The objective of the study is to determine the impacts of a 2-week relaxing music intervention on stress, anxiety, and gut symptoms in individuals who regularly perform structured aerobic exercise. Gut symptoms like bloating, reflux, cramping, nausea, etc. are relatively common during prolonged aerobic exercise. In addition, previous research has established that levels of anxiety and stress are associated with a higher occurrence of these gut symptoms. Relaxing music has reduced anxiety in certain populations, but currently, no studies are available on its effects on anxiety, stress, and gut symptoms in people who regularly do aerobic exercise.
