Protein intake key factor in growth hormone's anabolic effect
Study
The liver manufactures most of the IGF-1 molecules in the blood. The liver produces more IGF-1 as the concentration of growth hormone in the blood is higher. The muscle building effects of growth hormone are mainly the work of IGF-1.
Here's how the body regulates growth hormone and IGF-1 release.
Results
Best respondes were Pt 1, Pt 2 and Pt 5.
Below you can see how much nitrogen (say dietary protein) the subjects consumed daily and how much nitrogen the subjects could retain (say: whether they were in an anabolic or catabolic state). All patients were malnourished, which is typical of their illness.
1 gram of nitrogen is approximately equal to 6.25 grams of protein.
The figure suggests that protein intake is an important factor in the anabolic activity of growth hormone. The subjects who did not respond to growth hormone, Pt 3 and Pt 4, had the lowest protein intake. The subjects who responded best to growth hormone treatment, Pt 1, Pt 2 and Pt 5, had the highest protein intake.
