Moreover, Pearson correlation was recruited to determine whether the continuous
data (age, duration of training, motivation, and trait self-control) were correlated or not.
One moderate correlation (r = 0.324, p = 0.002) between pre-test motivation (MO1) and
pre-test cognitive and somatic anxiety (CSA) was found. Therefore, analyses were applied
to two-way repeated ANOVA, except for the variable of CSA, which was applied to
two-way repeated ANCOVA (Table S2)
