  1. Impact of Two Methods of Listening to Music During Exercise on Perceived Exertion and Overall Physical Activity Uha Reddy, M.D.

  2. 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

  3. 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%

  4. 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. . .)

  5. Music • How music helps? • Reduces sensations of fatigue • Improves mood state • Influences psychomotor arousal • Encourages synchronization

  6. 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

  7. 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)

  8. 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

  9. 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)

  10. 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

  11. 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

  12. Exclusion Criteria • Major medical condition which prevents regular exercise • Use of Beta Blocker medication • Participation in varsity sports

  13. 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

  14. 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)

  15. 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

  16. 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)

  17. 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

  18. 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

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