The relationship between inspiratory time (T I ), expiratory time (T E), and trait anxiety. a Linear plot of T I and trait scores. A significant negative correlation was observed in T I (ρ = −0.622, p < 0.05). b Comparison of T I in HT and in LT. T I in HT was significantly shorter than in LT (**p < 0.01). c Linear plot of T E and trait scores. A significant negative correlation was observed (ρ = −0.631, p < 0.05). d Comparison of T E in HT and in LT. T E in HT was significantly shorter than in LT (*p < 0.05). Median T I and T E in HT and LT were indicated with horizontal bars. The vertical bars indicate the range and the horizontal boundaries of the boxes represent the first and third quartiles
