Objectives
Narrative objectives1
To compare the effects of two structured interval walking training protocols (1-minute vs. 3-minute alternating fast/slow walking cycles) on walking performance (6-minute walk test distance and speed) in community-dwelling older adults over a 12-week intervention; to examine the relationship between cadence-based exercise intensity accumulation (weekly duration at cadence of at least 105 and at least 120 steps per minute) and improvement in walking performance and functional fitness; and to assess changes in exercise self-efficacy, self-rated health, depressive symptoms, functional fitness, and body composition over the course of the intervention.

Assessment
Primary outcomes
Change in 6-minute walk test (6MWT) distance (meters) and average speed (m/s) from baseline to week 12.
Key secondary outcomes
Weekly duration (minutes) of moderate-intensity walking (cadence at least 105 steps per minute) and vigorous-intensity walking (cadence at least 120 steps per minute) from baseline to week 12; weekly average cadence during fast-walk phase (steps per minute); weekly total step count; weekly average daily step count; change in exercise self-efficacy score, self-rated health score, and depressive symptom score from baseline to week 12; change in functional fitness measures (timed up-and-go test, sit-to-stand test, single-leg stance test, and Short Physical Performance Battery) from baseline to week 12; change in body composition parameters measured by bioelectrical impedance analysis (InBody), including body fat percentage, skeletal muscle mass, and body mass index, from baseline to week 12

Interventions/Control_1
Interval walking training with 1-minute alternating fast and slow walking cycles, guided by real-time cadence feedback via the WalkPacer Pro mobile application. Participants were free to determine their own training frequency and duration, with no prescribed minimum or maximum weekly target; actual weekly duration at moderate intensity (cadence at least 105 steps per minute) and vigorous intensity (cadence at least 120 steps per minute) was recorded via the application. Training was self-administered using the mobile application over a 12-week period.
Interventions/Control_2
Interval walking training with 3-minute alternating fast and slow walking cycles, guided by real-time cadence feedback via the WalkPacer Pro mobile application. Participants were free to determine their own training frequency and duration, with no prescribed minimum or maximum weekly target; actual weekly duration at moderate intensity (cadence at least 105 steps per minute) and vigorous intensity (cadence at least 120 steps per minute) was recorded via the application. Training was self-administered using the mobile application over a 12-week period.
