AMINO ACID SUPPLEMENTS , AND RECOVERY FROM EXERCISE Sports

Amino acids are always a minor source of fuel, usually accounting for less than 5% of total energy expenditure. If enough carbohydrate is ingested, i.e., ~1.2 g·kg-1·h-1 (0.55 g·lb-1·h-1) in 15-30 min intervals during the first 2-5 h of recovery, protein supplementation does not further increase muscle glycogen replenishment. However, if no food or too little carbohydrate is consumed, ingestion of protein or specific amino acids during recovery from prolonged exercise may accelerate glycogen resynthesis.
