FIGURE 4.

Illustration of the calculation of maximal accumulated oxygen deficit (MAOD) for a subject, with a V̇O_2max of 65.5 ml kg⁻¹ min⁻¹. The subject ran at 118% of maximal aerobic speed (16.0 km h⁻¹ at 3° inclination) and with a theoretical O₂ cost of 76.1 ml kg⁻¹ min⁻¹. During the time to exhaustion of 157 s, the total accumulated O₂ cost (white and gray area combined) was calculated to equal 199.2 ml kg⁻¹. The accumulated VO₂ (gray area) during the 157 s was 116.2 ml kg⁻¹, giving a MAOD (white area) of 83.0 ml kg⁻¹.
