Brief summary
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.
Interventions
OTHEREducation
One 45 minute educational session on the role of carbohydrate in exercise
OTHERMetabolic Testing (Exercise) with shared interpreted results
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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Education versus Education plus metabolic testing | 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. | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Education alone | 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. | Within the education only group |
