Relative Energy Deficiency – Sports, or RED-S, is one of the biggest emerging themes within sports nutrition. It is more than just a matter of insufficient calorie intake and it affects both males and females. It may also strongly contribute to over-reaching and overtraining. The top researchers in this field are conducting an international survey and need your help.
Relative Energy Deficiency in Sport (RED-S) – a concept identified and supported by the International Olympic Committee (IOC) – characterizes a range of negative health (impaired endocrine function, bone health, illness and injury, potentially elevated protein requirements) and performance (endurance and strength) outcomes that result from chronic (>weeks to months) low energy availability (EA). Despite wide recognition of its significance for athlete health and performance, our ability to correctly assess and diagnose RED-S remains poor. Furthermore, awareness of RED-S among elite athletes, coaches and physicians remains poor.
In order to enhance our understanding on various RED-S risk factors and to improve our ability to screen athletes for RED-S, we are distributing a questionnaire (20-30 min) that asks athletes questions around potential RED-S signs and symptoms.
With the questionnaire we are targeting athletes, female and male, recreational to high performance, able bodied and para-athletes, ages >15 years old.
Yes that means you Pez fans!
Please take part in the questionnaire in the language of your choice below!
What is in it for athletes?
RED-S concerns high performance junior and senior athletes around the world, where effects are seen beyond the degree of success at major championships, including the cost of health care and long-term consequences for athletes diagnosed with RED-S. The results of these three studies will: 1) inform us of the best parameters to use in the early diagnosis, and management of RED-S; 2) provide information of the prevalence and severity of the problem across sports, and in females and males, at various athlete levels as well as produce global prevalence data on RED-S; 3) provide further information and education on the risks of long-term RED-S and of the ways in which the athlete can avoid developing RED-S. We hope these outcomes will inform improved RED-S diagnoses and ultimately the health and performance of athletes in the future.
