Canadian researchers launch international RED-S study, post questionnaire open to all athletes

Male and female athletes 15 or older can help researchers from the Canadian Sport Institute Pacific by filling out the questionnaire

Trent Stellingwerff and Ida Heikura of the Canadian Sport Institute Pacific have launched an international study on RED-S (relative energy deficiency in sport), a syndrome that plagues many athletes due to underfuelling and unhealthy weight loss. RED-S has been recognized as a severe issue in the world of sports in recent years, but despite many studies on the matter, specialists still struggle to assess and diagnose it in athletes. Stellingwerff and Heikura (along with other research collaborators from around the world) are reaching out to athletes of all levels, both male and female, aged 15 and older in the hopes of learning more about the issue, and you can help by responding to a questionnaire

What is RED-S? 

RED-S is often found in endurance athletes, and can be caused by overtraining and underfuelling. Many endurance athletes believe they need to be as light and trim as possible to perform at their peak. This belief leads many athletes to underfuel so they hit a certain weight while ramping up their training so that they continue to improve and get faster.

This misguided approach to training and nutrition can lead to a number health problems. Athletes who suffer from RED-S can end up having weaker bones than those who follow healthier nutrition habits, resulting in high rates of stress fractures. In fact, athletes living with RED-S are more than four times more likely to suffer a stress fracture than athletes without RED-S. The issues can also lead to dips in performance and chronic low energy availability. 

Unfortunately, there are still a lot of unknowns surrounding RED-S, and experts’ abilities to assess and diagnose it are nowhere near where they could be. These unknowns also translate to the field of play itself, and although RED-S is becoming a more common topic of conversation in the sporting world, many elite athletes and coaches still don’t know about the syndrome, therefore perpetuating the unhealthy nutrition and training practices that can lead to it. 

RED-S affects both male and female athletes. 

The Canadian Sport Institute Pacific research 

The lack of understanding and awareness of RED-S is why the Canadian Sport Institute Pacific is conducting this research and the survey, which is sponsored by Own the Podium, 94Forward and B2ten.

“A RED-S diagnosis tool, across males and females and across many different sports and athlete ages and abilities, is still not fully available or validated,” Stellingwerff says. “We hope that by gathering extensive global questionnaire based data, and linking that with data collected in Canada — which includes blood work, DXA scans, metabolic tests and more — that we can help our entire global RED-S field take a big step forward in the coming years.”

The survey, as already noted, is open to any athlete who is at least 15 years old. Stellingwerff, Heikura and their collaborators want to hear from males and females, recreational and high performance athletes and able-bodied and para-athletes. The plan is to conduct their research over a number of months, and in that time, the survey will remain open. There are two ways that individuals can help the team in their efforts: firstly, fill out the survey, and once that is complete, share the survey online and with your fellow athletes.
