(A) Depiction of the target matching task. The isometric knee extension force generated by the participant animates the yellow box to ascend vertically to match the green target box. Each trial lasted 5.0 s and was followed by a 5.0 s rest period. If the participant successfully matched the target, the trial ended early and any additional time was added to the 5.0 s of rest. A successful match occurred when the box representing the participant's isometric force was inside the target box for 0.3 s. (B) Depiction of the custom‐built pneumatic force transducer that was positioned just proximal to the lateral malleolus of the participant.
