Why I am interested in natural release of human growth hormone

By Mark Leigh

I think that inducing the natural release of growth hormone is a very effective way to improve mental and physical health.

In some ways I feel that I am one of the pioneers in determining how to promote health through the natural release of growth hormone.  Although I am not a scientist or athletic trainer and I don’t have any other credentials, I have experimented with exercise, diet, and other protocols for a year.  I hope the information in this blog becomes a way to help others receive the benefits of the natural release of growth hormone that I have received; I also hope that readers of this blog will share their experiences.  As pioneers, we can help each other.

In February 2007, I first became aware of exercise-induced release of human growth hormone while researching ways to improve my cholesterol readings.  Through changing diet and exercise, within a couple of months my cholesterol readings became healthy, I lost weight, and the pain in my right hip (of 3 year’s duration) disappeared.

 I am 56 years old.  My priorities are to feel good, to look and feel strong, and to age as gracefully as possible.  I would like to be able to run fast and be athletic, but I don’t plan on being involved in competitive athletics. I don’t want to look like a body builder with bulging muscles.

    Hi Mark: I am a 52 yr old male trying Sprint 8. I am only at the end of 2nd week. (Will be doing 4th Sprint workout tonight). No changes yet obviously, will keep you posted. Did you completely switch to Tabata from Sprint 8 and if so may I ask why?

    Thanks and keep going!

    Hey Dave: I did Phil Campbell’s Sprint 8 workout for a year and I was happy with it. My hunch is that now that my sprinting muscles are in pretty good shape, the Tabata protocol will cause an even bigger surge of GH.
    Some studies have indicated that lactic acid (the anaerobic by-product of Type IIa fast twitch muscles) causes the GH surge. When you sprint you can feel a burning sensation in muscles and you can notice after about 50 yards that your sprinting speed will start decreasing as the lactic acid increases. Since the rest intervals of the Tabata protocol don’t allow much of the lactic acid to dissipate, I think the Tabata protocol might produce a bigger surge of GH and also create the acid environment in the muscles to rebuild stonger muscles.
    Sprinting is an intense exercise which has a risk of injury so I feel a need here to caution you and others to be careful whether doing the Sprint 8 or the Tabata protocol.
