Experimental procedure
Participants were randomly assigned, using For all participants, the During the second session of trial (Block 3 session 2), participants in the control group did not receive any feedback, while the ViF group received visual feedback for peak force value and SM force–time profile after each trial. Participants in the S-A group were asked to estimate their own applied total peak force in newtons just after the execution of each SM trial, and to indicate if this value was on target (correct: ± 10%), too low (> 10%) or too high (> 10%). After the estimation, participants in the S-A group also received visual feedback for peak force value and SM force–time profile. The first experimental session included a third block for all participants. This third block of 6 trials was conducted to assess SM performance following the intervention or control session of three groups; it included 6 trials (randomized target force of 450 N or 800 N) without any feedback regarding the participant’s performance.
