is not the only secret of being a sports icon, it is also the way they get their nutrition. You see, sports nutrition is different from normal nutrition because with sports nutrition, the athletes require more nutrients to keep their energy up during their various activities. Athletes perform strenuous activities, that is why more nutrients are needed to keep them running.


Athletes lose a lot of fluids during their game. And like everyone knows, dehydration is one of the biggest problems in the athletic world. Getting tired and thirsty will affect an athlete’s performance, just as it affects anyone else’s, except that it makes the life of an athlete a lot more difficult to live.


Everyone knows that an athlete’s performance is the reason why they get paid, seriously. So basically, if you are an athlete and you want to have that winning edge, then you better get that right nutrition. When you drink enough water and eat a balanced diet and also get the right sports nutrition, your body can utilize energy efficiently and also fuel top performance.


You can make the most of your athletic talents and have more strength, power and endurance when you get the right sports nutrition. These are not just for boasting purposes, however, athletes do have their own way of boasting the above mentioned attributes.


Your diet should be based on different factors and this should involve your age, size, physical condition and the type of sports you are engaging yourself in.


You should first consult your doctor about your diet and not just decide one for yourself. They have the license and they are extremely professional at it, which is why they can give you the right advice on your proper diet and nutrition that you should have.


You lose a lot of fluids every time you exercise. Just imagine the gallons of sweat you lose when you are pumping that body of yours. That is why water is the most important factor in sports nutrition. It is not the only factor, but in truth, it is the most important.


It makes up about sixty percent of your body weight and is involved in almost all of your bodily processes.


As you probably already know, your body cannot produce and store water, this serves as the main reason why you should replace all fluids that you eliminate while doing your exercise, or else you will have to suffer being dehydrated. With athletes, they require more water than the normal eight glasses a day.


Drink plenty of fluids before, during, and after any kind of sports activity to prevent over-heating and dehydration. At least try to drink the same amount of water you lose due to sweat. There are also various sports drinks that are good for longer events. Getting hydrated will definitely help boost your energy.


Eating a balanced diet is another key to sports nutrition. The right combination of calories from carbohydrates, proteins and fats gives you more energy for top performance. These nutrients perform certain actions that will help your body as you perform strenuous kinds of sports.


Carbohydrates are the most important fuel source. It provides a minimum of sixty to a maximum of seventy percent of our calories. Carbohydrates are found on almost all of the food you consume. Food rich in carbohydrates are fruits, vegetables, pastas, breads, cereals, rice and many more that are too many to mention.


Your body converts sugar and starches from carbohydrates to glucose, which is the main source of energy of the body. Your body also stores the glucose into your liver and muscles giving your body a reservoir of energy. The more carbohydrates you have, the more energy you can give out. If you run out of carbohydrates, you can also get energy form proteins and fats.


You can get your proteins from meat, fish, poultry, eggs, beans, nuts, dairy products and other foods. Proteins provide a minimum of fifteen to a maximum of twenty percent of your daily calories. They are used in tissue and muscle build up.

Sports Nutrition – Changing Through The Years

August 23rd, 2010

Advancements in medicine and an increase in capitalism in the world as well as other factors all contributed to the development of the field of sports nutrition.


As scientists learned more and more about our bodies and the optimum level of strength and physical fitness they can harbor, businessmen jumped the gun and manufactured products and services that actually help athletes meet these optimum levels. The media joined in the ruckus and published materials leading to the promotion of both the scientific and the commercial side of the field.


Sports nutrition has been changing through the years around the world. It’s not just that the topics are different; the emphasis and approach have also changed.A sports magazine carried an article on dehydration in runners on October 1990, its maiden issue. This article compared the benefits of plain water with those of dilute glucose solutions, which are more isotonic and therefore absorbed more rapidly.


Today, go into almost any supermarket, convenience stores and even school cafeterias and you’ll find a ready supply of sports drinks aimed at maintaining hydration just like glucose solutions.


