Nutrition Research Task – Year 10 Pass Carbohydrate loading is a strategy involving changes to training and nutrition that can maximise muscle glycogen stores prior to endurance competition. The technique was originally developed in the late 1960’s and typically involved a 3-4 day ’depletion phase’ involving 3-4 days of hard training plus a low carbohydrate diet. This depletion phase was thought to be necessary to stimulate the enzyme glycogen synthase. This was then followed immediately by

Carbohydrate Loading There are many threats to an athlete during physical endurance competition whether it is a marathon or the decathlon. The most common forms of these threats include hypoglycaemia‚ fatigue‚ and loss of morale (which is usually caused by hypoglycaemia and fatigue). There is one connection that can be made between these threats and that is that all are caused one way or another through the lack of carbohydrates (Peterson). The most common way to combat these threats

Carbohydrate Metabolism Carbohydrate metabolism starts with digestion in the small intestines. This is the site where monosaccharides are absorbed into the blood stream. This type of metabolism is basically considered to be glucose metabolism because carbohydrates are eventually broken down into glucose so that it can diffuse into the blood stream. There are three hormones in the body that control the concentration on glucose in the body: Insulin‚ glucagon‚ and epinephrine. If sugars are too
