Representative oxygen uptake (\( {\dot{\text{V}}}{\text{O}}_{2} \)) response to moderate-intensity constant-load exercise (a) and group means of time constant (τ) of the fast component during moderate-intensity constant-load exercise (b) before (Pre), 4 weeks after (Mid), and 8 weeks after (Post) cycle training with (BFR group) or without (CON group) blood flow restriction (BFR) (a): \( {\dot{\text{V}}}{\text{O}}_{2} \), BL, the baseline of \( {\dot{\text{V}}}{\text{O}}_{2} \); \( \Delta {\dot{\text{V}}}{\text{O}} {2} \), fast, the asymptotic amplitude of the fast component (the increase in \( {\dot{\text{V}}}{\text{O}}_{2} \) from the baseline to the asymptote of the fast component); \( {\dot{\text{V}}}{\text{O}}_{2} \), fast, the absolute asymptotic amplitude of the fast component (the sum of the baseline and the asymptotic amplitude). (b): Values are expressed as means ± SE. Statistical analysis was performed using a repeated-measures two-way analysis of covariance, followed by Bonferroni's multiple comparisons test. Partial eta squared (ηp2) is the effect size of the interaction and main effects of group and time. *Significant difference from Pre (P < 0.01). †Significant difference between BFR and CON groups at that time point (P < 0.01).
