How many times have you heard the phrase…
“It’s in their DNA.”
DNA is both simple and complicated, always between… Nature AND Nurture
For example, when it comes to eye color, the DNA is very simple, as eye color is 100% determined by Nature.
100% Nature AND 0% Nurture
But as we move on to height, the DNA formula becomes a little more complicated,
as Nature decreases and Nurture increases.
80% Nature AND 20% Nurture
(Nurture involves sleep and nutrition)
Based on the study “Meta-analysis of the heritability of human traits based on fifty years of twin studies” (Journal of Nature Genetics), the meta-analysis of 2,748 studies involving more than 14.5 million pairs of twins found that the average nature-and-nurture influence on most human traits is nearly balanced, with a split of 49% nature and 51% nurture. The analysis also showed that heritability estimates for muscle development and use range from a more complicated split of 30-85% genetic influence (nature) and 15-70% environmental influence (nurture).
More complicated…
Myth: Strength is associated with muscle mass.
Human Truth: Bigger muscles do not equate to bigger strength.
While athletic performance involves more than 250-500 genetic markers, an analysis of 135 genes will provide enough information to write your athletic story based on muscle fiber type, energy use, warrior-type, nutrition, training, recovery, sleep, and detox process.
