What is carbohydrate loading?
Nicholas M.
Many long-distance runners carb-load before an endurance event like the marathon (running 26.2 miles). Carbohydrate loading involves eating carbohydrate-rich meals several days to one week before the event. In fact, many groups sponsor dinners the night before a race and serve high-carbohydrate foods like pasta. However, studies are mixed about the usefulness of this practice. Regardless of its efficacy, what is the reasoning behind carbohydrate loading? Decreasing the amount of fat and protein in the diet helps with weight loss, which can improve endurance and speed. Excess carbohydrates are stored as triacylglycerols, which can be oxidized during anaerobic metabolism. Excess glucose is stored as muscle or liver glycogen, which can be broken down to supply energy during the event. Glucose is stored as glycogen, reducing the amount of lactate generated in muscle during the event. Excess glucose enables the body to produce more ATP, which is stored in the body and can be used during the event.
