What You'll Learn
Testing methods: saliva, blood or other bodily fluids
When it comes to testing muscle DNA, there are a few different testing methods that can be used, each with its own advantages and considerations. Here is an overview of the testing methods using saliva, blood, or other bodily fluids:
Saliva Testing
Saliva testing is a widely used method for genetic testing, offering several benefits. It is a relatively simple and fast procedure that can be performed through self-collection. This means that individuals can collect their saliva samples at home without the need for a qualified person to take the sample. The saliva sample can be obtained by inserting a cotton swab into the mouth and gently swiping it across the cheeks, or by allowing saliva to pool in the mouth and then spitting it into a collection device. It's important to ensure that adequate amounts of saliva are collected, typically around 1.5-2.0 mL. Proper handling and storage of the sample are crucial, and specific guidelines should be followed, such as rinsing the mouth with water beforehand and storing the sample at the appropriate temperature.
Blood Testing
Blood testing is another commonly used method for DNA extraction. Blood contains leukocytes, which are the only blood cells that have a nucleus and contain DNA. A qualified person or phlebotomist is typically required to perform a venous puncture to obtain the blood sample. Once the blood sample is collected, it should be sent to a laboratory for processing and purification of the DNA. Blood testing provides an abundant amount of DNA that is usually of high quality. However, it is important to conduct the tests promptly to prevent any potential deterioration of the cells and DNA.
Other Bodily Fluids
In certain circumstances, DNA testing may be performed using other bodily fluids or sources. For example, sperm analysis is used to check male fertility, including DNA fragmentation. In prenatal diagnosis, DNA samples can be obtained from amniotic fluid or chorionic villi. Additionally, non-invasive prenatal screening can be done by analyzing free fetal DNA present in the mother's blood. Hair root samples are commonly used for forensic analysis and paternity testing, as they contain essential genetic information that can be studied to reveal genetic predispositions and vulnerabilities.
Each testing method has its advantages and applications, and the choice of method depends on the specific requirements and goals of the individual or testing facility. These methods enable access to valuable genetic insights that can inform health, fitness, and disease prevention strategies.

Muscular dystrophy diagnosis
Diagnosing muscular dystrophy can be challenging, but getting an accurate diagnosis as early as possible can help improve the quality of life for those living with the condition. The first step is to see a general practitioner (GP) or a neurologist, who will perform a physical exam and ask about your medical history. If necessary, they may refer you for further tests at a hospital. The GP or neurologist will need to know about any symptoms of muscular dystrophy that you or your child have noticed and when they began to appear.
There are several diagnostic tests that can be used to confirm a diagnosis of muscular dystrophy. One of these is a blood test that can detect elevated levels of creatine kinase, an enzyme released into the bloodstream when muscle fibres deteriorate. Another test is electromyography (EMG), which measures the electrical impulse along nerves, nerve roots, and muscle tissue. A doctor may perform an EMG by inserting a tiny electrode needle through the skin and into the muscle to confirm a diagnosis of muscular dystrophy and to determine the best treatment. Heart-monitoring tests (electrocardiography and echocardiogram) are used to check heart function, especially in people diagnosed with myotonic muscular dystrophy. Lung-monitoring tests are also used to check lung function.
Genetic testing can also be used to diagnose muscular dystrophy by identifying changes in a person's chromosomes, genes, or proteins. This can be done through a blood test, cheek swab, skin biopsy, or muscle biopsy. Analyzing the protein in the muscle can help determine which gene is causing muscular dystrophy and therefore which type of muscular dystrophy is present. For example, people with Duchenne MD and Becker MD have too little of the protein dystrophin in their muscles, and this can be seen through microscopic examination of the muscle tissue. Genetic testing can also be used to identify carriers of muscular dystrophy and to perform prenatal diagnoses.

