The initial request for a change in chiropractic technique came from Pro-Strongman Chad Coy of the USA, who previously had been treated for years by sports medicine chiropractors and has been an advocate of the profession. As effective as the side posture is, Coy found that in the middle of a strongman competition, the standard chiropractic adjustment method became detrimental to his overall power and force production. Dr. McDougle surmised that, as with static or ballistic stretching (1,5), the Hoffman’s reflex (or H-reflex as initially presented in 1910), can be significantly affected and reduced. Upon Coy’s request and after years of trial and error, Dr. McDougle has designed a system that avoids induction of the autogenic inhibition of muscles that could also compromise force production in strength sports.

Today, chiropractor Dr. McDougle is known as the “Strongman Doc” due to these revelations of thought, science, and applications that have met with great success. He continues to serve the surrounding counties and patients beyond as those who need help search him out. He consults with strength athletes in other countries as well due to what has been described as the limited nature of understanding of those in control of the medical establishments abroad.
