  Purpose
The investigators propose to test the effects of an 8-week supervised, site-based, group yoga intervention on cognition and functional fitness in older adults. The SAY Exercise study will compare the yoga group to a stretching group to determine if the program improves attention and cognition, reduces functional limitations, enhances functional performance in everyday activities, as well as psychological health in sedentary older adults between 55-80 years of age. The investigators also propose to assess heart rate variability using a 3-lead EKG and salivary cortisol levels to understand the moderators of the yoga-cognition relationship.

Further study details as provided by Edward McAuley, University of Illinois at Urbana-Champaign:

Primary Outcome Measures:
  • Changes in cognition as assessed by a neuropsychological battery of computer based and paper pencil tests from baseline to 8 weeks [ Time Frame: Baseline - 8 week ]
    Participants will complete a neuropsychological battery of tasks assessing memory, attention, decision making at baseline (before beginning the program) and at week 8 (after completing the exercise program).


Secondary Outcome Measures:
  • Change in functional fitness from baseline to 8 weeks [ Time Frame: Baseline - 8 week ]
    Participants will complete a battery of physical function tests assessing balance, flexibility, strength and mobility at baseline and week 8.

  • Change in psychosocial outcomes from baseline to 8 weeks [ Time Frame: Baseline - 8 week ]
    Participants will complete a packet of questionnaires assessing self-esteem, postitive and negative affect including anxiety and depression, self-efficacy and other psychosocial outcomes.

  • Change in salivary cortisol from baseline to 8 weeks [ Time Frame: Baseline - week 8 ]
    Participants will be providing a small saliva sample via a passive drool into a vial. The compound of interest is cortisol (an indicator of body stress).

  • Change in heart rate variability from baseline to 8-weeks [ Time Frame: Baseline - 8 week ]
    The EKG for each participant will also be recorded in response to a 5 minute unpaced (normal) breathing and 5-minute paced (set to a metronome) breathing. All participants will complete these assessments at baseline and week 8.


Enrollment: 118
Study Start Date: May 2012
Study Completion Date: March 2013
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Yoga Condition
Participants will be instructed to learn yoga postures as well as yoga based breathing and meditative practices by certified yoga instructors. Primary Hatha yoga postures will be performed using props like yoga mats, blocks, belts and blankets. Classes will be held 3 times a week for 8 weeks.
Behavioral: Yoga Condition
Classes lasting one hour, held 3 times per week for 8 weeks.
Active Comparator: Stretching Condition
Exercises focusing on stretching and strengthening for all muscle groups will be performed at one-hour long sessions held 3 times a week for 8 weeks. Classes are led by trained exercise specialists.
Behavioral: Stretching Condition
Classes lasting one hour, held 3 times per week for 8 weeks.
