Charles Poliquin's Biosignature Modulation - What Your Body Fat Tells You About Your Hormone Profile

Growth Hormone Sites

Knee and Medial Calf

Growth hormone is a hormone that is synthesized and secreted by the somatotroph cells of the anterior pituitary gland. It plays a major role in controlling physiologic processes such as growth and metabolism. GH stimulates the liver and other tissues to secrete IGF-I (Insulin-like growth factor 1). By stimulating the proliferation of cartilage cells, IGF-I plays an important role in both bone and muscle growth.

The skin fold values for the knee and calf sites give you an indication of growth hormone levels. While the knee is indicative of short-term growth hormone levels, the calf gives information about longer-term GH levels. These two sites reveal a great deal of information about sleep quality, duration, and late night partying, because growth hormone production is dependent upon sleep.

Estrogen Sites

Quadriceps and hamstrings

Estrogens, produced from androgens through enzymatic actions, are the primary female sex hormones. The three major naturally occurring estrogens in women are estradiol, estriol, and estrone.

The values for the quadriceps and hamstrings sites are indicative of your ability to manage estrogen levels. As they are related to overall estrogen level, as well as ratio, females get more latitude in this area then males. For men, the quadriceps and hamstrings should approach the same value as the triceps, which indicates lower estrogen values.
