Wolf Abstract: leucine, are known to stimulate muscle protein synthesis and anabolism. However, performance data

additional leucine to enhance muscle anabolism response to resistance exercise and protein reception is unclear. Thus, we investigated the response of muscle protein balance in receiving additional leucine with protein in association

tion resistance exercise. Two groups of untrained subjects performed intense leg workout battle followed

ING taking 1 of 2 drinks: flavored water (PL), or 16. 6 grams of whey protein + 3. 4 g of leucine (W + L). Arteriovenous amino acid

balance between his legs was measured to assess the anabolic response of muscle in each group. Arterial amino acid concentrations >> << increased due to the use of W + L. Amino acid concentrations peak between 60 and

120 minutes after eating, and then decreased to baseline values. Valine concentration decreased to a level much lower than

line. Net balance of leucine, threonine, phenylalanine and did not change after taking the LP, but increased

left and rises above the base for 90 120 minutes after ingestion W + L. Leucine (138 to 37 and 23 23 mg)

phenylalanine (58 28 and 38 14 mg) and threonine (138 by 37 and 23 to 23 mg), absorption was higher for W + L, than

for PL at 5. 5 hours after meal drink. Our results indicate that whey protein plus leucine in healthy young
