Wilcoxon rank-sum tests were performed on the age and LQ data, which are shown as mean (SD). A Fisher's exact test was performed on the sex data (M, male; F, female). NS, No significant difference (p > 0.05) between the left-arm-trained and right-arm-trained groups. Note that the number of participants in Experiment 1 includes both 16 participants tested in our previous work (Yokoi et al., 2011) and a newly recruited group of 16 participants (the data from the other 9 participants, which were not used for the analysis, are excluded from this table).
