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
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%
slide4
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
Music
  • How music helps?
    • Reduces sensations of fatigue
    • Improves mood state
    • Influences psychomotor arousal
    • Encourages synchronization
rating of perceived exertion rpe
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
synchronization
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)
synchronous vs asynchronous
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
our study
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)
hypotheses
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
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
exclusion criteria
Exclusion Criteria
  • Major medical condition which prevents regular exercise
  • Use of Beta Blocker medication
  • Participation in varsity sports
study set up
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
study set up1
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)
control group
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
intervention group
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)
intervention group1
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
primary and secondary outcomes
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
Stay Tuned
  • Kick-off September 2008 (rolling admissions)
  • Last group of participants will likely complete study in November/December 2008
  • Then, Data Analysis. . .
