Colour graphics interpretation of AT and ${\mathbf{V}}^{\dot{}}{\mathbf{O}}_{\mathbf{2}}$/WR slope. This graphic shows the gradual change from high risk (red) to low risk (green) via an area of caution (yellow). It plots the AT and the $V^{\dot{}}{\mathrm{VO}}_2$ /WR slope. This minimizes the assumption that an AT of 10.9 ml.min⁻¹.kg⁻¹ is very different from an AT of 11.1 ml.min⁻¹.kg⁻¹ (see text). Reproduced with permission from Cortex Biophysik GmbH.
