Gradient and rise of the time trial, blood lactate concentration and RPE values.
A. The gradient (thin line, in %) and the rise (fat line, in m) of the time-trial are plotted against distance (in km). The black arrows correspond to blood lactate concentration measures. For B and C, the white dots and dashed line correspond to the time-trial followed by active recovery, the black dots and solid line to the time-trial followed by passive recovery. The error bars correspond to SD. For a better readability, significant differences over time are not indicated. B. RPE given at the end of each km and at the end of the time-trial. C. Blood lactate concentration (in mmol.l-1) measured at different time points.
