The Influence of Different Mood States and Emotions on the Physiologic, Metabolic, and Perceptual Responses to Feeding Before Exercise

Not Applicable

Recruiting

• Conditions: Cramp, Abdominal; Other Gastrointestinal Disorders
• Interventions: Other: Funny/Amusing Video Clips; Other: Horror/Scary Video Clips; Other: Thrilling/Suspenseful Video Clips

• Registration Number: NCT05217589
• Lead Sponsor: Old Dominion University

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.

Arm && Interventions

Group	Intervention	Description
Funny/Amusing Video Clips	Funny/Amusing Video Clips	Participants will watch 5-7-min video clips that are meant to be funny/amusing
Horror/Scary Video Clips	Horror/Scary Video Clips	Participants will watch 5-7-min video clips that are meant to be scary
Thrilling/Suspenseful Video Clips	Thrilling/Suspenseful Video Clips	Participants will watch 5-7-min video clips that are meant to be thrilling/suspenseful

Primary Outcome Measures

Name	Time	Method
Total exercise gastrointestinal symptom burden	Total GI symptom burden over a 30-minute jogging/running protocol.	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.
Change in emotion ratings	Change in emotion ratings between immediately pre-video and immediately post-video.	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.

Secondary Outcome Measures

Name	Time	Method
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.	Heart rate will be measured with a chest-strap (Polar) monitor.
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.	The Feeling Scale is a bipolar numerical rating scale ranging from -5 to +5, with descriptors of "very bad" at -5, "neutral" at 0, and "very good" at +5.
Heart rate post-video	Heart rate will be recorded immediately after videos are viewed.	Heart rate will be measured with a chest-strap (Polar) monitor.
Substrate use	Carbohydrate and fat oxidation rates will be measured during the last 5 min of a 30-minute treadmill jogging/running test.	Carbohydrate and fat oxidation rates will be estimated from the volumes of oxygen consumption and carbon dioxide production during exercise
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.	The Fatigue Scale is Likert-type scale that ranges from 0 (Not Fatigued at All) to 10 (Total Fatigue).
