Some people seem to make rapid progress when strength training, while others naturally excel in endurance sports such as running, swimming or cycling. Even when following a similar training plan, the results can be very different.

Does this mean that some people are born with a greater predisposition for strength or endurance? The answer is more complex than it may seem. Athletic performance depends on multiple factors, including training, nutrition, recovery and experience, but genetics also plays an important role in how our bodies respond to exercise.

Understanding this predisposition does not determine how far an athlete can go, but it can help better understand their abilities and personalise their training plan.

What is the difference between strength and endurance?

Strength and endurance are two fundamental physical abilities, although they serve different functions within the body.

Strength is the ability to generate muscular force to perform high-intensity movements over a short period of time. It is essential in activities such as weightlifting, sprinting and many team sports, where explosive efforts are required.

Endurance, on the other hand, is the ability to sustain physical effort over a longer period while delaying the onset of fatigue. It is particularly important in activities such as running, cycling, swimming and triathlon.

However, these abilities are not mutually exclusive. Most sports require a combination of both, and each can be improved through training. What differs from one person to another is how easily the body adapts to each type of physical effort.

 

 

Why Do Some People Respond Better to Training Than Others?

It is a common situation: two people follow almost the same training programme, yet achieve different results.

This happens because the body's adaptation to exercise depends on many different factors acting together, including:

• The type, intensity and frequency of training.
• Nutrition and nutritional status.
• Sleep quality and recovery.
• Age and overall health.
• Previous sporting experience.
• Genetic predisposition.

For this reason, some people build strength more easily, while others respond better to endurance training or require more time to recover after exercise.

 

How Does Genetics Influence Athletic Performance?

Genetics does not determine athletic success, and there is no single "sports gene." Physical performance is a complex trait influenced by many different genes, together with environmental factors such as training and lifestyle.

However, scientific research has identified genetic variants associated with different aspects of physical performance, including:

• Response to strength training.
• Adaptation to endurance exercise.
• Muscle recovery after exercise.
• Energy metabolism.
• Processes involved in inflammation and tissue repair.

This information cannot predict an individual's performance, but it can help better understand how the body responds to exercise and support a more personalised training strategy.

 

How Can You Find Out Whether You Are More Predisposed to Strength or Endurance?

Today, genetic studies can analyse variants associated with athletic performance to better understand how the body responds to training.

These studies do not replace professional guidance from coaches or healthcare professionals, nor do they determine which sport a person should practise. However, they can provide valuable information about training response, recovery and energy metabolism, helping to adapt training programmes and nutritional strategies to each individual's characteristics.

 

 

SportChip: A Genetic Study to Personalise Your Training

SportChip is Laboratorio Echevarne's genetic study designed to support athletic performance. It analyses 52 genes related to three key areas: sports nutrition, physical performance, and factors associated with injury risk and inflammation. Based on this information, the report provides personalised recommendations to help tailor training and nutritional strategies according to each individual's characteristics.

Since DNA remains stable throughout life, this analysis only needs to be performed once. Its results should always be interpreted alongside other factors such as training, nutrition, recovery and personal sporting goals.

 

FAQs

Why do two people get different results from the same training programme?

Even if two people follow exactly the same training plan, their results may differ. This is because the body's response to exercise depends on many factors, including age, physical condition, nutrition, recovery, sporting experience and genetic predisposition. All of these influence how effectively the body adapts to training.

Can someone be good at both strength and endurance sports?

Yes. Strength and endurance are not mutually exclusive, and both can be improved through training. It is common for someone to progress more easily in one area than the other, but most sports require a combination of both to achieve optimal performance.

How can I find out whether I have a greater predisposition for strength or endurance?

Sports genetic studies analyse variants associated with different aspects of physical performance, including responses to both strength and endurance training. This information does not predict athletic success, but it can help better understand how the body responds to exercise and support a more personalised training plan, always alongside factors such as nutrition, recovery and sporting goals.

Can a genetic study tell me which sport I should practise?

No. A genetic study does not determine which sport is best suited to an individual, nor can it predict athletic performance. What it can provide is information about characteristics related to training response, recovery and energy metabolism, which may help personalise physical preparation.

Do I need to take the genetic test more than once?

No. DNA remains stable throughout life, so this type of analysis generally only needs to be carried out once. The results can continue to be used to adapt training strategies throughout different stages of life or when pursuing new sporting goals.

 

 

In Summary

There is no single answer to whether someone is "more suited to strength or endurance." Both abilities can be developed through training and depend on many different factors. However, genetics is one of the pieces that helps explain why each person's body responds differently to exercise.

Understanding this information can help better understand individual abilities and move towards a more personalised training approach, while recognising that athletic performance is the result of the combination of genetics, training, nutrition, recovery and consistency.
