Physiological and Perceptual Effects of Music on Resting Metabolic Rate (RMR)

Study Overview
=================
Brief Summary
-----------------
The objective of the study is to determine whether music has any effect on resting metabolic rate (RMR), which is the amount of energy expended at rest. There is currently conflicting research on how music affects RMR. One problem with RMR testing is that participants often fall asleep during the test. There can be a 5-10% difference in the metabolic rate between rest and sleep. If no change in RMR is observed, playing music during an RMR test could be a potential strategy to prevent participants from falling asleep. Participants will undergo RMR measurements while listening to no music, relaxing classical music, and self-selected classical music.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Daily Resting Metabolic Rate | RMR will be measured via indirect calorimetry (Parvomedics TrueOne system) | Participants will be randomized to three consecutive 15-minute trials involving listening to no music, classical music, or self-selected relaxing music. RMR will be measured continuously over each 15 min trial. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Heart rate | Heart rate will be measured with a Polar chest strap monitor | Participants will be randomized to three consecutive 15-minute trials involving listening to no music, classical music, or self-selected relaxing music. Heart rate will be measured continuously over each 15 min trial. | 
| Excited/bored scale | Participants rate on a 0-9 Likert scale how bored or excited they are. | Participants will be randomized to three consecutive 15-minute trials involving listening to no music, classical music, or self-selected relaxing music. Levels of boredom/excitement will be measured at the end of each 15 min trial. | 
| Sleepiness scale | Participants rate on a 0-9 Likert scale how sleepy they are. | Participants will be randomized to three consecutive 15-minute trials involving listening to no music, classical music, or self-selected relaxing music. Levels of sleepiness will be measured at the end of each 15 min trial. |
