Fig. 1

Individual example of the V̇O_2demand estimating (Panels A and B for male and female swimmers, respectively) and AOD profile during maximal 50, 100, and 200 m front crawl trails, with partial AOD increase being depicted at isotime 30 s for each swimming distance (Panel C and D for male and female swimmers, respectively). Obs.: In Panel A, the standard error of estimate (SEE) = 0.01 ml × kg⁻¹ × min⁻¹. In Panel B, the areas hachured and graded in grayscale correspond to AOD and V̇O_2Ac for each distance, and the line at the top of each area depicts V̇O_2Demad over time