The difference is that by using soluble long-chain glucose polymers instead of simple glucose, it’s now possible to create an isotonic hydrating drink which also supplies significant amounts of carbohydrate to working muscles. And, the good thing is, sports drinks also taste better.


More than 10 years ago, it was made public that muscle damage brought about by free-radicals may be reduced by having supplements of antioxidant vitamins A, C and E. Years after, antioxidant supplementation became a norm in the world of sports nutrition.

Now, researchers are also beginning to understand that muscle damage is a more complex subject. It is difficult to assess free radical damage in athletes and it has been found out that large amounts of antioxidant nutrients may actually cause cellular damage and impair performance.


The “Carbo loading” technique has been widely used over the years by athletes all over the world. A carbohydrate-rich diet is important in maintaining muscle glycogen stores thus ensuring high endurance levels.


However, in the 1990s it became clear that the “glycaemic index” and release rate of different carbohydrates had important influence on when they should best be consumed in relation to physical activity.


The relationship of carbohydrates and proteins were also discovered namely that carbohydrates promote protein-sparing in the body. It was also discovered recently that consuming carbohydrates before and during prolonged bouts of strenuous exercise can help protect the immune system.


One of the most exciting recent developments in sports nutrition has been the rise of creatine supplementation. The use of creatine is now very common. Creatine renews the muscles essential energy source, ATP or adenosine triphosphate. Increased levels in muscles optimizes energy turnover meaning you’ll more energy for high power exercise and faster recovery during and after workouts. Creatine also increases the athlete’s maximum effort, delays fatigue and therefore prolongs endurance.


New wisdom and therefore new products have definitely enabled athletes to fuel themselves better, work harder, train longer and recover more rapidly. However, as in any kind of innovation there will always be downsides.


Nutritional supplements available to most athletes in the 80s were very straightforward. Some athletes took drugs but the boundaries between nutritional supplements and drugs clear. Today, the race to find new formulas to boost performance has resulted to the availability of sports nutrition supplements which do not really occur naturally. The result is that the distinction between a nutrient and a performance-enhancing substance has become increasingly blurred.


Some of these supplements contain ingredients that can cause athletes to violate the rules and regulations governing their sport because of unintentional contamination by other, “exotic”, substances present in the supplement manufacturing environment.


More developments will be created in the world of sports nutrition and these will definitely spawn ethical questions. “Nutrigenomics” – the relationship between genetics and nutrition – will be more researched upon.


As scientists become more skilled at discovering the processes of our genes, it will be possible that rather than adopting a general approach for sports nutrition, athletes around the world will be genetically tested to help them determine precise individual requirements for optimum health.The following years will predictably be more exciting for the world of sports nutrition.

Sports Nutrition Guide For Women

August 22nd, 2010

Women have an entirely different body system compared to males. That is why your, assuming you are a woman with interest in sports, nutritional needs are different too. And like men, women are also capable of involving themselves in sports.


Sports nutrition for women is also different. Women involved in sports and regular exercise have some special nutritional needs. Although the basic principles of sports nutrition for you and men are similar, you, and the other women, involved in regular sports activities do have some increased needs for certain nutrients.


This is because you are prone and at risk of dietary deficiencies. This does not mean to say that men are completely immune, only that since women have ongoing cycles inside their body, it is highly imperative for them to keep nutrients up to be able to prevent disorders.


The key nutritional issues in sports nutrition for women include calcium and iron. Weight control and eating disorders are also concerns of sports nutrition for women. You need these nutrients for their body to perform properly.


There still has been no scientific explanation for this, but it is in truth that women are very conscious of weight. So having a normal weight will give you a healthy psychological system.


Calcium is a mineral that plays an essential role in growth. In sports, muscle and mind coordination is important. It also helps in muscle contraction and transmission of nerve impulses.


Another area where it is very helpful is in the development and maintenance of strong bones. It will really play a big part in the sports nutrition for women.


Having adequate amounts of calcium during your childhood and adolescence is important for deveoping an optimal peak in bone mass by your mid twenty’s to your early thirty’s. This will then help you reduce your risk of acquiring osteoporosis or the thinning of your bones.


