Table 2.
Mean (± SD) values (with the 95% confidence intervals) for data used in calculation of MAOD.

| (95% C.I.) | (52.5, 54.7) | (42.1, 44.5) |
| total oxygen cost (mL·kg−1) | 219.8 ± 17.1 | 353.3 ± 23.8 |
| (95% C.I.) | (212.3, 227.3) | (342.9, 367.7) |
| traditional method, oxygen cost = oxygen demand × time | ||

| (95% C.I.) | (67.5, 74.5) | (39.7. 45.3) |
| traditional method, assumes oxygen demand is constant during exercise | ||
| excess oxygen cost (mL·kg−1) | 8.1 ± 4.0 | 37.1 ± 8.0 |
| (95% C.I.) | (6.3, 9.9) | (33.6, 40.6) |
| excess cost is assumed to equal excess oxygen uptake due to slow component | ||
| total oxygen cost (mL·kg−1) | 227.9 ± 17.8 | 390.4 ± 21.9 |
| (95% C.I.) | (220.1, 235.7) | (380.8, 400.0) |
| alternate method, oxygen cost = oxygen demand × time + excess cost | ||
| MAOD (mL·kg−1) | 79.1 ± 7.6 | 79.6 ± 8.3 |
| (95% C.I.) | (75.8, 82.4) | (76.0. 83.2) |
| alternate method, assumes oxygen demand increases during exercise |
Note: Values were calculated assuming that the oxygen demand increases across the bout of exhaustive severe intensity exercise (alternate method) and they were calculated using the assumption that oxygen demand is constant across the bout of exhaustive exercise (traditional method).
