Brief Summary

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). Duke will perform a secondary analysis of the data collected as part of the Active Older Adults prospective cohort study run by Miami-Dade County Parks and Recreation.

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).

Arm && Interventions

Group	Intervention	Description
Active Older Adults	Active older Adults	Body mass index (height and weight), blood pressure and pulse, arm and leg strength and mobility

Primary Outcome Measures

Name	Time	Method
Change in Body mass index (height and weight)	Baseline, 12 months, 36 months
Change in blood pressure	Baseline, 12 months, 36 months
Change in arm strength	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).
Change in leg strength	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.
Change in mobility	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).
