Important Facts to Learn from Studies about Growth Hormones


More than 65 years ago, scientists learned of the brain’s pea-sized pituitary gland, its secretion of growth hormones and the stimulants to which it responds. While previous studies showed that exercise can increase growth hormones (GH) secretion, environmental temperatures can affect the release of GH.

Passive heating is considered a potent stimulus for GH release. In contrast, exercise performed at 4°C, a cold temperature, could only result in suppression of growth hormone secretion.

Effect of Temperature on Growth Hormone Secretion

Passive heating by the way refers to heat created by a space heating system that is reliant on solar energy, and using materials like stones, concrete or water, which have large capacities to store and deliver heat.

Apparently, increase in temperature is an accompanying condition to growth hormone secretion. Exercise performed under high heat conditions stimulate sweat secretion that tends to increase the levels of GH secretion. On the other hand, increased heat conditions but with reduced sweat secretion can lead to GH deficiency.

The role played by the neurotransmitters involved in the secretion of growth hormones remains a mystery. Nonetheless, scientists found out from further investigations that a certain gut hormone called ‘ghrelin’ has stimulatory effect on the body’s level of food intakes, far absorption and deposition, as well as release of growth hormones.

About Ghrelin, the Gut-Secreted Growth Hormones

According to studies about ‘ghrelin,’ levels of this gut hormone tend to increase and decrease with the amount and type of food and beverage, including water, taken in by the body. Still, other previous studies focused on the effects of environmental temperature and its effect on the release of the gut hormone ghrelin.

Comparisons were made of ghrelin levels of concentrations at different temperatures during exercise and during rest period. Exercises performed at 36°C and at 25°C showed different levels of ghrelin concentrations, where the higher temperature reduced the gherelin levels. The reduced gherelin level resulting from exercise during the higher 36°C temperature also significantly reduced energy intakes derived from food.

However, the study made no mention about comparison of appetite levels for exercises performed during neutral, cold and warm environmental temperatures. The purpose of the studies was just to compare the appetite-regulating responses of exercise performed under different environmental temperatures.

Conclusion: Several Factors Influence Human Growth Hormone Secretions

In knowing that several factors influence the human body’s capability to secrete growth hormones, it’s easier to understand why physicians prescribe steroids but only under their medical supervision.

Some are inclined to take metandienone a.k.a. methandrostenolone as the best alternative to dbol because they are the most affordable brand of androgen/anabolic steroid medication. Yet the discussion above shows that human growth hormone (HGH) secretion does not respond to protein intakes alone.

Under normal conditions, HGH is released periodically, at some point during stages of sleep and certain times of the day as a result of stimulating physical activities like exercise. Besides, the best use of metandienone if for bodybuilding purposes is during the bulking stage and not as part of the maintenance stage.
