Detailed Description

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).

Study Population

Active Older Adults is offered in Miami-Dade County (MDC), FL where 40.9% of people older than 65 are sedentary (did not participate in any leisure-time activities, physical activities other than their regular job, during the past month). Within MDC, age-adjusted death rates per 100,000 population (2020-2022) from cardiovascular disease were higher for both Black (291.8.7 vs. 263.4) and Hispanic (179.2 vs. 171.2) residents of MDC vs. statewide, respectively, compared with White (186.2 vs. 198.7) residents. This disparity is particularly relevant for MDC where 69% of people identify as Hispanic or Latino and 17% identify as Black, as opposed to about 19% and 14%, respectively in the United States and 27% and 17% respectively in Florida.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Active Older Adults
Body mass index (height and weight), blood pressure and pulse, arm and leg strength and mobility
Behavioral: Active older Adults
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Body mass index (height and weight)
Time Frame: Baseline, 12 months, 36 months
Baseline, 12 months, 36 months
Change in blood pressure
Time Frame: Baseline, 12 months, 36 months
Baseline, 12 months, 36 months
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).
Baseline, 12 months, 36 months
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.
Baseline, 12 months, 36 months
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).
Baseline, 12 months, 36 months
