Understanding Relative Energy Deficiency in Sport (REDs)

September 3, 2024 · In: Pain Science and Healing, Science-Backed Education

When an athlete’s performance begins to falter without an apparent reason, it’s essential to look beyond the physical injuries and consider other potential factors affecting health and performance. Relative Energy Deficiency in Sport (REDs) emerges as a key culprit. This condition stems from an imbalance between energy intake and energy expenditure. However, it leaves a mark not just physically, but psychologically, as well. Athletes experiencing REDs can experience multiple problems throughout the body, which can lead to increased injury risk and can affect mental health. Thankfully, the road to recovery is possible with tailored dietary adjustments and training modification. This post will review the intricate details of REDs, treatment approaches, and prevention strategies to optimize athlete health and performance.

**This is not medical advice. Please consult your medical provider for more information.

relative energy deficiency in sport (REDs)

Understanding the Basics of REDs

Relative Energy Deficiency in Sport (REDs) occurs when the energy you consume does not keep pace with the energy you expend. In other words, you are not taking in enough energy to meet the demands of exercise placed on the body. This imbalance impacts your body’s functions, leading to hormonal imbalance, metabolic rate changes, and other physiological effects. Not only does this affect peak athletic performance, but it can also hinder your ability to maintain optimal health.

REDs doesn’t just pose a risk to your physical wellbeing, but it affects your mental health too. With it can come withering motivation, decreased sports performance, and mood changes.

It’s crucial for both you and your coaches to recognize the signs early on. Look out for unexplained fatigue, recurrent injuries, and an overall decline in athletic performance. These are signs that your body is signaling an imbalance that demands attention. Understanding Relative Energy Deficiency in Sport is not just about preventing the negative impact on sports performance, but protecting your health in the long run.

Relative Energy Deficiency in Sport (REDs) vs Female Athlete Triad

Female Athlete Triad has been known for low bone density, menstrual disturbance, and disordered eating. REDs was formally referred to as “Female Athlete Triad.” It has since been updated to relative energy deficiency in sport to reflect that it occurs in men as well. It was also changed to reflect that it affects more in the body than the original three areas of health described earlier.

REDs exposes more complexities and interconnections of different body systems. REDs encompasses a much broader spectrum of health issues impacting both male and female athletes across a range of sports. It is more than just the female athlete triad’s focus on menstrual function, bone health, and energy availability (as well as the focus on females only). Relative energy deficiency in sport extends into areas like metabolic rate, broader hormonal imbalance, and psychological impact. It relates all of these areas to the overall wellbeing and performance of athletes, both male and female.

Understanding the differences between these conditions helps athletes, coaches, and healthcare providers develop more effective prevention and treatment strategies. While the female athlete triad provided an important starting point, expanding focus to REDs allows for a more inclusive and comprehensive approach to athlete health, ensuring energy balance and nutritional needs are met to support peak performance and reduce injury risk.

The Science Behind REDs

When you push your body to its physical limits when participating in sports, it’s easy to overlook the balance that is needed to keep everything running smoothly. It is easy to blame low energy levels on the fact that you are working very hard, expending energy to ask your body to perform at its absolute best. But what happens when low energy levels become more than just that?

With Relative Energy Deficiency in Sport (REDs), the energy balance is disrupted, resulting in a cascade of physiological effects that can sideline even the most elite athletes. At the core of REDs lies an imbalance between energy intake and the energy expended, leading to a deficit that wreaks havoc on your body. This disequilibrium not only causes alterations in your metabolic rate, but also triggers hormonal imbalances, mood changes, and other problems that can have a profound impact on your physical, emotional, and psychological wellbeing.

Hormonal changes stemming from REDs are significant because they interfere with the functions that are vital for peak performance and overall health. One major consequence is the disruption of reproductive hormones, which can lead to irregular menstrual cycles in female athletes and decreased testosterone levels in males. These hormonal imbalances can affect fertility and bone health in the long run. Moreover, these hormonal imbalances can influence your mental health, potentially leading to feelings of exhaustion, depression, or irritability. The changes in metabolic rate can also make it hard to maintain muscle mass, recover from training, and even increase your risk of injuries.

Understanding the science behind REDs is crucial for athletes, coaches, and healthcare professionals to develop strategies that safeguard athlete health, ensuring that the drive for improved performance does not come at the expense of one’s wellbeing.

Identifying Relative Energy Deficiency in Sport (REDs)

Medical professionals play a crucial role in diagnosis REDs. It is a multidisciplinary approach that ensures a comprehensive understanding of the condition and implementation of treatment targeted to your unique needs. Just as REDs can affect multiple body systems, the treatment approach must be tailored towards the unique signs and symptoms each athlete faces.

