Results of experiment 1. A: group mean force compensation (±standard error of mean; SE) across trials. B: group mean force profiles (±SE) obtained by averaging individual force profiles aligned to peak speed. Dashed lines are hypothetical, ideal field A compensatory forces calculated from velocity and used as reference. Labels on x-axis reference position in the protocol, with A2 being the 2nd trial in field A, C5 the 5th trial in the clamp phase, etc. Multiple lines per panel are from channels of the different types, respectively. Gray lines and brackets between panels indicate regions represented in this way.
