Key result
High cadence cycling (120 rpm) at submaximal intensities significantly increased oxygen uptake, work of breathing, and leg muscle blood flow compared to slower cadences.
Why the study?
The physiological consequences of freely chosen cadence during cycling remain poorly understood.
Does cycling cadence affect respiratory and hemodynamic responses in cyclists?
Comparison
Pedaling at 60, 90, and 120 rpm vs a freely chosen cadence (94.3 ± 6.9 rpm)
Design
Randomized crossover trial

May increase cardiorespiratory demands in submaximal cycling; hypothesis-generating for cadence optimization, needs prospective trials before practice change.

Does cycling cadence affect respiratory and hemodynamic responses in cyclists?
p-value: p=<0.05
High cadence cycling at submaximal intensities is metabolically inefficient and increases respiratory work and leg muscle blood flow compared to slower cadences.
Mitchell et al. (2019) conducted an RCT in Healthy cyclists (n=11). High cycling cadence (120 rpm) vs. Slower cadences (60, 90 rpm, and freely chosen) was evaluated on Oxygen uptake (V˙O2), electromyography of the diaphragm (EMGdi), work of breathing (Wb), and leg blood flow index (BFI) (p=<0.05). High cadence cycling (120 rpm) at submaximal intensities significantly increased oxygen uptake, work of breathing, and leg muscle blood flow compared to slower cadences.
