Our DNA is a genetic blueprint
DNA is present in almost every cell in your body. A strand of DNA is composed of a sequence of molecules called nucleotides. There 4 types of nucleotides, each named by their one letter symbols: A (adenine), T (thymine), G (guanine), and C (cytosine). Thus, a piece of DNA could look something like this: AGATTCAA. Sequences of these nucleotides creates a gene; which serves as a template for the production of functional proteins, humans have approximately 21,000 genes. Changes in the sequencing of nucleotides causes mutations leading to variation between humans, changes in the number and length of genes are what causes variation amongst any type of living organism.
What is DNA testing?
By taking a sample of your blood or saliva scientists are able grow and multiply your DNA through a process called a polymerase chain reaction. Modern technology has allowed us to be able to identify specific genes and assess any mutations responsible for certain physiological factors. Mutations can occur at random, but environmental and hereditary factors and impact the risk of developing a genetic mutation.
For example: Myostatin; a protein responsible for the inhibition of muscle growth and differentiation, is encoded by the MSTN gene. A rare mutation in this gene, usually inherited, can cause a myostatin deficiency, causing dangerous levels of unregulated muscle growth.
How DNA testing can improve a training program
If you've been training for years, it's likely you've tried many different types and methods of training. You've discovered your optimum rep ranges for growth or that you excel with explosive exercises. If this is the case, then you've also probably wasted sessions where the method of training just wasn't working with your body. By having a DNA test, you can identify certain physiological predisposition, helping focus on certain weaknesses, reducing the risk of injury and adapting your training to maximize gains.
Variations of COL51 and TNC genes impacts the risk of an achilles injury
Variations of MCT1 gene impacts lactic acid clearing and affects levels of fatigue
Variations of ACE and ACTN3 genes impacts muscle force production and endurance capacity
It's important to know these genetic predispositions to so trainers can incorporate different aspects of fitness to maximize progression. Higher risk of achilles injury? Work on strengthening calf muscles and ankle stabilizers. Low lactate clearing capacity? Work on increasing aerobic capabilities. And so on.
Whether you're a fitness newbie or seasoned gym go-er, learning more about your DNA and genetic make up will bring more awareness about your body and can help you along your fitness journey.
