Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Allocation Method

RANDOMIZED

Intervention Model

SINGLE_GROUP

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Nutrition education

Intervention Type 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.

Control group

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

Group Type NO_INTERVENTION
