The relationship between oxygen uptake ($\dot{\mathrm{V}}{\mathrm{O}}_2/W$), heart rate (HR), and trait anxiety. a Linear plot of $\dot{\mathrm{V}}{\mathrm{O}}_2/W$ and trait scores. No significant correlation was observed (ρ = 0.209). b Comparison of $\dot{\mathrm{V}}{\mathrm{O}}_2/W$ in HT and in LT. No significant difference was observed in $\dot{\mathrm{V}}{\mathrm{O}}_2/W$. c Linear plots of HR and trait scores. No significant correlation was observed (ρ = −0.047). d Comparison of HR in HT and in LT. No significant difference was observed in HR. Median $\dot{\mathrm{V}}{\mathrm{O}}_2/W$ and HR 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
