oa South African Journal of Clinical Nutrition - The female athlete triad in student track and field athletes : original research



To explore the female athlete triad components in university track and field athletes, as well as calculate estimated energy availability.

Cross-sectional descriptive study design.
Sixteen volunteer, white, female track and field athletes were recruited from North-West University.
Athletes completed a demographic, health and sport questionnaire; pathogenic body weight control questionnaire; menstrual history questionnaire; four 24-hour dietary recalls and one three-day diet and exercise record form. Body composition and bone mineral density (BMD) were assessed with dual energy X-ray absorptiometry. The bulimia, drive for thinness and body dissatisfaction subscales of the Eating Disorder Inventory, and the cognitive dietary restraint subscale of the Three-Factor Eating Questionnaire, was used to measure disordered eating behaviour. Estimated energy availability was calculated using a three-day dietary and exercise record form completed by the athlete on three heavy training days.
In the total group, 25% had menstrual pattern changes, 62.5% disordered eating behaviour, 73.3% (11/15) low estimated energy availability, and 12.5% reported stress fractures during the past two years. The average estimated energy availability was 18.5 (14.1-40.9) kcal/kg fat-free mass/day. Diet or fat-burning pills were the most popular pathogenic weight-control measures used by 37.5% athletes. Athletes with menstrual pattern changes had lower spine [1.043 (0.975-1.059) vs. 1.166 (1.090-1.234) g/cm2, p-value = 0.043] and femoral neck [0.905 ± 0.045 vs. 1.025 ± 0.027 g/cm2, p-value = 0.042) BMD. Altogether, 87.5% athletes presented with various components of [sentence incomplete in article].
More than two thirds of this group of student track and field athletes had low estimated energy availability and more than three quarters were classified with various combinations of the components of the female athlete triad.
