WHAT IS RED-s?

In this article, Coach Alan writes about how too little energy for athletes can lead to a negative spiral of health and performance. What is RED-s and how can it affect athletes?

RED-s

A small energy deficit that is planned, timed, and considered in light of an overall training plan may decrease body fat percentage. But where is the tipping point between creating a deliberate deficit in calorie intake to make a planned change in body composition and too much deficit?

Low Energy Availability or LEA is a state that an athlete is in when the body does not have enough energy to support all the physiological functions needed to maintain optimal health. This is particularly common when ‘dieting’ or when increasing training load; this can be more likely in endurance sports with high energy expenditure. ‘Weight’ consideration and ultimately the power to weight conversations are often confused or misinterpreted as a reduced weight can initially be hidden by performance gains which quickly end up in poor health. 

The first point, ‘dieting’, is well known, but what about that second point, ‘increasing training load’? Often as athletes get towards race day or seek higher and more ambitious goals, the drive and motivation and pressure increase, and the search for any way to improve performance can increase, as can the calorie burn with high levels of training. At this point, having the idea to improve body composition leads to a drift in both directions away from optimal calorie consumption. Increasing training load whilst decreasing calorie intake is a sure way to underperform and possibly deteriorate performance. An athlete in this situation would be at risk of performance loss at best and risk of serious illness.

What is RED-s?

In 2014 the International Olympic Committee released a consensus statement regarding RED-s, but what is it?

Relative Energy Deficiency in Sport (or formerly the female triad) is a relative energy deficiency that affects many aspects of physiological function, including metabolic rate, menstrual function, bone health, immunity, protein synthesis, cardiovascular and physiological health.

Warning signs/effects include;

Physiological

  • Lack of three consecutive periods in females or a change to a previously regular menstrual cycle

  • A decline in morning erectile function in male athletes

  • Poor development of muscle mass

  • Difficulties staying warm in the winter and cool in the summer months

  • Downy growth of hair all over the body

  • Constipation or feeling bloated

  • Reduced metabolic rate

Behavioural

  • Pre-occupation and constantly talking about food

  • Poor sleep patterns

  • Restricting or strict control of food intake

  • Overtraining or difficulties taking rest days

Psychological 

  • Irrational behaviour

  • Fear of food and weight restoration

  • Severe anxiety

  • Becoming withdrawn and reclusive

Performance

  • Poor recovery between training sessions

  • Digestive issues –athletes often become constipated and bloated

  • Increase in incidence of illness

  • Decreased endurance and muscle strength

  • Recurrent injuries

  • Decrease in bone health - stress fractures

Ensure you are fuelled with carbohydrates to train and minimise any calorie deficits, especially in hard blocks of training and/or when looking to improve absolute rather than relative performance. Make sure you look after that foundation of nutrition.

Non-binary approach 

Often athletes will talk about making a change in behaviour around nutrition or about creating a calorie deficit. This can often lead to a black and white or binary way of thinking about nutrition, fuelling and food. In reality, what we eat, when we eat and how much we eat varies as much as our training load does. Our approach to training also varies, and as age-group athletes, other demands in our life often dictate changes in our approach to training as well. It is imperative to have a good perspective and flexible approach to training as an age-grouper. The same perspective and flexibility are critical when it comes to nutrition. 

We need a lot of fuel for some days and sessions, and for others, we don’t. On some days, we need to be kind to ourselves because there have been other challenges in our life and that intervals session perhaps should be done easier. On some days, we need to remember that nutrition in any form can also be as much for our mental health as it can be for our physical health. Indeed, some foods have been shown to affect our mental health directly, caffeine, for example, can affect our anxiety levels, and dark chocolate has had links with lower recordings of depressive symptoms. An athlete who is anxious about their calorie counting may consume excess coffee and exclude treats such as dark chocolate and find that their overall health, and performance, suffers. 

Food isn’t just fuel; it’s health and its enjoyment as well. Much like training, however, though if you do zero training, the balance isn’t quite right.

Accuracy

I feel it is also crucial to mention accuracy. Those of you reading this who have had to study statistical analysis or fair testing for science as part of your education or working lives will understand that there can be many variables that can affect readings and affect the perspective given by ‘data’. Data needs to be digested in a firmly understood context and applied in that context. In some situations, it can be all too easy to believe a fundamental piece of data to be accurate and use it vigorously rather than generally and slightly sceptically. When it comes to the accuracy of calorie counting, a little bit of scepticism can be a helpful thing. Simply googling calorie amounts and using MyFitnessPal in conjunction with a gender-based generic calorie amount, even with the calorie burn data from a training device, may be wildly inaccurate in terms of their energy balance calculation. Habitually counting with a significant margin for error can lead to substantial differences between an intended action and an unintended outcome. This considerable difference can lead an athlete down the road of RED-s; Coach Philip has written a little more about the calculations here.

How can you/we avoid RED-s?

  • By taking a holistic approach to nutrition

  • By understanding the energy demands of training and competition

  • By taking a holistic approach to body composition (not ‘weight’)

  • By making athletes aware by writing this blog

  • By writing about the accuracy and calculations in detail

  • By maintaining health before performance mindset

  • Individuals and coaches create an environment and culture that encourages a ‘healthy approach to performance.’

    • This includes language used.

    • This also includes social media follows.

  • Plan out our nutrition for each day as we would training, be organised and ensure that food that is suitable and balanced with our training and life load is prepped for before, during and after training. Often a lack of organisation can mean missed meals or poor choices made, which would be the same as wondering why our body didn’t respond well to a session without a warm-up! Nutrition is part of the training session.
