Brief Summary

This study investigates the effects of a series of nutrition education sessions conducted by a registered dietitian on energy availability, various anthropometric measurements, eating attitudes, and sports nutrition knowledge in young female endurance athletes aged 15-18 years (football, basketball, volleyball) who engage in training for more than 10 hours per week (n=83).

Relative Energy Deficiency in Sport

Outcome Measures

Primary Outcomes (2)

• Energy Availability

  Energy availability (EA) is described as the amount of energy left over and available for proper organism functions after the energy used for exercise is subtracted from the calories taken in the diet, by American College of Sports Medicine. It is shown that the young athletes often fail to follow the recommended dietary guidelines for their sport and activity level. Therefore that poses risk for low energy availability (LEA) EA below 30 kcal/kg FFM was considered to be low EA, EA between 30-45 kcal/kg was considered to be reduced and EA\>45 kcal/kg was considered to be optimal.

  6 months

• Low Energy Availability Questionnaire (LEAF-Q)

  The 25-item LEAF-Q was used to assess the risk of LEA. The LEAF-Q has been validated in female athletes aged 18-39 training ≥5 times/week, with findings producing an acceptable sensitivity (78%) and specificity (90%) to classify current energy availability\[28\]. Consistent with the original validation study players completed a paper version of the LEAF-Q to ensure validity and reliability were maintained. Scoring was based on the original validation study, with those who scored ≤7 being classified as 'not at risk' of LEA, and those who scored ≥8 being classified as 'at risk' of LEA\[28\].

Nutrition education intervention group

EXPERIMENTAL

Nutrition education was comprimised of 6 physical face to face 60 minutes sessions which was given every week in a school class. Each session was consisted of a different subject including energy metabolism in sport, energy balance, nutrition before and after training, low energy availability, macro and micronutrients, hydration and supplements. Participants also got written information as a printed booklet in order to be able to take notes under sessions and review after the sessions.

Behavioral: Nutrition education

Control group

NO INTERVENTION

Control group has not taken any nutrition education but has been filled all of the questionnaires, acitivity logs and food diaries.

Interventions

Nutrition education BEHAVIORAL

Fifty participants took 6 physical nutrition education lectures and the other group (n=33) didn't have any nutrition education. Nutrition education was comprimised of 6 physical face to face 60 minutes sessions which was given every week in a school class. Each session was consisted of a different subject including energy metabolism in sport, energy balance, nutrition before and after training, low energy availability, macro and micronutrients, hydration and supplements. Participants also got written information as a printed booklet in order to be able to take notes under sessions and review after the sessions.

Model Details: A total of 83 adolescent female elite athletes from 3 different sport clubs (football n=34, basketball n=16 and volleyball n=33) between 15 and 18 years(mean 17.2 ± 2.0) were included in the study.They were divided into either the intervention or the control groupby simple randomization. Fortyfem participants took 6 physical nutrition education lectures and the other group (n=38) didn't have any nutrition education. All of them filled the LEAF-Q (Low energy availability in athletes questionnaire),EAT-26(Eating Attitude Test)and SNKQ (Sports Nutrition Knowledge Questionnaire).Energy and nutrient intakes were assessed based on 3-day food records. Activity logs were analysed to measure exercise energy expenditure. All of the tests have been repeated after 6 months. Nutrition education was comprised of 6 physical 60 minutes sessions given every week in a school class. Each session was consisted of a different subject. Participants got written information as a printed booklet.
