The effect of adaptation on the ratio between maximum grip force and maximum load force. a Mean and ± SE peak ratio across participants in all force-field trials for the three groups of g = − 100 (red), g = 0 (yellow), and g = 100 (blue). Shaded gray regions indicate the trials that were used for the statistical analysis. b Mean and ± SE of peak ratio measure in the two stages of Adaptation: Early – 3 first force-field trials, and Late – 3 last force-field trials. The dots represents the data from each participant. *p < 0.05, **p < 0.01, ***p < 0.001. c and d are as in (a) and (b) for all force channel trials in Adaptation. e Mean and ± SE of the last three force channel trials (dashed bar) and all force-field trials that were performed between these force channel trials (solid bar). Colors are as in (a), and the dots represents the data from each participant. *p < 0.05, **p < 0.01, ***p < 0.001
