Data are presented as mean ± SD. * p-values are calculated by two-way repeated measures ANOVA, GxT: GroupxTime. ^a–d The superscripts refer to the results of post hoc tests to test the differences between measurements at three time points. ^a Significantly different from pre-intervention (p < 0.01). ^b Significantly different from pre-intervention (p < 0.001). ^c Significantly different from after one session (p < 0.05). ^d Significantly different from pre-intervention (p < 0.05).
