Cadence and Intensity Across the Adult Lifespan (CADENCE-Adults)

Brief Summary:
The purpose of this study is to determine and link cadence (the number of steps taken in a minute) to the intensity of physical activity (e.g. low-, moderate- and vigorous-intensity) in adults (21-85 years old). The investigators anticipate that cadence will be a good indicator of exercise intensity. Identifying how cadence relates to activity intensity will allow for physical activity guidelines to be communicated to the public in a manner that is more accessible to the lay person.

Study Type : Observational
Estimated Enrollment : 260 participants
Observational Model: Cohort
Time Perspective: Cross-Sectional
Official Title: Cadence and Intensity Across the Adult Lifespan
Study Start Date : December 2015
Estimated Primary Completion Date : December 2019
Estimated Study Completion Date : December 2019

Young Adult
80 Adults 21-40 years of age: 10 Male and 10 Female in each 5 year increment (21-25, 26-30, 31-35, 36-40).
Middle Aged Adults
80 Adults 41-60 years of age: 10 Male and 10 Female in each 5 year increment (41-45, 46-50, 51-55, 56-60).
Older Adults
100 Adults 61-85 years of age: 10 Male and 10 Female in each 5 year increment (61-65, 66-69, 70-75, 76-80, 81-85).

Primary Outcome Measures :
  1. Cadence (steps/min) as assessed by observation (hand tallied counts) of cadence [ Time Frame: Cross-sectional data; single time point, throughout study, up to 5 years ]
    The identification of cadence value cut-points associated with low, moderate and vigorous activity.

  2. Monitor validation (difference in steps/min compared to observation/hand tallied counts) [ Time Frame: Cross-sectional data; single time point, throughout study, up to 5 years ]
    Compare the ability of different activity monitors to accurately measure cadence

Ages Eligible for Study:   21 Years to 85 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
A convenience sample from the surrounding community of male and females 21-85 years will be recruited as participants. Specifically, 10 men and 10 women for each 5-year age-group category (21-25, 26-30, 31-35, etc.) will be collected.

Inclusion Criteria:

  • Adults between ages 21-85 years, able to ambulate on a treadmill (self-report)

Exclusion Criteria:

  • BMI less than 18.5 or more than 40kg/m^2
  • Having smoked tobacco within the past 6 months
  • wheelchair bound, or conditions that prevent normal ambulation
  • Resting systolic blood pressure > 159 mm HG, or diastolic blood pressure > 99 mm HG
  • Hospitalization for mental illness within the past 5 years (for the 41-60 and 61-85 year old cohorts this was change to "within the past 1 year").
  • Any condition/medication that may affect heart rate response to exercise testing.
  • Previous history of, or clinical symptoms or signs of, cardiovascular disease, stroke or transient ischemic attacks, chest pain, unusual dyspnea during physical activity/exercise, severe ankle swelling, or leg pain while walking.
  • Any significant medical condition that may interfere with the study.
  • Previous history of musculoskeletal injuries or problems causing severe pain during physical activity or exercise which interferes with daily activities.
  • Participant has a pacemaker or other implanted medical device (including metal joint replacements).
  • Participant is pregnant.
  • Participant is unable to complete all testing (1 or two sessions, based on risk factors) within a maximal two week period.
  • Individuals wearing a full beard may need to be excluded from the study, as large amounts of facial hair around the mouth and nose interfere with the seal of the device that measures the air you breath. Because of this we are seeking participants that are clean-shaven or with a beard where areas around the nose and mouth are clean-shaven (e.g. goatee).
