Eighteen healthy and sedentary participants were separated by sex, nine men and women (25,20 ± 2,60 years; 22,10 ± 1,80 years and, 77,30 ± 12,30 kg; 58,60 ± 9,60 kg, respectively). An incremental test was realized at treadmill to determine the associated speed to VO2max (vVO2max) and running to exhaustion (Tlim) at vVO2max to determine the VO2 kinetics, with data expressed by average and standard desviation. The VO2max (3,29 ± 0,62 vs 1,90 ± 0,39 L/min) (p&#8804;0,0001); vVO2max (14 ± 2 vs 10 (3) km.h-1) (p<0,0108); amplitude (3 ± 0,70 vs 1,80 ± 0,40 L/min) (p<0,0003) was significantly increased to men. There was not detected a statistic difference between men and women to the constant time [35,80 (22,30) s vs 36,50 (6,60) s] (p<0,2973); Tlim [271 (118) s vs 261 (73) s] (p<0,6849); Target time to achieve VO2max [142,30 (84,50) s vs 175,80 (24,60) s] (p<0,2973); %Tlim to TAVO2max [43,70 (24,40) vs 72,50 (17,70)] (p<0,1903); time maintained at VO2max (TMVO2max) [145,10 (72,50) s vs 64,20 (65,30) s] (p<0,1359), expressed values by median and interquartil amplitude. We conclude that the VO2 kinetics is similar between young and sedentary men and women, despite the biggest VO2 value demonstrated by men. The prescription value to the aerobic intervalled training do not have make off the proposed by literature for medium and high performance athletes. / O presente estudo teve como objetivo analisar e comparar a cinética de consumo de oxigênio entre gêneros em corrida no domínio severo. Participaram do estudo nove homens e nove mulheres (25,2 ± 2,6 anos; 22,1 ± 1,8 anos e, 77,3 ± 12,3 kg; 58,6 ± 9,6 kg, respectivamente). Foi realizado teste incremental em esteira rolante para determinação da velocidade associada ao VO2max (vVO2max), e corrida até a exaustão (Tlim) na vVO2max para determinar a cinética do VO2. O VO2max (3,29 ± 0,62 vs 1,90 ± 0,39) (p&#8804;0,0001), vVO2max (14,0 ± 2,0 vs 10,0 (3,0) km.h-1) (p<0,0108) e a amplitude (3,0 ± 0,7 vs 1,8 ± 0,4 L/min) (p<0,0003) (M±DP) foram significativamente maiores para os homens. Não foi detectada diferença estatística entre homens e mulheres para a constante tempo (&#964;) [35,8 (22,3) s vs 36,5 (6,6) s] (p<0,2973), Tlim [271,0 (118,0) vs 261,0 (73,0)] (p<0,6849), tempo para atingir o VO2max (TAVO2max) [142,3 (84,5) s vs 175,8 (24,6) s] (p<0,2973), %Tlim para TAVO2max [43,7 (24,4) vs 72,5 (17,7)] (p<0,1903); tempo mantido no VO2max (TMVO2max) [145,1 (72,5) s vs 64,2 (65,3) s] (p<0,1359), valores expressos pela mediana e amplitude interquartil. Concluímos que a resposta da cinética do VO2 é semelhante entre homens e mulheres jovens sedentários, apesar do maior valor de VO2max apresentado pelos homens.
