Document Summary
Glycogen loading: depleting glycogen stores by exercising intensely and then replenishing glycogen by consuming a high-cho diet for a few days before competition. * high cho meal eaten 24 hours before exercising will fill glycogen stores. Taken with the intention to increase physical performance. Many b vitamins are promoted as such: thiamin. Act as carriers primarily in energy metabolism (important in amino acid metabolism) Cashed in for 2 atp in electron transport chain. Serves as electron carrier in electron transport chain. Important in the metabolism of fatty acids and amino acids. Acetyl-coa is produced during the breakdown of: Convert amino acids to glucose for energy. * the more protein you eat, the higher the b6 requirement. Important in the production of red blood cells. Folate deficient = cells are unable to divide (megaloblastic) Supplements have been shown to prevent oxidative damage but no performance enhance. Shown to enhance performance during moderate intensity and short-term intensity exercise.
