The purpose of this study is to test whether decreasing sedentary time (time spent sitting) and adding short intervals of brisk walking improves the health of older adults. Other studies have recently shown that when middle-aged adults walk briskly for 2-minutes every 20-minutes their metabolic health is improved. We do not know if a similar exercise prescription would also be effective in older adults. We also do not know how such exercise would compare to 1, continuous brisk walking bout (e.g. 30-minutes).
The main inclusion criteria for this study are:
- Healthy men and women between 60 and 85 years old
- Non-exercisers – you must currently participate in less than 30 minutes of moderate physical activity a day
- You must be a non-smoker
- You must be free from any diagnosed acute or chronic conditions such as diabetes, heart disease and cancer
- You must be free from any orthopedic conditions that may limit your ability to walk briskly
Benefits for study volunteers include:
- Measurement of body composition and bone density
- Measurement of the amount of calories your body burns while at rest – this is known as your resting metabolic rate
- Assessment of metabolic health, including key factors that are important to healthy aging
Frequently asked questions:
- Will I be paid for participating? Yes. If you complete all study visits you will be compensated $325. If you start the study, but do not complete all of the study visits for any reason, you will be paid only for the visits that you completed.
- Where do I go for study testing? All testing sessions will take place on the Anschutz Medical Campus in Aurora, CO.
- How long will I be in the study? Participation in this study should take approximately 2-3 months from the start of the screening process until completion of the study.
