710 Words3 Pages
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... ... middle of paper ... ...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.
