AI-Supported Digital Coaching And Cardiorespiratory Fitness In Male University Students
Sponsor: Transilvania University of Brasov
Summary
This study evaluated whether AI-supported digital coaching combined with Samsung Health-based activity monitoring could improve cardiorespiratory fitness and physical activity in male university students compared with standard Samsung Health monitoring. In this single-center randomized controlled trial, 312 male university students were assigned in a 1:1 ratio to approximately 10 weeks of either AI-supported digital coaching or standard activity monitoring. The AI-supported intervention provided adaptive daily step goals, activity coaching, progress feedback, and recovery recommendations based on recent activity, while the control group used standard monitoring without AI-supported coaching. The primary outcome was estimated maximal oxygen uptake (VO2max) derived from the Cooper 12-minute test. Physical activity was also evaluated using daily step counts collected through the study activity-monitoring workflow.

Interventions
AI-supported digital coaching with Samsung Health-based activity monitoring
Participants received approximately 10 weeks of Samsung Health-based activity monitoring combined with research-configured AI-supported digital coaching. The intervention provided adaptive daily step targets, real-time coaching and goal adjustment, weekly progress summaries and insight cards, and recovery or rest-day recommendations based on recent activity. Android participants received the configured functions through the research Samsung Health environment. For iOS participants, activity data were synchronized through the study workflow using Apple HealthKit where necessary, and equivalent coaching was delivered through a research-administered web dashboard. Research staff provided technical support but did not manually alter AI recommendations or provide individualized exercise coaching.
Standard Samsung Health activity monitoring
Participants used standard Samsung Health monitoring for approximately 10 weeks, including step counting, activity rings, and generic weekly reports. Research-configured AI-supported coaching was disabled for the control condition. Research staff provided standardized technical support, but no individualized exercise coaching or study-provided exercise program was delivered.
