Peak force estimation
±
The percentage of accurate estimations in the S-A group was 50% (1.5 trials accurately estimated over 3) for the 450 N trials and 33% (1 trials accurately estimated over 3) for the 800 N trials. The mean absolute difference between the estimation and the reached peak force was 44.7 (± 37.8) N for the 450 N trials and 60.9 (± 41.5) N for the 800 N trials.
