The torque- and power-pedalling rate relationship in the fatigue free and fatigued states (e.g. following 30 s maximal cycling). Because maximum force, maximum shortening velocity and relaxation rates are collectively impaired by fatigue; there is a reduction in maximum power (e.g. −56%) and a leftward-shift in the power-pedalling rate relationship. Accordingly, for a given ‘state of fatigue’, power production at high pedalling rates is compromised to a greater extent than at lower pedalling rates (e.g. −78% at 160 RPM vs. −56% at 120 RPM)