Identifying REDs requires a keen eye on both physical and psychological signs and symptoms. It is more than simply noticing a drop in performance or energy. It involves recognizing subtle changes in mood, recovery patterns, dietary habits, and more.

REDs in Different Populations

Relative Energy Deficiency in Sport (REDs), as expressed earlier, can impact athletes across all ages and genders.

For young athletes, the risk of REDs can often be heightened due to growth spurts and increased energy demands characteristic of puberty. Manifestation of symptoms for both male and female athletes might be different. Females, for instance, might face menstrual irregularities and hormonal imbalances. This can often be overlooked in the early stages of REDs. Males, on the other hand, might have a notable decline in testosterone levels, which could manifest as changes affecting muscle mass and strength.

Recognizing gender-specific considerations is paramount in tailoring prevention and treatment strategies. Understanding the differences aid in safeguarding the long term wellbeing and performance of all athletes.

Physical Symptoms of REDs

Much like a car running on an empty tank, an athlete with insufficient energy intake compared to their energy output is on a direct path to physical setbacks. The body, lacking the necessary fuel, can’t repair itself. This sets the stage for recurrent injuries and impaired recovery. Fatigue also sets in more quickly during training and competition.

Further complicating matters is the impact on performance. Energy deficiency doesn’t simply translate to less power. It involves a systemic failure to operate at peak efficiency. Hormonal imbalances that also accompany REDs further contributes to declining performance levels. This establishes a vicious cycle that can be challenging to break without proper intervention.

Physical symptoms of REDs include (but are not limited to):

  • decreased muscle strength
  • earlier onset of fatigue
  • decreased endurance/power performance
  • decreased training response
  • impaired recovery/recurrent injuries
  • impaired growth and development
  • reduced immunity

Psychological Symptoms of REDs

Along with the accompanying physical consequences of REDs, it is important to not overlook the psychological impact, as well.

With a hinderance in physical and athletic performance can come frustration with oneself surrounding performance output. The psychological toll of battling REDs can manifest as decreased motivation, heightened anxiety, and depression.

The secrecy surrounding REDs often leads athletes to navigate these issues alone. A continuous cycle can emerge with both physical and psychological symptoms, one fueling the other. That is why it is so important for healthcare professional, coaches, parents, and athletes all to be aware of the often hidden signs and symptoms of REDs.

Psychological symptoms of REDs include (but are not limited to):

  • mood changes
  • sleep disturbances
  • decreased motivation
  • anxiety/depression
  • difficulty with confidence and self-perception
  • decreased cognitive performance/skill

Nutritional Strategies to Counter REDs

Understanding the depth of dietary adjustments and nutritional strategies becomes crucial with REDs. Understanding energy availability is a start, as this helps determine a good starting place for how much fuel is needed for an individual. The mathematical formula for energy availability (EA) is:

Energy availability = (energy consumed – energy expended)/fat free mass (kg)

However, it is more than just about calories. Restructuring diet to help promote recovery and hormonal balance is also key.

  • Increasing energy intake can counteract the energy deficit at the heart of REDs, focusing on nutrient-dense foods to support metabolic rate and overall health.
  • Strategic meal timing plays a significant role in supporting energy availability, with a focus on surrounding training sessions with adequate nutrition to aid in recovery and performance.
  • Emphasizing dietary quality is paramount, ensuring a balance of macronutrients to support training needs and physiological effects. Think lean proteins, complex carbohydrates, and healthy fats.

These adjustments require patience and guidance from a sports nutritionist or registered dietician. Addressing and preventing REDs through such nutritional strategies not only enhances performance but also protects against the long-term consequences of this condition.

Simply put, FOOD is FUEL. However, the nuance here is that the issue is so much more than overtraining and underfueling.

Further Complications With Nutrition

Eating disorders (EDs) are common in athletes. Consideration should be taken when dealing with REDs as eating disorders can further complicate things. While not all REDs cases involve eating disorders, eating disorders and/or disordered eating and behaviors can trigger REDs. Please speak with a healthcare practitioner or registered dietician if you or someone you know is dealing with an ED or disordered eating.

Training Modifications

Training modifications are crucial when dealing with REDs, especially when paired with nutritional counseling and guidance from a licensed dietician. The modifications made to training should focus around smart adjustments that maintain your athletic performance, while also addressing the risks associated with REDs.

Remember, it is imperative to understand that balancing energy intake with energy expenditure is vital. Training modifications are meant to assist with this. The secret lies in personalizing your regimen and pairing it well with your current dietary intake provided by your dietician. This is why it is extremely important to go through a multidisciplinary approach and have healthcare practitioners, parents, athletes, and coaches all on the same page. By incorporating recovery strategies and ensuring adequate energy balance, you can mitigate the risks of hormonal imbalance and ensure your metabolic rate supports your athletic goals.

