To examine the effect of how different dosages of egg protein powder
affected protein synthesis rates; researchers had young healthy men who
had previous resistance training experience perform intense resistance
exercise and consume a egg protein drink that contained either 5, 10,
20, or 40 grams of egg protein.
Interestingly, they found that increasing protein intake stimulated protein synthesis in a dose dependent manner up to 20 g of dietary protein, after which there was no further increase in protein synthesis (40 grams did not stimulate protein synthesis greater than 20 grams).
This data suggest that there is a maximal rate at which dietary Amino Acids can be incorporated into muscle tissue and that with increasingly higher concentrations of Amino Acids, there is no further stimulation of muscle protein synthesis. While current dietary guidelines in Canada and the United States suggest consuming0.8 grams of protein per kilogram of body mass daily, there is reasonable evidence that 1.1 grams is appropriate for serious endurance athletes and 1.3 grams for serious strength athletes.
Timing also matters:
You’ll build muscle more effectively if you take in protein within about an hour of finishing your workout. The optimal post-workout dose is about 20 grams, according to a McMaster study in the January issue of the American Journal of Clinical Nutrition. That’s equivalent to about 600 millilitres of skim milk, four medium eggs or 80 grams of cooked beef.
So how many times in a day could someone consume such a dose (20 grams) to stimulate muscle anabolism that would ultimately translate into muscle growth?
The researchers speculated that 5-6 times daily of small 20 grams of protein would be the optimal measure to increase anabolism and increase muscle mass. One thing that should be addressed is that they used egg protein which many bodybuilders do not use anymore; whether this applies to whey protein is not known.
In an interview about his study, Dr. Phillips has stated that, although egg protein was used, whey protein may be the most effective in stimulating muscle synthesis.
