Illustration of reconstructed method used to analyze the work-to-work transitions protocol kinetics. Letters M, H and S represent the model for Moderate, Heavy and Severe intensities, respectively; H’ and S’ represent model for Heavy and Severe kinetic curves when \({\dot{\text{V}}\text{O}}_{ 2}\) baseline was set at zero; H” and S” represent heavy and severe kinetic curves when time was aligned to zero; M + H” + S” represents the reconstructed curve with the sum of the three different intensities
