Overview

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.

Interventions

  • Other Funny/Amusing Video Clips
    Participants watch 5-7 minutes of video clips that are funny/amusing in nature
  • Other Horror/Scary Video Clips
    Participants watch 5-7 minutes of video clips that are scary in nature
  • Other Thrilling/Suspenseful Video Clips
    Participants watch 5-7 minutes of video clips that are thrilling/suspenseful in nature

Primary outcome measures

  • Total exercise gastrointestinal symptom burden [Time frame: Total GI symptom burden over a 30-minute jogging/running protocol.]
  • Change in emotion ratings [Time frame: Change in emotion ratings between immediately pre-video and immediately post-video.]
Secondary outcome measures (5)
  • Change over time in exercise heart rate [Time frame: Heart rate will be measured throughout a 30-minute treadmill jogging/running test. Change over time will be evaluated using mixed ANOVA.]
  • Substrate use [Time frame: Carbohydrate and fat oxidation rates will be measured during the last 5 min of a 30-minute treadmill jogging/running test.]
  • Feeling Scale [Time frame: 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 [Time frame: 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 [Time frame: Heart rate will be recorded immediately after videos are viewed.]
