Muscle Type DNA Test
Home DNA Test Kit for Muscle Type
A Home DNA test to show if your Muscles are suited to Power or Endurance Sports.
Your muscle type and development is controlled by your genetic makeup, which means that if two people train and eat in exactly the same way, their muscles and sports performance will develop differently, depending on their DNA.
Our new Muscle Type DNA test kit shows whether you are predisposed to producing powerful, explosive type muscles, or whether your muscles are built for endurance. Knowing this about your body will help you decide the type of sports that you are best suited to, and the type of exercise that your body responds to best. It gives you a better understanding and guidance on how to optimise your training and boosts your motivation.
The summary below shows you how easy it is to take your finger-prick blood sample, run the test and then interpret your results.
How does it work? Well, it’s down to a gene called ACTN3, which is responsible for making a protein called Actinin 3 found in your muscle fibres. There are two types of muscle fibres in our bodies; slow twitch and fast twitch. The slow twitch muscle fibres are very efficient and can work continuously for long periods of time, whereas fast twitch fibres are good at generating the short, explosive bursts of power needed in sports such as sprinting and weight lifting. The Actinin 3 protein is found almost exclusively in fast twitch muscle fibres.
There are variants of the ACTN3 gene and it can either be active or inactive depending on the variant you have. If ACTN3 is inactive, it means that your muscles have more of an endurance profile. They are better able to use oxygen in energy production, which is important when your muscles need to work over long periods of time, as in cycling or marathons. If your ACTN3 gene is active you have the fast twitch muscle fibres needed for explosive muscle, which is important in fast and power sports such as sprint, weight lifting etc. Further information about Muscle Types and genetic control is available here
Everything you need for the test is included in the kit, including easy to follow instructions, a swab and a return envelope.
To take the test simply:
- Rinse your mouth with water
- Open the box, which contains a cotton swab in a plastic tube and an instruction leaflet. Carefully remove the sticker including the analysis code from the package leaflet and attach it to the paper/plastic package that contains the cotton bud. Open the upper part of the package and pull out the cotton swab.
- Insert the swab into your mouth and rub the cotton end of the swab against the inside of your cheek.
- Place the cotton swab in its packaging and then into the kit box and seal it. Then place the swab in its packaging into the Freepost* addressed envelope supplied, and post it back to us for testing.
Please leave 7-10 days for our laboratory to test your sample. You can check the status of your test and obtain your test results, using the website address and your test's unique code number provided with the test.

About Muscle Types
Different genes, different muscles
Are you training for long distance running or cycling? Or are you looking for the explosive power needed for the 100-metre sprint or weight-lifting? Information about your muscle properties provides you with the information to choose the sports to which you are best suited and to optimise your training by knowing how your muscles will react. Since muscle development is controlled by your genetic makeup, it means that if two people train and eat in exactly the same way, their muscles and performance will develop differently, depending on their gene type.
The ACTN 3 gene and Muscle Type
The major protein components of skeletal muscle are Actin and Myosin that are arranged together in filaments called myofibrils. The Actin filaments in the myofibrils are stabilised by Actin Binding Proteins or Actinins that separate the filaments allowing them to glide between each other during muscle contraction. This muscle is made up of two types of fibres: slow twitch and fast twitch. Whereas slow twitch muscle fibres are very efficient and can work continuously for long periods, it is your fast twitch fibres that are responsible for generating the short, explosive bursts of power needed in sports such as sprinting and weight lifting.
There are two types of Actinins in the body; Actinin 2 and Actinin 3, which are controlled by the ACTN2 and ACTN3 genes. The ACTN3 is the gene responsible for making Actinin 3, which is found almost exclusively in fast twitch muscle fibres.
The gene exists in two different versions with the ‘C’ base in the DNA code being substituted for a ‘T’ base. The ACTN3 gene version that you have determines how much Actinin 3 protein you have present in your fast twitch muscle fibres.
The C base version, more often known as the R allele, results in a fully functioning ACTN3 gene that produces lots of the Actinin 3 protein. The alternative T base version, known as the X allele, puts a premature stop to the growing protein chain, resulting in a non-functional form of Actinin 3 protein. Studies have shown that the presence of Actinin 3 is associated with an improvement in muscle strength and sprint performance. As a result, sprint and power athletes almost always have at least one copy of the R allele.
Having the alternative XX genotype may give you a different kind of advantage, as studies have shown that the frequency of the X version is significantly higher in endurance athletes. This suggests the X version provides an advantage for slow, efficient muscle performance. It means that your muscles have more of an endurance profile and are better able to use oxygen in energy production. This is important when your muscles need to work for long periods of time as in sports, such as cycling or marathon running.
Muscle Type Test – Frequently Asked Questions
What is meant by 'Muscle Type'?
Muscle is made up of two types of fibres: slow twitch and fast twitch. Whereas slow twitch muscle fibres are very efficient and can work continuously for long periods, it is your fast twitch fibres that are responsible for generating the short, explosive bursts of power needed in sports such as sprinting and weight lifting. This is controlled by your genetic make-up
Why is knowing my Muscle Type useful?
Information about your muscle properties provides you with the information to choose the sports to which you are best suited and to optimise your training by knowing how your muscles will react..
What does the Muscle Type test provide?
Our test is a DNA test that identifies if your carry the R or X allele of the ACTN 3 gene. If you have the R version you produce a lot of active Actinin 3 protein, whereas if you have the X allele you produce non-function Actinin 3 protein.
How accurate is the test?
Your DNA sample is analysed in a laboratory and the result is 99.5% accurate.
Who should take this test?
If you are actively involved in a sport, knowing your muscle type will help you understand your body and optimise your training and motivation. If you are considering taking up a sport it will help you decide the type to which you are best suited..
How is the sample for the test taken?
A simple saliva sample is taken with the special cotton swab provided.
Where can I find the instructions for how to take the sample?
You will find the instructions on the tab surrounding the box. Open the tab on the side of the box on which are printed; “instructions open here”.
How is the sample sent to the laboratory?
Simply remove the parts of the box containing the instructions and the display hook on top of the box by tearing along its perforated edges. To send your sample swab to our laboratory for testing, simply place the swab in the plastic packaging in the addressed envelope provided to return it to us prepaid.
How do I get my result? How accurate is the test?
Your test result can be downloaded from the Dynamic Code website (https://www.dynamiccode.com/en/get-test-result) using the unique code provided in the kit.
Is everything I need for the test included in the kit?
Yes, everything you need to take the test is included in the kit; instructions, swab, a return envelope and a unique code to get your result from the Dynamic Code website.
