Increased p70(s6k) phosphorylation during intake of a protein-carbohydrate drink following resistance exercise in the fasted state.

The present study aimed at comparing the responses of myogenic regulatory factors and signaling pathways involved in muscle protein synthesis after a resistance training session performed in either the fasted or fed state. According to a randomized crossover study design, six young male subjects participated in two experimental sessions separated by 3 weeks. In each session, they performed a standardized resistance training. After the sessions, they received during a 4-h recovery period 6 ml/kg b.w. h of a solution containing carbohydrates (50 g/l), protein hydrolysate (33 g/l), and leucine (16.6 g/l). On one occasion, the resistance exercise session was performed after the intake of a carbohydrate-rich breakfast (B), whereas in the other session they remained fasted (F). Needle biopsies from m. vastus lateralis were obtained before (Rest), and 1 h (+1h) and 4 h (+4h) after exercise. Myogenin, MRF4, and MyoD1 mRNA contents were determined by RT-PCR. Phosphorylation of PKB (protein kinase B), GSK3, p70(s6k) (p70 ribosomal S6 kinase), eIF2B, eEF2 (eukaryotic elongation factor 2), ERK1/2, and p38 was measured via western blotting. Compared with F, the pre-exercise phosphorylation states of PKB and p70(s6k) were higher in B, whereas those of eIF2B and eEF2 were lower. During recovery, the phosphorylation state of p70(s6k) was lower in B than in F (p = 0.02). There were no differences in basal mRNA contents between B and F. However, compared with F at +1h, MyoD1 and MRF4 mRNA contents were lower in B (p < 0.05). Our results indicate that prior fasting may stimulate the intramyocellular anabolic response to ingestion of a carbohydrate/protein/leucine mixture following a heavy resistance training session.


I'm not sure if this matters much in the long run but it's pretty cool and supporting the idea that training in a fasted state isn't a catabolic disaster.

Good stuff. I am always for more studies.

That study reminds me of the leucine thread we had going. I might have to resurrect that soon. That was an interesting one.

Bumping this!

30th september I weighed 67,3 kg and had 6,8% bodyfat. Today (3/12) my weight is 68,9 kg and my bf% is 4,7. That means I've lost 1,2 kg fat and gained 2,8 kg fat free mass. IF rules, get into it.

I wonder how well this works when you don't exercise...

Nice, Johan!

I am not sure where my body fat is, but I have dropped 7lbs and gained a bunch of strength since two months ago. I think I might nail a 405 deadlift in a few weeks.

BTW everyone, the leangains.com blog was updated recently with two parts of an interview with a champion female figure competitor who uses IF.

405 deadlift would be awesome!

Also check leangains.com for Martins comments. Really nothing new but still cool!

Then when I get home, I eat a soup made with
2 cups dried beans, cooked
1lb leafy greens
1lb solid vegetables
1 6oz can tomato paste
1/4 cup nutritional yeast
1/4 cup nuts/seeds
I blend half of it to make a creamy soup, then eat half of it, usually with a piece of fruit and some carrots.



What kinds of combos of nuts and seeds are you using Cubby?

Mostly flax, sunflower, pumpkin and black sesame for seeds. Walnuts, almonds and Brazils for nuts.

Does it make a difference on how you combine them? Do they taste better or worse with certain configurations? Are they just about the same due to mild flavors?

Pumpkin, black (or white) sesame and Brazil are the only ones with a strong flavor. Pumpkin seeds are great for Italian food, sesame is great for Chinese/Japanese and Middle Eastern, and Brazil nuts are good anywhere you would put peanuts.

http://www.leangains.com/ has a new post. It is about fasted state workouts and how a recent study showed an increase in certain factors post workout that assist in muscle building. There is a link to the study right at the top of the post. Interesting stuff, but obviously not enough evidence to go and make all your workouts fasted from now on. It really makes me want to start taking some BCAAs pre-workout as my first "food" for the day.

I posted the abstract of that study on the top of this page (page 7) almost a month ago :wink:

I didn't realize it was the same study. I forget a lot in one month. Oh well, now we have a perspective on the study from two Swedes. :D

Leangains.com was a good post. I was suprised it took such a long time for Martin to comment the study but hopefully he was busy writing on his book.
