Carb Counting: More Than Just The Amount NUTRITION | JENNI KLUF A MS, CISSN Pre-Exercise It is estimated that it takes 4-6 hours for 200 grams of carbohydrate to be ingested and readi-ly available for liver and muscle use in the form of glycogen. Therefore, athletes should begin to focus on meals 4-6 hours prior to their workout and should aim for 3-4 g/kg of carbohydrate. Approximately 30 minutes prior to exercise, the athlete should again ingest carbohydrates with a goal of about 1 g/kg. During Exercise Carbohydrates are quickly depleted during endurance activities and need to be replenished constantly for any activity lasting longer than 60 minutes. The goal during exercise is to be proactive with carbohydrates. Have them ready to be restored before they are depleted. To do so, an athlete should consume 1 g/kg of carbo-hydrate every hour of exercise. The preferred method would be 0.5 g/kg of carbohydrate ev-ery 30 minutes if possible. Post Exercise Recovery is just as important as the pre-exercise and during exercise regimens.
