| Inactivity threshold | Inactivity time (% of total time) | |
| Mean | SD | |
| 90% of EMG of standing | 67.5 | 11.9 |
| 1% EMGMVC | 54.5 | 17.1 |
| 2% EMGMVC | 68.2 | 15.4 |
| 5% EMGMVC | 81.4 | 11.9 |
The first row represents results using individually determined threshold below standing activity (mean of four muscle groups) that is compared to the absolute % levels of each individual's EMG amplitude during maximal voluntary contraction (EMGMVC).
