> Long-term exercise is known to reduce serum levels of growth stimulating hormones. In contrast, the endocrine effects of acute endurance exercise include increased levels of mitogenic factors such as GH and IGF-1. Two points: 1. how to best understand "long-term exercise" vs "acute endurance exercise" in lay terms here roughly? 2. how mitogenic is growth hormone vs IGF-1? Raised GH seems to raise IGF-1 "usually", but for example during fasts for more than a day or couple of days, GH weirdly seems to go up very drastically while of course IGF-1, insulin, mTOR, leptin all trend ever-lower Always wondered whether the bodybuilders tried to raise GH for its own sake primarily or just in order to initiate the cascade of other "growth & proliferation" pathways..
