How Exercising Increases Growth Hormones Production
The Exercise stimulated Growth Hormone Response to chaotic exercising is associated with the intensity, duration, frequency and mode of the exercise.
A number of studies have recommended an intensity ‘threshold’ prevails for Exercise induced Growth Hormonal Reaction. Vigorous exercising above lactate limit and for not less than 10 minutes seems to elicit the greatest stimulus to the secretion of H.G.H.
Exercise working out above the lactate limit may increase the pulsatile launch of H.G.H at rest, improving a 24-hour H.G.H secretion.” According to the study, Intense anaerobic work raises Exercise Triggered growth Hormone Reaction as well. So this would include weight lifting as well as body weight workouts if they were extreme enough.
Studies also show that a 30 second sprint raises H.G.H levels by up to 530% over the resting baseline. Repeated short intervals can further increase the release of H.G.H…but its a case of the law-of-diminishing-returns.
The second intense workout produces less of an H.G.H response compared to the first, the third less than the second, etc. To release maximum H.G.H through exercise, you need to do intense exercise and aim to reach your Lactate threshold.
At rest and under steady-state exercise conditions, there is a balance between blood lactate release and blood lactate removal (Brooks 2000). The lactate threshold refers to the intensity of exercise at which there is a spontaneous increase in blood lactate levels (Roberts & Robergs 1997).
Therefore when muscle tissue contract intensely for a long period, the blood circulation system starts to lose ground in circulation of fresh air (necessary for energy release). In these circumstances the breakdown of sugar is changed to lactic acid.
As the lactate is created in the muscle tissue, it oozes out into the blood stream and is distributed around our bodies. If this situation continues, our body performance reduces and the muscle tissue wears out very quickly.
This point is often calculated as the lactate limit. The point when muscle is fatigued to the point of almost failing to move voluntarily. The training system will soak the muscles in lactic acid, which will train the body’s loading procedure to deal with lactic acid more efficiently. Thus raising the anaerobic (lactate) threshold.
The lactic acid is not responsible for the burn in the muscles as you intensely work out, but the hydrogen ions released as the lactic acid leaks out. An increase in blood lactic acid levels is a major trigger of growth hormone (H.G.H) release.
Increasing H.G.H, is beneficial for gaining muscle / lean tissue and reducing fat and growth of bones.
