What makes an elite athlete?

Elite performance is often reached by that rare perfect mix of nature and nurture. With StartLine, you’ll learn more than has previously been possible about the genetic traits of thousands of elite athletes.

With the DNAFit StartLine database, we are highlighting the frequency of certain genetic profiles that occur more in elite athletes than in the general population.

A collection of some of the world’s greatest sports talent

DNAFit works with some of the greatest athletes in the world to create the StartLine project, a mission to uncover the genetics of elite performance.

Discover how common your height and genetic profile are amongst more than 8,000 elite athletes in 5 different types of sports, including endurance running, sprinting, team sports, strength and speed.


The StartLine database

Since DNAFit began in 2013, we’ve taken cutting edge science out of the laboratory and into the hands of tens of thousands of people, helping them understand how their DNA affects their response to exercise and nutrition changes, to change the way we train and eat, one DNA sample at a time.

So how do we stand out? We’ve built the largest anonymized genetic database of elite athletes to help us answer the question that so many of us have asked: what makes an elite athlete so elite?

In addition to creating the StartLine database, we also work to make sure your results are backed by science—and science only. To produce your results, we review hundreds of studies, include the most researched genes, and require each analyzed gene to pass a strict inclusion protocol before affecting results

The science

Your athletic potential is largely determined by how often you exercise, the type of training you do, your body type, and how much you enjoy competing in specific sports. Genetic variants have a small impact on your overall fitness and athletic potential, and do not guarantee that you will be a better athlete.

DNAFit analyzed the DNA and height of elite-level athletes to find common correlations. Elite performance is the result of more than just genetic factors—ability, training, perseverance and enjoyment all factor into elite athleticism. Startline lets you compare the genetic component of athleticism to their database of top athletes to see how you stack up.


Environment and how often you exercise plays a large role in athletic and fitness potential. Individual genetic variants play a very small role.

  • Genetic associations are made by looking at large populations of people. Average trends observed in populations may not be true for individuals.
  • Your DNA results do not determine or limit your ability to play or compete in sports.

How it works

Get access to the best and latest in DNA discovery. It takes just 3 simple steps.

Order and we’ll send a DNA kit to your home

Order StartLine and Helix sends you a DNA collection kit, which includes everything you need to get sequenced.

Provide a saliva sample and get sequenced

Register your DNA kit, provide a small saliva sample, and drop it in the mail using the provided pre-paid shipping box you get in your kit.

Receive your StartLine results

After Helix sequences your DNA from your saliva, you’ll get an email from DNAFit to view your results when they’re ready.

The Helix DNA kit

To capture the information stored in your DNA so it can be used for this product, we need to collect a small, one-time saliva sample from you. This kit has everything you need to provide that sample from the comfort of your own home, and you’ll never have to provide another.

  • A unique Kit ID you’ll use to register your kit

  • Saliva collection tube, cap, and printed instructions

  • A small bag and prepaid box to send your saliva sample to our lab

Have a question about ordering or sequencing?


  • Will StartLine tell me what sport I’ll be good at?

    No. StartLine will not tell you any information about what sports you will or won’t be good at. There’s no evidence that this tool can be used for for genetic talent identification, prediction, or potential.

  • I play a sport. Will StartLine tell me how to train the sport I play?

    No. StartLine will help you discover how common both your genotype results and your height are amongst elite athletes in different sporting disciplines.

  • How does DNAFit classify an athlete as elite for the StartLine database?

    Every athlete in the StartLine database has competed at either continental, world or olympic level championships in their respective sport.

  • Can I know the names of the athletes in the database?

    The StartLine database is anonymized and aggregated to protect the identities of the athletes, you’ll see the average profile of elite athletes for each category.

  • Why are StartLine results more accurate for certain people?

    Genetic associations used by this product were originally discovered in European populations and may or may not be applicable to people from a different background.

  • Do I have to get sequenced to use this product?

    Yes. In order to use StartLine, you need to be sequenced by Helix. To ensure the quality and accuracy of the genetic information used for this service, products in the Helix marketplace do not accept genetic data from outside sources. And, once you’ve been sequenced by Helix, you can purchase more DNA-powered products from a variety of categories like fitness, nutrition, entertainment, and more—all without having to get sequenced again.

  • How does Helix provide my DNA information to DNAFit? Is it shared with anyone else?

    Your DNA information is stored securely by Helix. When sequencing is complete, Helix only sends the relevant DNA information needed by DNAFit to generate your results. We do not share your DNA information with anyone without your permission. We always maintain high standards when it comes to the security and privacy of your DNA information.

  • How do I learn more about how DNAFit uses my information?

    You can learn more in the DNAFit Privacy PolicyTerms of Service, and Product Consent.

  • How do I view my results?

    DNAFit will send you an email when your results are ready to be viewed online.
