Anaerobic Exercise HGH Link
I love this stuff. A recent study published in the British Journal of Sports Medicine may help explain what I have been saying for quite some time here: that exercise stimulates the natural production of growth hormone (the very same HGH we just wrote about yesterday). But it’s the type of exercise that makes all the difference. And this further confirms something else we’ve been saying: that it’s short intense bursts that work the best.
While we have known this for years (that exercise and sleep are the best ways to produce natural HGH), there hadn’t been a good explanation of what kind of exercise was best or why certain forms of exercise had that HGH effect – and what exactly caused it. Until this paper. In this elegantly designed study, researchers used people with McArdle’s disease – people who don’t produce lactic acid – to show that when hard work is performed without lactate production, there is no EIGR (exercise-induced growth hormone repsonse). Very cool. OK, well, not for them…
As you also know by now, I was a chronic aerobiciser for 20 years, but have since reformed my ways. I was your typical skinny marathoner/triathlete with less muscle mass than I wanted – but I was always exercising like a fiend. Turns out the type of exercise I was doing was so much (that’s the chronic part) and so wrong for achieving health that I was “catabolic” much of the time (constantly breaking the muscles down instead of building them up). This of course also led to my being sick and injured a lot as well.
I now espouse weight-training and intense anaerobic bursts as a major part of my “Primal Blueprint“. These are exercise forms that we can use to naturally get stronger, leaner, fitter, healthier and even smarter. Sure some low level cardio is good for the heart once in a while, but the real results come from the anaerobic work. I am so pleased to see that this study shows that it’s the lactate (lactic acid) produced by intense anaerobic work that actually stimulates the growth hormone. The take-home message once again – if you want to get the most advantage from time spent exercising, pick those exercises that stimulate release of HGH naturally. It’ll take less time and you’ll show the results even sooner. Now, once I recover from the knee surgery I had last week, I’m heading to the beach for more sprints…

there are some related pieces of research – on GH and how to promote its secretion – that you might be interested in here:

So what are the best ways to maximize lactate production? Hard sprinting? Weights?
Does food intake of lactate (from sauerkraut, yogurt) contribute to the effect?
Sasquatch,
Yes, hard sprinting and weights are best. No evidence that lactate from foods has any benefit whatsoever.
Sasquatch, here are some specific examples of excercise that you can do to get a lactate response (you may have seen them before):
Complete as many rounds in 20minutes of 5 kipping pull-ups, 10 push-ups, 15 squats (with no added weight). In fact, you can pick any 3 excercises and put them into this frame.
Another good one is tabata intervals. Squat (again with no added weight) as many times as you can for 20 seconds. Then rest for 10 seconds. Repeat this cycle 8 times (a total of 4 minutes). This also works with kipping pull-ups, push-ups, sit-ups, good mornings, spring running, and pretty much any other excercise that you don’t need superb form to do safely – complicated moves, such as gymnastics back saltoes can get dangerous performed in this fashion.
The good thing about both these routines is if you repeat them from time to time (ie once per month) you can measure your progress easily. Notice that both require a stop watch and both do not allow you to recover before performing the cycle again. It’s as if you are sprinting through the rounds, but not actually running. If you would like more suggestions let me know.
I meant to say sprint running, not spring running.
Thanks VAS. Do you see hypertrophy with this kind of workout?
I’ve been doing ~100m sprints lately, but I can’t do more than 4 all-out before I feel nauseous. I’m up from 3 a couple of months ago.
If you haven’t done this type of workout before, then yes, you will see increased muscle size
Since Lactate Acid production induces and HGH response, that brings up the question, the more lactic acid you produce the better? Is the HGH release the same whether you produce a little or a lot of lactic acid? There has got to be a level of diminishing returns, where you can’t recover fast enough from all the lactic acid biuld up to make any extra HGH worth it? Anyone have any ideas or sources on this? Thanks.
Doesn’t the conversion from pyruvate to lactate occur in the glycolytic pathway, aka the type of exercise that requires carbs. However if there is not a dose response relationship and there is a certain baseline or threshold level achievable within primarily Beta-oxidative or PCr pathways then you’re in luck.
