protein timing for net gain.

Although the importance of postexercise nutrient ingestion timing has been investigated for glycogen metabolism, little is known about similar effects for protein dynamics. Each subject (n = 10) was studied twice, with the same oral supplement (10 g protein, 8 g carbohydrate, 3 g fat) being administered either immediately (EARLY) or 3 h (LATE) after 60 min of moderate-intensity exercise. Leg blood flow and circulating concentrations of glucose, amino acids, and insulin were similar for EARLY and LATE. Leg glucose uptake and whole body glucose utilization (D-[6,6-2H2]glucose) were stimulated threefold and 44%, respectively, for EARLY vs. LATE. Although essential and nonessential amino acids were taken up by the leg in EARLY, they were released in LATE. Although proteolysis was unaffected, leg (L-[ring-2H5]phenylalanine) and whole body (L-[1-13C]leucine) protein synthesis were elevated threefold and 12%, respectively, for EARLY vs. LATE, resulting in a net gain of leg and whole body protein. Therefore, similar to carbohydrate homeostasis, EARLY postexercise ingestion of a nutrient supplement enhances accretion of whole body and leg protein, suggesting a common mechanism of exercise-induced insulin action.

Take your protein as soon as possible .....

GOOD POST BRO!!! YOU HAVE MAIL!!!!!!!!

Awsome article, I have ben somewhat neglecting my diet lately.
Best regards from Shine.

i find that stoping mid workout, shooting slin, slaming a protien shake, and drinking 10mg sugar/iu of slin and running back downstairs to continue my workout pumps me like crazy...if possoble, i'd even say drink the shake during the last half of the workout

i agree chili. i always start drinking my shake at the halfway point in my wotkout. just start sippin it and make sure it is gone by the end. just started labrada prov 60- good stuff.

Hey thanks D-F. Was just talking about this today! I was wondering if I was under the impression that I should put the proteins in and then start working out. I misunderstood. He actually said he goes home for 2-3 hours eats and then comes back to the gym and works out. This kinda clears things up for me, I'll do my cardio & workout on an empty stomach, immediately after workout I'll drink a protein shake. Thanks man

Good Post! Always good to see something you preach in a study.

Good post, very informative. Sometimes I tend to stray from my diet.
