Previously known as the female athlete triad; the current model expands on the original to include a broader spectrum of symptoms across both genders. Relative Energy Deficiency in Sport refers to symptoms of impaired physiological functioning caused by a mismatch between energy intake (diet) and the energy expended during exercise. Leaving insufficient energy to fuel the functions required by the body a decrease in optimal health or performance ensues.
This mismatch leaves insufficient energy to fuel the functions required by the body which impacts health and performance, health smptoms can appear in non-athletes who also have a mismatched dietary intake to the needs of the body.
Correct wellbeing and sport nutrition programming should fuel for the work required to maintain optimal health and maximise performance.
