简要总结
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).
详细描述
Participants were randomly divided into two groups with 45 individuals receiving six physical nutrition education lectures, and the remaining 38 participants receiving no nutrition education. Participants completed the The low energy availability in females questionnaire (LEAF-Q), Eating Attitude Test (EAT-26) and Sports Nutrition Knowledge Questionnaire (SNKQ). Energy and nutrient intakes were evaluated thorough 3-day food records, while exercise energy expenditure was assessed using 3-day activity logs. All of the questionnaires were repeated after a 6-months period.
At baseline, the prevalence of LEA among athletes was determined to be 63.8%. In the intervention group, energy availability (EA) and SNKQ scores increased, and LEAF-Q scores decreased significantly (p < 0.05). However, there was no significant change in EAT-26 scores between the two groups. Energy intake, weight, fat free mass and resting metabolic rate has been increased significantly in the intervention group (p < 0,05). These findings suggest that nutrition education proves beneficial in enhancing dietary intake, positively influencing body composition and improving nutrition knowledge, ultimately contributing to increased energy availability in female athletes over the short term.

研究组 & 干预措施
Control group
Control group has not taken any nutrition education but has been filled all of the questionnaires, acitivity logs and food diaries.
Nutrition education intervention group
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.
干预措施: Nutrition education (Behavioral)
结局指标
主要结局
Energy Availability
时间窗: 6 months
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.
Low Energy Availability Questionnaire (LEAF-Q)
时间窗: 6 months
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\[28\].
