For short, high-intensity exercise, the main source of energy is glycogen (glucose) stores in muscle and the liver. For longer duration exercise, carbohydrate utilisation will vary depending on intensity, type of training and overall diet.

What is the primary source of energy during exercise?
Carbohydrate is the primary fuel for most types of exercise and the most important nutrient for athletic performance. Our body runs most efficiency with a balance of protein, fat and carbohydrates, but adequate carbohydrate is a key source of energy for athletes.
What carbohydrate source does exercising muscle prefers to use?
Assuming that both muscle glycogen and blood glucose concentrations are adequate, exercising muscle cells prefer to use blood glucose rather than muscle glycogen.
Why are carbohydrates important for exercise?
Carbohydrates fuel the brain and muscles.
Think of it as fuel for your car: our bodies store carbs in our muscles as glycogen, which is then converted to glucose when you need it. Carbs help delay fatigue, sustaining you through prolonged workouts or competitive sports.
How many carbohydrates should be consumed during exercise quizlet?
The recommended carbohydrate intake during exercise is 30-60 g of carbohydrate per hour.
Why is carbohydrate called carbohydrate?
The American Diabetes Association notes that carbohydrates are the body’s main source of energy. They are called carbohydrates because, at the chemical level, they contain carbon, hydrogen and oxygen. There are three macronutrients: carbohydrates, protein and fats, Smathers said.
Why carbohydrates are the main source of energy?
Carbohydrates are the nutrients most frequently used as an energy source (containing 4kcal per gram), as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body. The energy that powers the brain and body is generated when carbohydrates are broken down.
What are sources of carbohydrates?
Carbohydrates are found in a wide array of both healthy and unhealthy foods—bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and cherry pie. They also come in a variety of forms. The most common and abundant forms are sugars, fibers, and starches.
