Information about Sports Nutrition
Sports nutrition is applied in most sports training, however it is most dominant in strength sports (for example weight lifting and bodybuilding) and endurance sports (for example cycling, running, triathlon).
For the purpose of protein synthesis, amino acids are ingested as well. Studies also show that there is a greater rate of glycogen synthesis when amino acids are included with the ingested carbohydrate.
Nutrition for anaerobic exercise
After weight training, the body is depleted of glycogen stores. This creates a rise in Glycogen synthetase, which allows for a greater amount of glycogen synthesis for a period after training. To compensate for this glycogen depletion, athletes will often take in a large amount of carbohydrates in the period immediately following exercise. Typically, high glycemic index carbohydrates are preferred for their ability to raise insulin levels, thus increasing rate of nutrient storage. Recently, High Molecular Weight carbohydrates have come to prominence for their low osmolality, and potential for quicker, and greater glycogen restoration.For the purpose of protein synthesis, amino acids are ingested as well. Studies also show that there is a greater rate of glycogen synthesis when amino acids are included with the ingested carbohydrate.
Nutrition for aerobic exercise
After the aerobic exercise it is necessary to fill the glycogen stores in the muscles. A liquid source of fast carbohydrates and protein in ratio 4:1 are generally recommended for optimal recovery.Goals of sport nutrition
Some of the main goals of sport nutrition are to:- prepare athlete for performance or training (before)
- maintain the level of performance or training (during)
- help recovery from performance or training (after)
