Superman and Bone Density

The science behind Superman and bone density contains more truth than one might expect. That truth can now be applied through a new, breakthrough technology, explained by inventor and guest author, Dr. John Jaquish.

Bone Density Science & Superman

When I speak to medical practitioners about treating osteoporosis with heavy, multiples of bodyweight loading, I am often asked about research to support my claims. Depending on the sense of humor of my audience, I say, “the research has been published and has been available at the comic book store for the past 75 years.” As physicians look up from their smartphones or lecture notes in bewilderment I explain further:

This year marks the 75th anniversary of one of the most beloved comic book superheroes, Superman. First debuting in 1938, “Action Comics” delivered a character from a planet that was very different from ours. Superman’s planet, Krypton, had much higher gravity than that of Earth. The people from Krypton had no special powers on their planet, but on Earth they were capable of incredible feats of strength and were seemingly invincible. The most recent Superman film, Man of Steel, (2013) stated that the gravity on Krypton was 10 times that of Earth gravity. One reason the character has had so much long-term success may be the significant scientific research that is the basic premise behind Superman.

The Science of Superman and Bone Density

In 1892, Dr. Julius Wolf wrote “The Law of Bone Remodeling.” Dr. Wolff’s research showed the positive effects of multiples of bodyweight/gravity on the density of bone. The more weight/force an individual could load their skeletal system with, the greater bone density would become (Wolff, 1892). This scientific fact is used in the character of Superman. Though more than 100 years has passed since this scientific discovery of Wolff’s Law was made, very little has been done in the medical or exercise science communities, until now.

bioDensity… The Krypton Device

Developed to address my Mother’s osteoporosis, bioDensity was designed specifically to load the body with multiples of bodyweight safely and effectively, delivering a level of “Superman effect” that this level of loading can provide. Though the bioDensity system will not enable people to run “faster than a speeding bullet,” proper use of the system can provide the increase of bone density and strengthening of joints. This degree of compression strengthens the joint capsule by increasing growth of fibrocartilage (Benjamin & Ralphs, 1998). One unexpected result of bioDensity use was a greater activation of muscle tissue. As the bone and joints adapt/grow, a stronger support is made for muscle, and greater force is typically produced from session to session. This coincides with research done illustrating a loading/force production session could have a chronic effect of force increase following a single session (Mookerjee & Ratamess, 1999). Use of the bioDensity system is safe because the force is self-generated, making user comfort the limiter for the amount of load/force used. Between increased bone density, increased joint strength, and increased force production, one can see how multiples of bodyweight loading actually DOES produce “super” results.
