Pacemaker detected active minutes are superior to pedometer-based step counts in measuring the response to physical activity counseling in sedentary older adults

	Pre-Intervention (average hours of active time/day)	Post-12 Week Intervention (average hours of active time/day)	Post-12 Week Maintenance Period (Week 24) (average hours of active time/day)
> 0.8 m/sec (n = 8)	1.57 ± 0.37	2.33 ± 0.48*	2.05 ± 0.48^*
≤ 0.8 m/sec (n = 5)	1.64 ± 0.33	1.67 ± 0.45^†	1.88 ± 0.43

*P < 0.05 vs. Pre-Intervention in those with gait speed > 0.8 m/sec, ^†P < 0.05 vs. gait speed > 0.8 m/sec at the same study time point. Data presented as mean (SD). PDAH- pacemaker derived active hours
