Guess what, the latest DNA tests requiring just a cheek swab or saliva sample can help you find a more effective workout for your body.
The ability to build muscle lies in your genes. Specifically, people with the R version of the ACTN3 gene are more likely to develop fast-twitch muscle fibres with the right training, making them better at generating short bursts of strength or speed, such as in sprints. Studies have also shown that the R version of the gene leads to increased growth of muscle mass when strength training. Those without the R version of the gene would need to tweak their workouts in order to build muscle. For example, lifting moderately heavy weights for longer sets, and increasing their protein intake.
Sophisticated lab tests that were once reserved for professional athletes have now gone mainstream, with new companies offering fuss-free DNA test kits that can essentially tell you if your body is built for endurance sports or heavy lifting, and give you instructions on changing your lifestyle habits for better health – all with a simple cheek swab.
How DNA test kits work
The process is simple. It begins by picking up a test kit in-store or ordering it online and have it sent to your home. For saliva tests, take a saliva sample using the swab provided, and mail it back to the company for testing. The advice you get back is what differs between companies, as each has its own method for translating your results into a plan of action.
Are they legit?
According to Dr Rehal Bhojani, a family and sports medicine specialist at the Memorial Herman Medical Group in Sugar Land, Texas, it is worth having testing done to unearth any obstacles to your training and make appropriate adjustments to your workout regimen. Always read the small print and check the testing companies’ websites for the qualifications of their experts. Ask for studies that support the recommendations you receive, and don’t hesitate to get a second opinion from your doctor on any results that concern you.
