Rationale for the Feasibility and Acceptability of Smartwatch Technology in an Exercise Regimen (FASTER) study in older individuals

By Hauben J, Luthy J, Nafiu T et al.

BACKGROUND: Less than 15 % of individuals 65+ meet physical activity guidelines for aerobic and muscle-strengthening activities. Thus, in this study we will examine the feasibility and acceptability of utilizing smartwatches among Exercise is Medicine (EIM), a physician referral exercise program, for participants aged 65+ to improve physical activity. METHODS: We will conduct a single-arm trial. Participants will complete an 11-week exercise program combined with a smartwatch, monthly webinars, and two follow-up sessions at 6 and 12 months. Surveys will measure acceptability of the exercise program and the wearable smartwatch. The number of active participants, participant attendance and program completion rates will assess feasibility of the program. SETTING: Ambulatory care clinics affiliated with a medical center and community centers in Central Ohio. DESIGN: Single-arm pilot study. INTERVENTIONS: FASTER will consist of 3 one-on-one and 16 group sessions over 11 weeks in addition to wellness webinars and two follow-up one-on-one sessions 6 and 12 months after program completion. The one-on-one and group sessions will be led by an American College of Sports Medicine (ACSM) certified exercise physiologist with EIM credentials. All participants will receive a Fitbit smartwatch to use throughout the program. OUTCOMES: The primary outcome is the feasibility and acceptability of FASTER. Secondary outcomes are change in physical activity, biometric measures, mental health, and quality of life. DISCUSSION: Incorporating wearable smartwatch technology into a physician referral exercise program may be a novel way to improve physical activity and health in older adults. CLINICAL TRIAL REGISTRATION NUMBER: NCT06287255.
