Brief Summary
Many athletes anecdotally report modifying their nutritional intake before competition in order to avoid gut problems, but no studies have evaluated whether emotional state impacts tolerance to pre-exercise feeding. Therefore, this study will use movie clips (stressful, horror, and funny/amusing) to induce different mood states and emotions, which will be followed by ingestion of food before endurance running on a treadmill. In addition, metabolic and physiologic responses to mood induction will be evaluated.

Outcome Measures
Primary Outcomes (2)
Total exercise gastrointestinal symptom burden
The severity of several gastrointestinal symptoms will be assessed on a validated 0-10 scale. Ratings will be collected every 5 minutes during a 30-minute treadmill jogging/running test. Scores from every 5-minute collection will be summed to calculate total GI symptom scores.
Total GI symptom burden over a 30-minute jogging/running protocol.
Change in emotion ratings
Anxiety, fear, happiness, amusement, disgust, sadness, and anger on a 0-9 Likert scale. Emotions will be assessed before watching video clips and immediately after watching video clips.
Change in emotion ratings between immediately pre-video and immediately post-video.
Secondary Outcomes (5)
Change over time in exercise heart rate
Heart rate will be measured throughout a 30-minute treadmill jogging/running test. Change over time will be evaluated using mixed ANOVA.
Substrate use
Carbohydrate and fat oxidation rates will be measured during the last 5 min of a 30-minute treadmill jogging/running test.
Feeling Scale
Ratings on the Feeling Scale will be measured at rest before watching video clips and throughout (every 5 min) a subsequent 30-minute treadmill jogging/running test.
Fatigue Scale
Ratings on the Fatigue Scale will be measured at rest before watching video clips and throughout (every 5 min) a subsequent 30-minute treadmill jogging/running test.
Heart rate post-video
Heart rate will be recorded immediately after videos are viewed.
Study Arms (3)
Funny/Amusing Video Clips
EXPERIMENTALParticipants will watch 5-7-min video clips that are meant to be funny/amusing
Horror/Scary Video Clips
EXPERIMENTALParticipants will watch 5-7-min video clips that are meant to be scary
Thrilling/Suspenseful Video Clips
EXPERIMENTALParticipants will watch 5-7-min video clips that are meant to be thrilling/suspenseful
Interventions
Participants watch 5-7 minutes of video clips that are funny/amusing in nature
Participants watch 5-7 minutes of video clips that are scary in nature
Participants watch 5-7 minutes of video clips that are thrilling/suspenseful in nature
