| Constant Force | Increasing Force | Decreasing Force | ||||||
|---|---|---|---|---|---|---|---|---|

Values are means ± SD. Average number of motor units (MUs) detected during each trial, and the number of units used in further analysis, for the constant force and two-force trials. MVC, maximal voluntary contraction.