Some women who are into sports are at risk of inadequate calcium intake, while some are at risk of early osteoporosis due to the absence of appropriate amount of calcium, or an irregularity of their menstrual cycle. So conclusively, sports nutrition for women should have higher intakes of calcium.


There is a list of recommended dietary intakes of calcium for sports women according to their ages. For girls with ages twelve to fifteen, they must have at least one thousand milligrams of calcium per day. For teenagers with ages sixteen to eighteen, on the other hand, should have a normal calcium intake per day, which is eight hundred milligrams. For women who are having their menstrual periods, they should also take eight hundred milligrams of calcium a day.


Post menopausal women should have at least one thousand milligrams per day of calcium, while women who are pregnant and who are also breastfeeding should have one thousand two hundred milligrams per day.


And, not to be the least, sportswomen who have an absent or an irregular menstrual cycle, they should have at least one thousand to one thousand five hundred milligrams in a day. It is detrimental for women to meet their required calcium intake for normal functioning.


The mineral iron is used in forming hemoglobin, which is essential in holding the oxygen in the blood as they are being transported to various parts of the body. It is also an essential nutrient for energy production and immunity.


Athletes are more prone to iron deficiencies than anyone else in the world. Women are at a bigger risk because they continually lose blood as they undergo the cyclical process of menstruation. Plus, strenuous exercises contribute to the loss of iron through the destruction of red blood cells. Inadequate iron intake are associated with reduced athletic performance. Sports nutrition for women require iron in big amounts.


Keeping your body’s fat levels low is the aim of many female athletes. Excess fats may be detrimental to performance. However, less fat or no fat at all compromises the energy level of a female athlete. Low energy also affects your performance, so it is really important that you keep the nutrients in your body and follow sports nutrition for women for a performance of a superstar that you have long been searching to experience.

Importance Of Nutritional Health in Sports

August 20th, 2010

Nutritional health is very important. The nutrients that we take in are practically the reasons why we are healthy or why we are not. It could also be a grid to determine if we can eventually become sports superstars or not. Nutritional health may be the main reason why you are tall, strong and have the skills to be good in sports. This is also vital for having a strong mind and a healthy body because of the fact that these nutrients fuel almost all bodily functions.


In reality, many people fail to achieve a high level of nutritional health. Some reasons why they are not adequately nourished is because of their lack of information. Some people do not even know that what they are eating is bad for them. Some food also lack nutritional facts that they should have on their labels. And some just do not care at all.


People also have this misconception that what is tasty is good for your health. It is really hard to resist unhealthy food because of their availability on the market. Media also advertise more on unhealthy junk foods rather than healthy ones. Unhealthy food may be a reason for us to be fat. If you want to keep healthy, you must first get rid of unwanted fats and be fit as possible.


Some athletes also have low nutritional levels because of certain factors. One is poor understanding of sports nutrition principles. They think that eating many will make the healthy.


Nutritional requirements also differ among people depending on their training program and personal characteristics like age, sex and body type. Their failure to recognize these may also cause malnourishment as they may take too much or less of their nutrients required.


Some athletes also diet too much compromising their nutritional needs. Their lack of knowledge on nutritional facts also contributes to it. Their lack of time and opportunity to eat and the tendency to skip meals is also one reason. Overeating is also a factor of malnourishment because you might eat and take in a lot of fats and unwanted chemicals that may be unhealthy.


The sports nutritional health can be broken down into the foundation of what food is basically made of namely proteins, carbohydrates and fats. We should get optimum amounts of these types for more energy and more muscle gains. You can only lose more than one pound of fat per week if you exercise properly and eat the right food instead of starving yourself. Starving will only bring you malnourishment.


If you are losing fat quickly by starving yourself, over dieting and doing too much exercise, you may be at a risk of slowing down your metabolism and your body might start using the glucose found in your muscles as a source for energy. That is why losing weight bit by bit for a long period of time instead of losing weight quickly is much more preferable.


