Changes in exercise hyperpnea are more attributable to limb movement frequency than pedal loading

The significance of limb movement frequency in determining ventilation during exercise remains a contested topic in respiratory research. We used two sinusoidal exercise protocols on a cycle ergometer to separately assess the effects of limb movement frequency i.e. cadence (CP) and pedal load (LP) on ventilation. During the first test, cadence was altered sinusoidally while pedal load remained constant. In the second test, pedal load changed …
