Growth Hormone Response to Resistance Training

Lots of research has been conducted on how to elicit the greatest growth hormone (GH) response in the body. There are actually several GH isoforms, but by far, the most commonly studied is the 22-kD molecule that consists of 191 amino acids. If you’re attempting to get some more size on your frame, then you should be concerned about your body’s GH response to your lifts.

Rules of Thumb:

  1. GH is maximized via concentric muscle action, specifically.
  2. Men and women have similar GH responses to resistance exercise. However, women naturally have more GH at rest than men do.
  3. The idea the GH response is limited in “older” individuals is a fallacy. GH response is primarily linked to EFFORT, not age.
  4. Planning is crucial. If you are “winging-it” in the gym, you’re probably wasting your time - in terms of muscle growth. Everything is important: sets, reps, intensity, total volume, rest time, exercise selection. So, very difficult (some may say “insane”) set/rep schemes are in order. Ex. 10x10 @ 70% with 2-min rest or 6x15 @ 60% with 3-min rest.

Cocktail trivia you can breakout for your meat-head minded friends: growth hormone is secreted from the anterior pituitary, which receives its “orders” from a neural response initiated by higher brain centers – like the motor cortex – as they react to certain muscle actions.

One last tip: A Cup-O-Strength may be required to make it through 6x15 squats… hey, can’t hurt, right?

A little about me: I've worked in pretty much every corner of the fitness industry for about 10 years. I've had the great fortune of spending most of this time working with gifted athletes at every level. I've also had the great opportunity of designing and conducting research projects, writing occasionally for various publications and blogs, competing in powerlifting, and just generally having a killer time pursuing my passions wherever they may take me. Now I own two businesses: one is an athletic performance training company that I started in 2007 at age 26 and the other is a software company startup that was launched in 2014. Paramount to all the awesomeness of my professional career, is my family. My kids are a thrill and my husband continues to be my most critical and important supporter.
