ClinConnect Summary

This clinical trial is looking into a condition called Relative Energy Deficiency in Sport (REDs), which can affect the health and performance of athletes, particularly those in sports that require maintaining a lean physique. The study aims to understand how common REDs and eating disorders are among Swedish elite athletes compared to non-elite athletes. Researchers will explore how low energy availability—when athletes don’t get enough calories to support their training and health—impacts their overall well-being and performance.

To participate, athletes should be at a national team level or be non-elite athletes who meet certain criteria, such as not having chronic illnesses, injuries, or being pregnant. Those who join will complete an anonymous online survey, and some may be invited for further assessments to evaluate their eating habits, nutritional status, and health markers. This study is important as it seeks to shed light on the challenges athletes face regarding their energy intake and mental health, ultimately aiming to improve support and care for athletes in Sweden.
