The torque- and power-pedalling rate relationship, parameters and determinants. The torque- and power-pedalling rate relationship is determined by an interaction of ‘force-based’ and ‘velocity & frequency-based’ factors. It should be noted that all determinants influence torque and power production at most pedalling rates experienced within sprint cycling; however, the relative importance of a given factor is pedalling rate dependent. Abbreviations: P_Max, maximum power; RPM_Max, maximum pedalling rate; RPM_Opt, optimum pedalling rate (i.e. optimal frequency); T_Max, maximum torque; T_Opt, optimum torque