There are toxins found in our fatty tissues and when we loose fat, these toxins are released back into our body. Losing too much fat in a short period of time means that you are releasing more amounts of toxins into the body causing us to be sick.


On your diet, try to avoid eating food with too much saturated fat because they are bad fats and will make you gain more weight. What you should do is to ingest unsaturated fats of the good fat because it will help you lose weight.


By eating good oils like deep-water fish oil, flax seed oil and linseed oils, you are actually aiding yourself as it rids your body of fatty deposits helping you lose more fat. This weight loss program actually takes a lot of time so only take measurements every two months to give you a better look on how your are progressing on keeping fit and sexy and how much fat you are actually losing.


I discourage you on taking those commercial diets because they will only set you up for failure and disappointment. These diets make you lose fat so quickly that when you try to start eating again more than you did while on diet, you will gain weight very fast. You should look for a way to lose weight in a slow and realistic rate.


Here are some tips: First is to stay away from white sugar and all other natural sweetener. You should also stay away from simple sugars and take in slowly digested complex carbohydrates. Eat food high in fiber in order to detoxify. And lastly, exercise. The right combination of exercise and nutrients will give you a high level of sports nutritional health.

Sports Nutrition, Success Fuel

August 11th, 2010

Nutrition and sports performance is a complex and essential relationship for serious sports men and women to understand and it can help them achieve success in their chosen sport. Sports nutrition also aids injury prevention and speeds up recovery times from an injury. The correct diet and fluid intake coupled with appropriate training is the difference between winning and losing. Fuelling the body with the right nutrition can be key to success.


Good sports nutrition promotes brain function and muscle activity. Physical training and performance requires the right diet (quantity and quality) that will provide the athlete with energy. Each sport has its own individual requirements as does each individual sports man and woman. These requirements dictate the nutritional demands of training and competition. Sports nutrition applies scientific methods to the applications of the sport to provide a diet that meets the needs of both athlete and discipline.


Sports performance is fundamentally affected by dehydration. The importance of water and fluid replacement in sports nutrition is paramount to supporting the activity of tissue cells in the body. These cells carry nutrients and oxygen around the body, eliminating toxins and removing excess body heat. During physical exercise, body heat increases and water is lost through evaporation or sweating. In hot environments, sports activity can attribute to sweat losses of 4-5 pints an hour. Water loss is partly offset by metabolic water produced from proteins, carbohydrates and fat metabolising in the body. However, sports nutrition dictates that hydrating the body properly requires fluid intake before, during and after activity.


A sports nutritionist will calculate fluid losses by measuring body weight before and after a session to determine how much fluid is required. Optimum levels should never be exceeded as overloading on fluids can lead to stomach discomfort and breathing difficulties during the activity. Modern sports nutrition recommends special carbohydrate-electrolyte drinks for intense activity that has a longer duration but water is typically recommended for low to moderate level activity.


A diet rich in carbohydrate and low in fat improves long-term and short-term sports performance. High-intensity exercise requires more carbohydrates to ensure the liver and muscle glycogen levels are high. High liver and muscle glycogen levels improve performance and glycogen present in the liver is a source of glucose for the brain (important for concentration, alertness and reaction time). A wide range of carbohydrates are required to ensure essential vitamins and minerals are present. Potatoes, bananas, pasta, bread, vegetables, cereals and porridge are a good source of carbs for sport.


Protein plays an important role in sports nutrition by building muscle and repairing it. Athletes should aim to eat a range of foods that will provide the necessary levels of protein. Foods such as lean meat, fish, eggs, beans and pulses, milk, yoghurt, cheese and cereals will provide protein needs. High protein sports nutrition does not necessarily lead to greater muscle mass as excess protein in the body is metabolised or excreted. The extra amount of food required for sport is usually enough to provide the correct intake of protein without resorting to increased portions or protein supplements. High-protein diets can be expensive and will decrease the bank balance before increasing muscle mass. A good sports nutritionist can ensure there are adequate nutrients and calories for an athlete to support the requirements of their sport.
