Activity specific measured and estimated EE for Shoes and Actical device
| Activity | Shoes (17) | Actical (19) | ||||
|---|---|---|---|---|---|---|
| Meas EE (kcal) | Est EE (kcal) | RMSE (%) | Meas EE (kcal) | Est EE (kcal) | RMSE (%) | |
| Sit | 198.8 (13.1) | 197.6 (11.7) | 10.4 | 80.6 (3.4) | 95.2 (5.0) | 28.5 |
| Stand | 53.0 (8.6) | 52.8 (8.1) | 12.6 | 66.5 (4.8) | 65.2 (4.9) | 16.9 |
| Walk | 181.6 (14.9) | 181.9 (14.3) | 8.8 | 123.8 (11.0) | 143.6 (14.9) | 31.6 |
| Cycle | 67.7 (8.0) | 67.2 (7.7) | 14.8 | 59.1 (3.5) | 21.9 (2.1)a | 54.5 |
Mean (SE) of room-measured (Meas) and device-estimated (Est) EE for the shoe and Actical devices. Estimated EE for the Actical was from the group-specific regression without cycling and include specified sit, stand (standing and sweeping), walk (level and uphill) and cycling, but do not include the free-living time period. Measured EE values for each activity differ due to different protocols (not all participants completed all activities), sample sizes and participants for each device.
