Figure 1.
Step counts detected with the Omron pedometer and Fitbit wristband activity monitors during A) treadmill exercise, treadmill walking, and treadmill exercise plus walking combined (total steps: laboratory setting); and B) treadmill exercise, activities of daily living, and treadmill exercise plus activities of daily living (total steps: real-world setting). All measurements significantly different at P< .05.
| Activity type | Omron pedometer | Fitbit wristband monitor |
|---|---|---|
| Number of steps (standard deviation) | ||
| Laboratory setting | ||
| Treadmill exercise | 3,763 (441) | 3,529 (533) |
| Treadmill walking | 6,243 (451) | 5,871 (767) |
| Real-world setting | ||
| Treadmill exercise | 3,763 (441) | 3,529 (533) |
| Activities of daily living | 6,309 (1,850) | 7,695 (1,062) |
The 5 graphs show the difference in steps measured by the Omron hip-worn pedometer and the Fitbit wrist-worn pedometer for treadmill exercise, treadmill walking, and ADL.
