An interventional study of Education and Metabolic Testing (Exercise) with shared interpreted results in Nutritional Deficiency, sponsored by PepsiCo Global R&D. Completed at 1 site in United States. Open to female participants aged 13 Years to 19 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-16.

Many studies have consistently shown that females across sports under consume carbohydrate. Registered dietitians working with athletes have also reported female athletes chronically under consume carbohydrate. The primary objective of this study is to compare the effectiveness of education versus education plus interpreted individual metabolic (exercise) testing results to change attitudes and beliefs of female athletes regarding carbohydrate intake. The secondary objective is to assess the effectiveness of the education alone on attitudes and beliefs towards consuming carbohydrate in female athletes.
The study hypothesis is that education alone will not significantly impact attitudes and beliefs, and that metabolic testing and the interpretation of the individual results will alter attitudes and beliefs toward carbohydrate intake.

Exclusion Criteria:
Classroom session with slides and videos. Exercise with shared exercise data.
Other: Education · Other: Metabolic Testing (Exercise) with shared interpreted results
Classroom session with slides and videos.
Other: Education
One 45 minute educational session on the role of carbohydrate in exercise
One 20-30 minute session. Treadmill, warm-up, then at increasing intensities for 3-minute intervals wearing a mouthpiece for measurement of respiratory gasses (oxygen consumption, carbon dioxide production). Testing starts with a 3-minute warm-up at 3.4 mph, 1% grade, increasing every 3 minutes until a respiratory exchange ratio of 1.0 is reached or volitional exhaustion
Education versus Education plus metabolic testing
To compare the effectiveness of education alone versus education plus interpreted individual metabolic testing results to change attitudes and beliefs of female athletes regarding carbohydrate intake.
Time frame: Change in Nutrition Attitudes Questionnaire score from Baseline visit to same questionnaire re-taken 2 weeks later. For each questionnaire, a higher score will be correlated to more positive sentiments around carbohydrate intake.
Education alone
Within the education only group
Time frame: Change in Nutrition Attitudes Questionnaire score from Baseline visit to same questionnaire re-taken 2 weeks later. A higher score will be correlated to more positive sentiments around carbohydrate intake.
