Following VO2max determination, maximal cardiac output (Q(max)), maximal stroke volume (SVmax), and maximal arteriovenous O-2 difference (a-vO(2diff_max)) were analysed. Short-interval-(short-HIIT), long-interval (long-HIIT), alternating work-rate continuous (alter-HIT), constant work-rate continuous (const-HIT), and sprint interval (SIT) sessions were per-formed on separate days with iso-effort and iso-time methods. Time spent (t(spent)) at > 95% of VO2max was the highest in long-HIIT (p < 0.05). The t(spent) at > 90% of Qmax was higher in alter-HIT than long-HIIT and SIT (p < 0.05), while there was no significant difference for t(spent) at > 90% of SVmax amongst high-intensity trainings. The t(spent) at > 90% of a-vO(2diff_max) was higher in short-HIIT and long-HIIT than other modalities (p < 0.05). It can be said that continuous modalities seem to have a higher potential to improve central part of VO2max, while interval modalities may be better to develop peripheral component.en10.1016/j.resp.2022.103910info:eu-repo/semantics/closedAccessAerobic powerCardiac outputNitrous-oxide rebreathingStroke volumeSprint IntervalVo2 MaxPhysiological-ResponsesMuscle DeoxygenationExercise IntensityIntermittent RunsAerobic PowerStroke VolumeTime SpentVelocityArticle302WOS:0008059685000012-s2.0-8512842551935405332Q2Q3
