g'day my friends
today i want to talk about stretchmarks
stretch marks are basically a response to glucocorticoids (produced by the upper cortex of the adrenal glands and chemically classified as a steroid) when very high levels of this hormone exist in the body, the skin loses its ability to produce the necessary collagen and elastic fibres that allow the skin to stretch without damage
during rapid stretching or growth the elasticity in the skin breaks that's why adolescents, pregnant women and weightlifters (mostly men, and predominantly in the upper arm/shoulder area) are prone to stretch marks
yours in training,
