Resumo The objectives of this study were: a) to determine, in a cross-sectional manner, the effect of aerobic training on the peak oxygen uptake (<img border=0 id=_x0000_i1026 src=../../img/revistas/rbme/v9n4/a04img01.gif align=absmiddle>O2peak), the intensity at <img border=0 id=_x0000_i1027 src=../../img/revistas/rbme/v9n4/a04img01.gif align=absmiddle>O2peak (I<img border=0 id=_x0000_i1028 src=../../img/revistas/rbme/v9n4/a04img01.gif align=absmiddle>O2peak) and the anaerobic threshold (AnT) during running and cycling; and b) to verify if the transference of the training effects are dependent on the analized type of exercise or physiological index. Eleven untrained males (UN), nine endurance cyclists (EC), seven endurance runners (ER), and nine triathletes (TR) were submitted, on separate days, to incremental tests until voluntary exhaustion on a mechanical braked cycle ergometer and on a treadmill. The values of <img border=0 id=_x0000_i1029 src=../../img/revistas/rbme/v9n4/a04img01.gif align=absmiddle>O2peak (ml.kg-1.min-1) obtained in running and cycle ergometer (ER = 68.8 ± 6.3 and 62.0 ± 5.0; EC = 60.5 ± 8.0 and 67.6 ± 7.6; TR = 64.5 ± 4.8 and 61.0 ± 4.1; UN = 43.5 ± 7.0 and 36.7 ± 5.6; respectively) were higher in the group that presented specific training in the modality. The UN group presented the lower values of <img border=0 id=_x0000_i1030 src=../../img/revistas/rbme/v9n4/a04img01.gif align=absmiddle>O2peak, regardless of the type of exercise. This same behavior was observed for the AnT (ml.kg-1.min-1) determined in running and cycle ergometer (ER = 56.8 ± 6.9 and 44.8 ± 5.7; EC = 51.2 ± 5.2 and 57.6 ± 7.1; TR = 56.5 ± 5.1 and 49.0 ± 4.8; UN = 33.2 ± 4.2 and 22.6 ± 3.7; respectively). It can be concluded that the transference of the training effects seems to be only partial, independently of the index (<img border=0 id=_x0000_i1031 src=../../img/revistas/rbme/v9n4/a04img01.gif align=absmiddle>O2peak, I<img border=0 id=_x0000_i1032 src=../../img/revistas/rbme/v9n4/a04img01.gif align=absmiddle>O2peak or AnT) or exercise type (running or cycling). In relation to the indices, the specificity of training seems to be less present in the <img border=0 id=_x0000_i1033 src=../../img/revistas/rbme/v9n4/a04img01.gif align=absmiddle>O2peak than in the I<img border=0 id=_x0000_i1034 src=../../img/revistas/rbme/v9n4/a04img01.gif align=absmiddle>O2peak and the AnT.
