Glycemic index is the measure of how quickly blood glucose rise after eating a particular kind of food. This is used by estimating the how much each gram of carbohydrate consumed raises a person’s glucose level. During intense exercise, the body uses glucose as energy source before it starts relying of fats. “Prolonged exercise can only be continued when there is an adequate amount of carbohydrate available to fuel muscle and the brain”(William,2004). This shows that the amount of carbohydrate/glucose that is found within the body’s tissue has a significant amount of influence to play on how effective the early hours of an exercise would be. Glycemic index helps one to know how effective the carbohydrate/glucose within the body is functioning during exercise.
There are foods that have been known to have a higher glycemic index and others with a low glycemic index. However, how large of small the glycemic index value of a particular food maybe does not just tell a person how much effective the blood glucose level is responding to effectiveness energy burned. This glycemic index can also help in a person’s plan or eating habit. According to mayo clinic dietician association does statistics on Glycemic index from the Sydney University Glycemic index research center, glycemic index is ranked from 0-100 constitute only foods and beverages that contain carbohydrate. “Food with high glycemic index scored 70 and above on the glycemic index scale. These foods include; plain white bread, brown rise, white rice, watermelon, boiled red skin potato and white skinless baked potato. Food with median glycemic index range from 56 to 69. These foods include; sweet corn, bananas, pineapple, raising and a few kinds of ice cream. Food with low glyce...

...ther; HGI of LGI has a great impact on the performance of a person when ingested before exercise. One thing, I believe will also impact on the effectiveness of either group is how long they had been taken before the exercise. This is because the time interval will help determine if much of the food is already in the blood to start generating glucose once the exercise had begun. A comparison of earlier researches about the difference in exercise for HGI snd LGo were compared and contrasted by to researchers. They rated different studies that used similar approach in their research experiment. Their analysis showed that; “the when participant consumed HGI prior to exercise, their exercise times were lower than when they consume LGI”( Williams,2006). . However, they did not find any significant difference between their run times to fatigue for the HGI and that of LGI.
Glucose consumption in the tissues and glucose production are balanced when the body is at rest. At the start of exercising the energy the body gets quickly is from the anaerobic metabolism using mostly muscle glycogen...
Today many people are substituting normal meals with energy bars in hopes of losing weight. These energy bars seem to be an easy way to diet without having to hunt down the proper nutritional meals; the meal is already prepared for you in the bar. There are a few questions being raised about this method of dieting however. The issue addressed in this paper is the use of energy bars that either have low carbohydrate levels or that use lower glycemic index carbohydrates. The idea behind using an energy bar of this type for dieting is to lower the levels of insulin in the blood, reduce cholesterol levels, and prevent the drop in blood glucose that is thought to be associated with feeling hungry.

Frank Katch, William McArdle, Victor Katch and James Freeman did research in 1998 that suggested that the first nutritionists came out of the early Olympics between the years of 776 BC and 393 AD. During this period paidotribes, which were private trainers or coaches, advised their athletes about the importance of food and exercise. One of these early coaches was Melesias. Melesias was one of the most educated nutritionists in his era. He coached 30 wrestling champions (Wolinsky p.8).
Insulin is a protein hormone that is secreted in the pancreas and is responsible for regulation of blood glucose levels in the liver, muscles, and fat cells where it is used for cellular metabolism. Once stimulated, the glucose is then converted into glycogen in the blood. In this experiment, subjects were tested on the effects Coca Cola, water, and doughnuts had on the blood glucose levels. Prior to the experiment, subjects were instructed to fast in order to maintain a baseline blood glucose level. One specified subjects’ blood glucose levels were monitored after drinking Coca Cola and the other subjects’ blood glucose levels were monitored after drinking water. Meanwhile the remaining subjects’ blood glucose levels were monitored after eating doughnuts. The sugar that is found in

When a person exercises the body uses either sugar or fatty acids as fuel to create energy. During the beginning of an exercise most of the sugar that is used as fuel comes from the bloodstream or the muscles. After about 15 minutes the fuel starts to come from the liver. When one exercises after 30 minutes the body receives energy from free fatty acids and glycogen gets stored resulting in a decrease in blood sugar levels. Glycogen is the sugar stored in the liver and muscles.

Post exercise, it is recommended to consume a moderate to high glycemic index food that is readily available to replenish glycogen stores (Stoppani et al., 2008). This may also provide an insulin response that could attenuate muscle protein synthesis (Stoppani et al., 2008). Moderate GI foods include rice, sweet potatoes, citrus juices, pasta, corn, pita bread, mango, kiwi, and bananas. High GI food include raisins, honey, carrots, watermelon, sports drinks, bagels, pancakes and waffles, baked and mashed potatoes, and pretzels (Bonci, 2009).
The buzz word for the last few years has been low GI. The glycemic index (GI) is a ranking of carbohydrates on a scale from 0 to 100 according to the extent to which they raise blood sugar levels after eating. Foods with a high GI are those which are rapidly digested and absorbed, and they result in big spikes in blood sugar levels. Low-GI foods, because they are digested and absorbed by the body more slowly, only produce gradual rises in blood sugar and insulin levels, and have proven benefits for health. Low GI diets have been shown to improve both glucose and lipid (fat) levels in people with diabetes (type 1 and type 2). They have benefits for weight control because they help control appetite and delay hunger. Low GI diets also reduce insulin
There is a relationship between food and exercise and people do not understand that. Everyone needs food in order for their body to work properly and do their daily activities, especially exercising. Without good nutrition, one will not be able to exercise effectively. To exercise effectively, one need the right caloric intake, energy, and nutrients in one’s body. The human body needs have carbohydrates, protein, fats, vitamins, minerals, and water to fuel it up, just like the car needs gas to run. Everyone should fuel their body with right foods so that they can maintain their energy levels. Bananas and lean white meats are examples of excellent sources of natural energy that can help the function properly and achieve fitness goals. Bananas are an excellent food to eat because they contain high potassium, makes the mind alert making the brain smarter, builds strong bones, and keeps the digestive system regulated. Lean white meat such as chicken and fish are good to eat because they make the tissues in the body healthy. Good nutrition is more important because if the body absorbs the nutrients it needs, one will be able to exercise very
