Exercise, Exercise, Exercise
Benefits– Improved Cardiovascular Health– Glycemic Control– Cancer prevention and treatment (breast,
prostate)– Smoking cessation– Decreased risk of symptomatic gallstones– Psychological well-being

Exercise Guidelines
For healthy adults under age 65– At least 30 minutes of exercise most days of the
week
How many people in the U.S meet this goal?– Less than 50%

Why?
Common reasons given for not exercising– Lack of time– Boring or monotonous nature of exercise routine– Discomfort associated with exercise (fatigue,
muscle aches, etc. . .)

Music
How music helps?– Reduces sensations of fatigue– Improves mood state– Influences psychomotor arousal– Encourages synchronization
![Page 6: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/6.jpg)
Rating of Perceived Exertion (RPE)
RPE is a rating of how heavy or strenuous an activity feels
Ranges from 6 – 20 – 6 is no exertion at all– 20 is maximal exertion
Listening to music while exercising reduces the RPE
![Page 7: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/7.jpg)
Synchronization
Moving in synchrony to the beat of the music (stepping, pedaling, etc. . .)
Beats per minute (BPM) of the song For example
– Power walking (115-139 BPM)– Jogging/running (147-160 BPM)– Stair climbing (124-128 BPM)
![Page 8: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/8.jpg)
Synchronous vs. Asynchronous
Asynchronous: exercising while passively listening to music, not moving to the beat
Very few studies have been done comparing synchronous to asynchronous exercise
![Page 9: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/9.jpg)
Our study
Goal– to evaluate the effect of synchronous vs.
asynchronous exercise on RPE and overall physical activity in adults who participate in regular exercise (over a 6 week course)
![Page 10: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/10.jpg)
Hypotheses
Synchronous exercise with music will reduce the RPE and improve affect compared with asynchronous exercise with music
Instruction in synchronous exercise with music motivates the participant to exercise more frequently than with asynchronous exercise

Inclusion Criteria
Plan to enroll 46 participants Adult employees of Georgetown University
(20-55 years of age) Engage in regular physical activity of at least
2 exercise sessions per week (80 mins per week) of light to moderate exercise
Listen to music while exercising

![Page 13: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/13.jpg)
Study Set-Up
6 week study Testing/Monitoring:
– Exercise stress test (Georgetown Cardiology department)
– Supervised exercise sessions weekly (on elliptical machine for a 50-55 minute session each week)
Heart rate monitor RPE at 15, 30 and 45 minutes Post-session questionnaires
![Page 14: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/14.jpg)
Study Set-Up
Kenz Lifecorder Plus Accelerometer (advanced pedometer)– Records steps, when there is an increase in
activity, activity time and calories
Post-Session Questionnaires– Physical Activity Affect Scale (PAAS)– Intrinsic Motivation Inventory (IMI)
![Page 15: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/15.jpg)
Control Group
Introductory lecture (60 mins) Encourage patients to exercise as frequently
as they would like with a minimum of once per week
Exercise diary – Duration, RPE during the last 10 mins
![Page 16: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/16.jpg)
Intervention Group
Introductory lecture and instruction on synchronous exercise
MP3 music player– 28 playlists with a variety of songs (45-55 mins
duration)– Laminated cards of each playlist with instructions
(BPM, location of the beat – drum, guitar)
![Page 17: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/17.jpg)
Intervention Group
Encourage patients to exercise as frequently as they would like with a minimum of once per week
Exercise diary – Duration, RPE during the last 10 mins
![Page 18: Impact of Two Methods of Listening to Music During Exercise ...](https://reader036.fdocuments.net/reader036/viewer/2022062300/555105a7b4c90501448b5322/html5/thumbnails/18.jpg)
Primary and Secondary Outcomes
Primary– Change in RPE from baseline at 6 weeks– Comparison between groups
Secondary– Difference in total activity time between groups– Difference in heart rate– Difference in affect, interest/enjoyment

Stay Tuned
Kick-off September 2008 (rolling admissions) Last group of participants will likely complete
study in November/December 2008 Then, Data Analysis. . .