On top of that, integrating techniques to monitor progress can help keep a close eye on your health and performance metrics. Timely adjustments can be made quickly if necessary. These training modifications aren’t just about prevention. It is about taking a holistic approach and applying it to multiple areas of an athlete’s life to ensure complete wellbeing.

The Role of Support Systems in Relative Energy Deficiency in Sport

Support systems come in multiple forms. Coaches, nutritionists, and healthcare providers are indispensable in guiding you towards recovery. They must all work cohesively together to help each individual athlete, as no case is exactly alike. These professionals help in devising nutritional and training strategies that ensure adequate energy intake, proposing training modifications that neither compromise performance nor exacerbate REDs.

Along with an athlete’s physiological state, the psychological state is also important. Sports psychologists can serve to assist with issues dealing with performance anxiety, depression, and other issues an athlete may be dealing with. Moreover, a support system can also come from friends and family. With everyone’s support, the path to managing and preventing REDs becomes clearer, allowing athletes to focus on what truly matters – their love for the sport and their performance with it.

Prevention Strategies

The biggest implementation in prevention strategies around Relative Energy Deficiency in sport (REDs) is education. Education for athletes, coaches, and support systems can help safeguard athletes and their wellbeing by recognizing early warning signs.

The next layer of defense is rooted in awareness. Being aware of subtle shifts in performance, injury frequency, and psychological state may be indicative of imbalance. By fostering an environment where discussions around sports nutrition, the physiological effects of energy deficiency, and the intrinsic ties to performance, the groundwork in helping protect against REDs is put in place.

Recovering from REDs

Recovering from REDs requires a multidisciplinary approach that intertwines not just dietary and training adjustments, but mental health support is also crucial. Both physiological and psychological recalibration is needed.

Mental health support is often an underestimated pillar of REDs. It is important to acknowledge the intertwined nature between physical and psychological wellbeing. Finding the guidance and support you need will ensure your wellbeing is holistically nurtured.

TL;DR

Relative Energy Deficiency in Sport (REDs) is an imbalance between energy intake and energy expenditure. There are many different physical and psychological signs and symptoms of REDs, including mood changes, decreased energy and strength, and sleep disturbances. A multidisciplinary approach should be implemented when treating REDs, which may involve training modification and dietary adjustments. Maintaining athlete wellbeing should be the ultimate goal of parents, coaches, healthcare professionals, and athletes alike.

Some of the work does not look like work at all. Some of the work does not look like work at all.

Sometimes it looks like rest. Sometimes it looks like saying no. Sometimes it looks like doing 10 minutes when you wish you could do 60. Sometimes it looks like sitting on the couch and letting the day be small.

If you are someone who has spent your whole life proving you can push through, this part of the work will feel like failure at first. But try looking at it like this instead: it is part of what your nervous system has been asking you for the whole time.

A little reminder ❤️

#chronicpain #nervoussystemawareness #restisimportant #mentalawareness
I am not posting this from the other side of a fla I am not posting this from the other side of a flare. I am posting it from inside one.

For two weeks I have been doing the work I teach… pacing, resting, listening, modifying. None of it has fixed it.

And I have caught myself spiraling into the exact thoughts I would gently redirect a patient out of. “I should know better.” “I am the expert in this.” “What am I doing wrong?”

Here is what this flare has reminded me. Knowing the framework does not exempt you from living inside it. A regulated nervous system is not a permanent state. It is a relationship you keep coming back to. And the moments when nothing is working are not proof you are doing it wrong. They are proof your body is asking for something you have not figured out how to give it yet.

If you are in it too right now, I am right there with you. Tell me what is in your bucket this week. Let’s all share some support with one another.

#nervoussystemhealth #chronicpainawareness #chronicpainsupport #painflare #mindbodyconnection
I did a workout that should have been easy and los I did a workout that should have been easy and lost two weeks to it. Six months ago that same workout was nothing. Nothing about my body broke. My capacity is just being asked to cover more than it used to.

This is the thing I want every woman with chronic pain to understand before she beats herself up one more time. Your nervous system is not separating “the hard workout” from “the rough week at work” from “the night you barely slept.” It is pulling from one pool to handle all of it.

When you stop asking “what should I be able to do” and start asking “what can my body support today,” everything gets easier. Not in a wellness-quote way. In a real, your-actual-life way.
If your bucket has been full for a while, tell me what is in it.

Save this for the next time your body does something you do not understand. You will want the reminder.
