תרגילים מורכבים, שמערבים יותר ממפרק אחד, גורמים לשחרור רק יותר של GH.
על יתרונותיו של GH מויקיפדיה:
Effects of growth hormone on the tissues of the body can generally be described as anabolic (building up). Like most other protein hormones GH acts by interacting with a specific receptor on the surface of cells.
Stimulating the increase in height in childhood is the most widely known effect of GH, and appears to be stimulated by at least two mechanisms.
GH directly stimulates division and multiplication of chondrocytes of cartilage. These are the primary cells in the growing ends (epiphyses) of children's long bones (arms, legs, digits).[citation needed]
GH also stimulates production of insulin-like growth factor 1 (IGF-1, formerly known as somatomedin C), a hormone homologous to proinsulin.[9] The liver is a major target organ of GH for this process, and is the principal site of IGF-1 production. IGF-1 has growth-stimulating effects on a wide variety of tissues. Additional IGF-1 is generated within target tissues, making it apparently both an endocrine and an autocrine/paracrine hormone. IGF-1 also has stimulatory effects on osteoblast and chondrocyte activity to promote bone growth.
In addition to increasing height in children and adolescents, growth hormone has many other effects on the body:
Increases calcium retention, and strengthens and increases the mineralization of bone
Increases muscle mass through sarcomere hyperplasia
Promotes lipolysis
Increases protein synthesis
Stimulating the growth of all internal organs excluding the brain
Plays a role in fuel homeostasis
Reduces liver uptake of glucose
Promotes gluconeogenesis in the liver[10]
It contributes to the maintenance and function of pancreatic islets
It stimulates the immune system