Predispositions to disease or injury
DNA testing can be used to identify predispositions to disease or injury. This can help individuals tailor their lifestyle to avoid possible health conditions. For example, if a DNA test indicates a predisposition for heart disease, an individual can decrease their consumption of red meat and increase their cardiovascular exercise. Similarly, if a test shows a likelihood of insulin deficiency, an individual can reduce their carbohydrate intake to mitigate this risk.
DNA tests can also reveal an individual's propensity for resistance to insulin. This knowledge can help guide dietary choices, as those with a predisposition for insulin resistance may need to reduce their carbohydrate consumption. Understanding these predispositions can help individuals progress in their exercise routines and modify their plans based on their body's natural tendencies.
In addition to disease risk, DNA testing can also identify an individual's predisposition to certain types of injuries. For example, a test may indicate a higher risk of muscle injuries or joint problems. This knowledge can help individuals take preventative measures to avoid these injuries, such as incorporating specific exercises or stretches into their routine to strengthen vulnerable areas.
The results of a DNA test can also inform individuals about their muscle composition, including the ratio of fast-twitch to slow-twitch muscle fibers. This information can guide the development of an exercise routine that aligns with an individual's recovery abilities, helping them understand how hard they can push themselves and when to stop to avoid overexertion or injury.
Overall, DNA testing for muscle-related predispositions to disease or injury can provide valuable insights to help individuals optimize their health and fitness routines, make informed dietary choices, and take preventative measures to maintain their well-being.

Personalised workout plans
A DNA test can reveal a lot about your muscle composition and how you can optimise your workouts. For example, a test can show whether you have a higher number of fast-twitch or slow-twitch muscle fibres, which can inform the type of exercises you should focus on. If you have more fast-twitch fibres, for instance, you may be better suited to sprinting and power-lifting, whereas those with more slow-twitch fibres may excel in endurance exercises like long-distance running. This can help you create a personalised training program that maximises your strengths and improves your overall fitness.
Additionally, DNA testing can identify predispositions to certain injuries or health conditions. For instance, it may reveal a higher risk of tendon injuries or heart disease, allowing you to take preventative measures such as adjusting your training regimen or diet. This proactive approach can help you avoid potential health issues and create a safer, more effective workout plan.
The insights from DNA testing can also extend to your diet and nutrition. By understanding your genetic makeup, you can learn about vitamin and mineral requirements, as well as any food sensitivities or propensities towards certain health conditions. For example, if you have a variation of the MCT1 gene, you may be advised to include more omega-3 fatty acids in your diet, found in foods like salmon, walnuts, and flax seeds.
Finally, DNA testing can provide a scientific basis for your workout and health goals, giving you a detailed plan to follow. This can include recommendations for specific exercises, nutrition, and even sleep patterns, all tailored to your unique genetic profile. With this information, you can streamline your fitness journey, making more meaningful and effective changes to your lifestyle.

Diet and supplement recommendations
DNAFit, for example, offers tailored diet and exercise plans based on your specific genome. Their recommendations are based on the idea that there is a distinct link between genes and trainability. According to Andrew Steele, the head of product at DNAFit, studies have shown that 50% of the differences in how people respond to the same training program can be attributed to a person’s genetic makeup. One of their customers, who grew up consuming a lot of dairy, was surprised to learn through their DNAFit report that they were lactose intolerant. Another customer learned that they have higher levels of muscle inflammation and fatigue than average, and were advised to eat more foods with omega-3 fatty acids and to expect a longer recovery time from intense workouts.
Genopalate, another DNA testing company, uses genetic variants to create a personalized profile for nutrient digestion and can design meal plans based on a person's genetic profile. They focus on genetic variants related to your ability to digest different nutrients, such as fatty acids or vitamins.
Vitagene, which started as a supplement company, now offers DNA diet test reports that detail how your body will respond to certain foods, while their vitamin report tells you what supplements you should be taking based on your genetic variants.
FitnessGenes offers Muscle Building DNA test reports, which provide personalized insights and recommendations to help you maximize your muscle mass and strength. These reports can help you understand your optimal workout, nutrition, and supplement needs to help you work with your DNA and maximize your muscle-building results.
