Table 2.
Torque steadiness from different submaximal torque levels in the high and low visuomotor feedback tasks.
| High visuomotor feedback | Low visuomotor feedback | |||||
|---|---|---|---|---|---|---|
| 5% MVC | 20% MVC | 40% MVC | 5% MVC | 20% MVC | 40% MVC | |
| Standard deviation [Nm] | 0.058 (0.045) | 0.086 (0.027)a | 0.209 (0.071)a,b | 0.056 (0.037) | 0.072 (0.038)a | 0.180 (0.066)a,b |

Further details of statistical comparisons given in text.
Repeated measures multivariate analysis of variance indicated that high and low visuomotor feedback tasks did not differ from each other and there was no task x torque level interaction. Torque levels did differ from each other.
a
p ≤ 0.05 compared to 5% MVC;
b
p ≤ 0.05 compared to 20% MVC.
