Carbohydrates for Pre- and Post-Workout Nutrition

Appropriate ingestion of carbohydrates provides various benefits anytime in pre-, intra- and post-workout.

Carbohydrates are one of the primary energy sources in the body. Depletion of this energy source causes a significant reduction of performance such as fatigue of the body and decreased concentration. For athletes, managing carbohydrate intake is very important.

Carbohydrates are mainly used as energy in a workout. The higher the exercise intensity, the ratio of carbohydrates utilized by the body is increased. Thus, appropriate ingestion of carbohydrates provides various benefits anytime in pre-, intra- and post-workout.

In a pre-workout setting, carbohydrate loading is well-known as a common strategy for endurance athletes such as marathon runners, bicycle racers and swimmers. These athletes ingest carbohydrates before workouts to maximize the storage of glycogen in the muscle and liver. Reduction of internal glycogen levels causes the deterioration of performance such as decreased exercise intensity and work output, thereby the ingestion of carbohydrate is very important to maintain the glycogen levels.

The consumption of carbohydrates port-workout contributes to quick recovery. After long-term, high-intensity exercise, the intra glycogen is depleted. By ingesting carbohydrates, you can quickly replenish muscle glycogen (Eur J Sport Sci. 2005;5:3-14; Sports Med. 2003;33:117-144).
