Summary

In recent years, research teams around the world have developed interventions to educate older adults to use outdoor exercise facilities (OEFs) to improve health outcomes like strength, balance, mobility, PA level, and weight. These interventions employed trainers or therapists to instruct, and monitor exercise training for older adults using the public accessible OEFs. Apart from therapist or trainer-led intervention, an Australian research team developed a mobile application, and social support strategies to help participants to use OEFs to enhance their aerobic and resistance-based PA. A recent local in-depth qualitative study discovered that OEFs in Hong Kong attracted frailer older adults (i.e., those who recovered from a major illness or who has chronic diseases), and their caregivers to use OEFs to support and maintain their daily PA behavior. Some used OEFs to complement their formal rehabilitation sessions. It appears that OEFs in Hong Kong serves as an important health maintenance space for frailer older adults in the city to "age in place", yet educational training related to OEFs has been lacking over the years. Signage besides the exercise equipment has been the only education material for users over the years. A mobile app-based physical activity education intervention will be developed for frail old adults in Hong Kong. The intervention has two components: (1) mobile app; and (2) face-to-face group session that teaches the how to use correctly and safely use OEF in public parks to maintain PA habits. The main objective of this study is to evaluate the feasibility, acceptability, and pilot effectiveness of the 'Outdoor Rehab-Fit' App-based physical activity education intervention. Primary outcomes include recruitment rate, retention rate, attrition rate, attendance, perceived usefulness of the app. Secondary outcomes include exercise self-efficacy, mental well-being, physical activity level. This study adopts a mixed-method design with quantitative and qualitative method. This study is a pilot randomized controlled trial, running for 4 months evaluating of the effectiveness of the mHealth intervention. 40 frail older adults will be randomized into (i) mHealth group or (ii) control group. Quantitative analysis will be adopted to investigate the effectiveness of the 'Outdoor Rehab-Fit' App-based physical activity education intervention on the health outcomes of frail older adults. The qualitative component will consist of semi-structure interviews with the frail older adults to understand the acceptability of the intervention.

Conditions

• Physical Inactivity
• Frailty

Interventions

Type	Name	Description
BEHAVIORAL	mHealth	Participants receive 4 sessions of face-to-face or online delivered workshop on how to use the mobile app "Outdoor Rehab-Fit" to support their daily PA level. In addition to the workshop, participants have to go to public parks to practice what they have learnt from the mobile app.
BEHAVIORAL	Health Talk	Participants receive 4 sessions of face-to-face or online delivered health talks on the benefits different types of modified exercises for frail older adults (chair yoga, seated eight-section brocades, Otago and seated multi-component exercise). Each talk has an experiential session.
