No, they are counterproductive in every way for endurance athletes. Not only will you compromise performance but you will also not recover properly leading to less productive workouts that further reduce your performance potential. Carbohydrates (fruit, breads, pasta, rice, potatoes, etc) are the body’s primary and preferred energy source. Once eaten, they rapidly break down to blood sugar (glucose). The brain, nervous system and muscles are fueled mostly by glucose. Therefore, a continuous supply of carbohydrate is necessary to prevent body stores from being depleted. Not getting the right amount of carbohydrate leads to low energy levels, fatigue and significantly impaired performance. Proper management of the amounts, types and timing of this nutrient is required to fill and refill the body's main “fuel tank”.
Key carbohydrate guidelines are listed here:
• Carbohydrates should make up approximately 60 percent (55-70 is the range based on length of activity -higher for longer) of your total diet.
• Starches and grains should be eaten at each major meal throughout the day to provide a lasting energy source. Major meals should be eaten every three to four hours.
• Carbohydrates such as fruit, energy bars/shakes, and sports drinks are ideal for rapid fueling before activity to “top off” the fuel tank and immediately after exercise to optimize recovery. The pre- and post-exercise timing is very important!
• Depending on the sport, growing athletes should consume 3 to 4.5 grams of carbohydrates per pound of body weight every day.
