About this study

The Active Older Adults prospective cohort study examines the effects of a park-based fitness program on cardiovascular fitness outcomes for older adults (aged 50 years and older). Active Older Adults is designed to provide older adults of all fitness levels with physical activity, and aims to promote participant's abilities to maintain independent lifestyles. It is a low-cost, evidence-based group exercise and falls-prevention program. The program entails one-hour sessions two or three times per week including aerobic workout, strength training, balance and flexibility exercise delivered online or in-person. Data are collected at eight Miami Dade Department of Parks, Recreation and Open Spaces (MDPROS) park locations where the program is offered every four months (fall, winter, spring).

Behavioral

The program entails one-hour sessions two or three times per week including aerobic workout, strength training, balance and flexibility exercise delivered online or in-person. Miami-Dade Parks and Recreation is the sponsor of the Active Older Adults prospective cohort study. Duke is conducting a secondary data analysis on data collected as part of the Active Older Adults study.

Primary outcomes

  1. Change in Body mass index (height and weight)

    Time frame: Baseline, 12 months, 36 months

  2. Change in blood pressure

    Time frame: Baseline, 12 months, 36 months

  3. Change in arm strength

    Time frame: Baseline, 12 months, 36 months

    Participant arm strength is measured as the total number of arm curls performed in 30 seconds. Participants are seated in a chair while holding a dumbbell or cuff weight (5lb for women and 8lb for men) wrapped around their right or left wrist (the left wrist is employed when the right wrist is impractical).

  4. Change in leg strength

    Time frame: Baseline, 12 months, 36 months

    Leg strength is assessed as the number of chair stands a person could complete in 30 seconds. For one chair stand, participants get up from their seats (with assistance if necessary) and then sit back down.

  5. Change in mobility

    Time frame: Baseline, 12 months, 36 months

    Mobility is measured as the time spent in an Eight-Foot-Up-and-Go test. Participants start seated in a chair, and are instructed to stand up, quickly circle a cone placed eight feet in front of the chair, and then sit back down in the chair. The stopwatch will start when the person fully stands up from the chair and stops when the person sits back down into the chair (recorded in seconds).
