Carbohydrate feeding during moderate intensity exercise postpones the development of fatigue by approximately 15 to 30 minutes, yet it does not prevent fatigue. This observation agrees with data suggesting that carbohydrate supplementation reduces muscle glycogen depletion.
Carbohydrates are important substrates for contracting muscle during prolonged, strenuous exercise, and fatigue is often associated with muscle glycogen depletion and/or hypoglycaemia.
How many carbs you need depends on your total calorie goal as well as your sport. For most athletes, 5 to 7 grams of carbohydrate per kilogram of body weight daily is right for general training. (Note that 1 kilogram equals 2.2 pounds.) Endurance athletes may need up to 12 grams per kilogram.
Having full glycogen stores and eating carbohydrates on runs over 90 minutes helps to delay fatigue and “hitting the wall” by sparing the glycogen stores from getting depleted. Once glycogen stores are depleted, fat becomes the primary source of fuel for exercise.
Complex carbohydrates are made up of lots of sugars combined together. Sources of complex carbohydrates that will give you long-lasting energy include whole grains, fruits and vegetables. Popcorn, brown rice, wild rice, quinoa, barley, oatmeal, bulgur and buckwheat are examples of whole grains.Dec 17, 2018

Carbohydrates provide energy for the body including our muscles, brain, nerves and other body tissues. Anytime we are performing an activity in which we need a lot of energy and fast, such as resistance training and carrying bags of mulch, carbohydrates are the predominant energy source during those activities.Sep 4, 2018
The strength/power athlete should eat approximately 2-3 grams per pound of body weight, with 55%–60% of their total daily energy intake from carbohydrates.
A diet rich in carbohydrates increases both endurance and intermittent high-intensity performance because of the extra store of carbohydrates in the muscles and liver, called glycogen.
During physical exercise stored carbohydrate or glycogen is converted into energy to fuel the muscles, but this supply is not endless. The amount of carbohydrate that can be stored in the body as glycogen depends on diet and the athlete's conditioning level.
Carbohydrate loading enables muscle glycogen levels to be increased to around 150-200 mmol/kg wet weight. It is estimated that this additional amount of muscle glycogen can improve endurance performance by 2-3%.Apr 4, 2019
