are you really suitable for running

Even in the same gym or running group, people may face these questions: Why does someone lose weight faster than me with the same amount of exercise? Why am I more prone to ligament injuries? Why can't I persist to the end of a long run?

The reason might be simple: genes determine that you lose weight slower, have a higher risk of ligament injuries, and are not naturally suited for endurance running. In short, genes affect exercise outcomes, and you might be doing a lot of ineffective work.

Genesand their relationship with exercise

Genes are segments of DNA with hereditary effects, supporting the basic structure and function of life, storing all information about race, blood type, reproduction, and growth. Genes influence protein expression, thereby affecting physical constitution. For example, the FTO gene on chromosome 16 is associated with obesity, also known as the 'obesity gene.' People with FTO gene variations have a 70% higher chance of obesity if both alleles are mutated, and a 30% higher chance if only one allele is mutated.

This gene is the most studied and confirmed obesity susceptibility gene to date. If a specific point on the FTO gene shows a TT type (mutation), the effectiveness of exercise will be slower, and rapid weight loss attempts will be counterproductive.

The type of exercise suitable for a person depends on their genes.

We usually divide exercise into strength-based and endurance-based. The former requires more explosive power, such as sprinting or weightlifting; the latter requires more endurance, such as the currently popular marathon.

For example, why can't a sprint champion participate in long-distance running? Isn't it all running? It relates to the muscle composition of sprinters. Muscles are composed of fiber-like tissues, which can be divided into slow-twitch and fast-twitch fibers based on thickness, oxygen utilization, and energy production speed. Top sprinters and weightlifters can have up to 90% fast-twitch fibers.

Fast-twitch fibers have a weak ability to utilize oxygen and accumulate lactic acid during strength exercises, causing muscle soreness and fatigue. People with a high proportion of fast-twitch fibers may be weaker in long-duration endurance exercises.

Therefore, for some people, muscle pain from long-distance running may not be a good sign; it indicates that they are not suited for this type of exercise.

So, how are muscle tissues related to genes? For example, a variation in the ACTN3 gene promotes the production of fast-twitch muscle fibers, providing explosive power. People with this genotype may find activities like weightlifting more suitable for body shaping.

What is exercise gene testing?

In 2016, Greg, the long jump champion at the Rio Olympics, customized a more scientific training plan based on his gene test results, perfectly maximizing his potential. This became a landmark event for exercise gene testing. Although not everyone will compete in the Olympics, personalized exercise plans are indeed a trend.Through gene testing, we can lose weight or complete training more scientifically and efficiently.

Recently, the well-known consumer gene testing company '23Mofang' launched a gene test specifically targeting exercise ability—'Dongyin.' Luo Yi, a national-level athlete who currently runs his own fitness studio, is also a user of 23Mofang.He believes that for the fitness community, gene testing results can be quickly applied to their daily training.

​

Take 23Mofang's exercise gene test as an example. Besides 'exercise weight loss effectiveness' and 'muscle composition,' it also includes diet metabolism, exercise injury, and exercise psychology, covering almost the entire exercise process.

Diet metabolism test results answer what to eat before and after exercise. Because even if you exercise hard, eating the wrong foods will still prevent you from losing weight.As for 'exercise injury': if the test results show a high risk of Achilles tendon injury, then preparing a pair of cushioned running shoes is a must. These seemingly simple actions are supported by genetic science details. Extracting a person's genes has also become easier, requiring only two milliliters of saliva.

Before conquering your body, understand your chromosomes. This fitness black technology is indeed exciting.
