How Endocrine Disruptors Affect Athletes and How to Minimize Exposure

Athletes, due to their high physical demands, must pay special attention to reducing exposure to these compounds found in everyday life. But what exactly are endocrine disruptors?

What Are Endocrine Disruptors?

Endocrine disruptors are chemical substances that, once inside the body, alter hormonal balance by interfering with the endocrine system. These compounds can mimic, block, or modify the action of natural hormones, causing negative effects on the body. They are found in everyday products such as plastics, pesticides, cleaning products, cosmetics, and even some foods, making exposure to them quite common.

Types of Endocrine Disruptors

1. Bisphenol A (BPA)

Where it is found: Primarily in plastics, such as reusable water bottles, food containers, and the inner lining of some cans.

Health effects: BPA can mimic the effects of estrogen in the body, disrupting hormonal balance. In athletes, this can reduce muscle-building efficiency and impair muscle recovery after intense workouts.

2. Phthalates

Where they are found: Common components in flexible plastics (such as food packaging, sports equipment, and some gym gear), as well as in personal hygiene products like shampoos, lotions, and perfumes.

Health effects: They can alter testosterone levels and affect fat metabolism, reducing energy efficiency and potentially decreasing endurance during exercise.

3. Parabens

Where they are found: Used as preservatives in cosmetics, personal care products, shampoos, and some processed foods.

Health effects: Parabens also mimic estrogen in the body and can cause hormonal disruptions. In athletes, this could reduce performance by affecting hormonal balance and, in the long term, may impair reproductive health.

4. Pesticides (such as DDT or glyphosate)

Where they are found: In some non-organic foods, particularly fruits and vegetables.

Health effects: Pesticides can interfere with hormonal and metabolic function, affecting energy metabolism and, in some cases, bone density. This can make athletes more prone to fatigue and injuries.

5. Perfluoroalkyls (PFAS)

Where they are found: In water- and stain-resistant products, such as sportswear, mountain gear, fast-food wrappers, and non-stick cookware.

Health effects: These compounds can accumulate in the body and disrupt thyroid function and weight regulation. This is particularly relevant for athletes, as impaired thyroid function can affect metabolism and energy levels, hindering performance and recovery.

6. Dioxins

Where they are found: Byproducts of some industrial processes, present in meats, fish, and dairy products.

Health effects: Dioxins can weaken the immune system and disrupt hormonal levels. For athletes, this could mean a compromised immune system, increasing the risk of illnesses that interfere with training and competitions.

How Do Endocrine Disruptors Affect Athletes' Health?

For athletes, the impact of endocrine disruptors can be even more noticeable and harmful. Below are some of the most relevant effects:

Impaired Physical Performance

Hormones are essential for metabolism and muscle growth. Exposure to endocrine disruptors can reduce the efficiency of these functions, affecting the ability to gain muscle mass or recover after intense training.

Interference with Energy Metabolism

Some endocrine disruptors influence how the body metabolizes glucose and stores fat. This can lead to premature fatigue, reduced endurance, and difficulty in efficiently using energy during exercise.

Hormonal Imbalance

Disruptors can affect key hormones such as testosterone, cortisol, and estrogen. For athletes, this not only impacts muscle mass but also concentration, motivation, and emotional well-being.

Increased Risk of Injury

The endocrine system also influences bone density and tissue recovery. Prolonged exposure to these compounds could weaken bones or make muscles and tendons more susceptible to injury.

Immune System Problems

Endocrine disruptors can weaken the immune system, making athletes more prone to infections and illnesses that affect performance and keep them away from physical activity for extended periods.

How to Minimize Exposure to Endocrine Disruptors

To reduce exposure to these compounds, athletes can take the following measures:

  • Choose fresh, unprocessed foods.
  • Use glass or stainless steel containers instead of plastics.
  • Avoid excessive use of chemical cleaning products.
  • Check the labels of cosmetics and personal care products to avoid suspicious ingredients like parabens or phthalates.
