Fig 1. U-shaped and linear cost of transport (CoT) relationships at different gradients.

Fig 1

Filled and open symbols show the net and gross CoT, respectively. Circles, squares, and triangles show uphill, level, and downhill gradients, respectively. The mean gross ES, net ES, gross EOTS, and net EOTS are presented. Asterisks (*) indicate ‘gross > net’. Daggers, (†) indicate ‘gross < net’ at the level and downhill gradients. Hash mark (#) indicates ‘faster than the level and uphill gradients’. Section mark (§) indicates ‘faster than level gradient. The ES and EOTS markers were not put based on the correct CoT values, because the markers are likely to overlap with the CoT plots and regression lines. Data are mean ± SD.
