Female athlete triad – relative energy deficiency in sport – RED-S – overtraining syndrome – Venn diagram

It would be easy to say relative energy deficiency in sport (RED-S) and overtraining syndrome (OTS) are linked looking at this Venn diagram. However, one major difference is present in that RED-S is a state of chronic low energy availability due to energy intake not meeting your daily needs. While the female athlete triad overlaps with RED-S due to menstrual irregularities and poor bone health, RED-S can impact athletes regardless of gender. Image: iRunFar/Corrine Malcolm
