Knowledge of the female athlete triad and relative energy deficiency in sport among female cross-country athletes and support staff
Open accessAbstract
Context: Female endurance athletes exhibit an increased risk of the female athlete triad (Triad) and relative energy deficiency in sport (RED-S). The triad and RED-S are conditions that involve the health and performance consequences of low energy availability. Few authors of studies to date have assessed the knowledge that athletes, coaches, and athletic trainers (ATs) have regarding the Triad or RED-S. Proper education has been shown to be effective in increasing knowledge of sports medicine concerns for athletes, yet no known continuing education programs for the Triad or RED-S exist at collegiate institutions. Objective: To assess the knowledge, confidence, and educational impact of identifying, screening, treating, and preventing the Triad or RED-S. Design: Cross-sectional study. Setting: An evidence-based online survey was developed and administered via Qualtrics. Patients or Other Participants: Female collegiate cross-country athletes (n = 275, age = 20 ± 1 years), collegiate cross-country coaches (n = 55, age = 34 ± 9 years), and ATs working with cross-country teams (n = 30, age = 36 ± 11 years). Main Outcome Measure(s): Knowledge, confidence, and educational impact scores were assessed among groups using analysis of variance. Independent t tests were calculated to determine differences in impact scores between people who had or had not received education on the topic. Results: Female cross-country athletes' total knowledge, confidence, and educational impact scores (mean scores = 25.00 ± 5.27, 95.42 ± 28.83, and 18.81 ± 7.05, respectively) were different from those of coaches (mean scores = 26.92 ± 5.02, 111.35 ± 24.14, and 22.41 ± 6.33, respectively) and ATs (mean scores = 28.66 ± 4.02, 117.67 ± 22.53, and 23.93 ± 5.69, respectively; P < .05). Conclusions: Knowledge, confidence, and educational impact scores regarding Triad or RED-S were lowest in female cross-country athletes and highest in ATs. These findings support the call for education, which should be regarded as the primary tool for increasing knowledge, to improve the prevention and treatment of the Triad or RED-S.

From 2023 international olympic committee's (IOC) consensus statement on relative energy deficiency in sport (REDs) (2023) · cites this paper as [145]
The introduction (page unavailable) reports prior assessments finding gaps in athletic trainers’ knowledge of the female athlete triad, and the Discussion (page unavailable) describes a prior survey in which few trainers identified a key component correctly. The paper does not report a comparable finding about physiotherapists, so it supports only the athletic-trainer part of the claim. (LLM, conf=0.87)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
