“…The normalized work rate of 1.0 W/kg was calculated using The American College of Sports Medicine (ACSM) equations and used participant mass and a work rate of 75 RPM as inputs to the algorithm. As such, participants were instructed to maintain a cadence of 75 ± 2 RPM at all times during the 15 min bout of cycling [ 16 ]. All walking and cycling activities were completed in a climate-controlled indoor laboratory.…”

“…We recently demonstrated that performing single bouts of cycling at a pedaling cadence higher than the typical gait cadence increased self-selected gait velocity during level Sports 2024, 12, 159 2 of 10 over-ground walking [16]. We compared self-selected gait velocity immediately before and after a bout of cycling between three groups: one group that cycled at a comparable cadence to typical gait cadence of 55 revolutions per minute (RPM) but at an increased work rate of 1.5 Watts per kilogram (W/kg), one group that cycled at 75 RPM (a higher cadence than walking) at a normalized work rate of 1.0 W/kg, and a control group who cycled at a comparable cadence to typical gait cadence of 55 RPM at a normalized work rate of 1.0 W/kg.…”

We sought to investigate the lower-extremity biomechanics underlying increased gait velocity following high-cadence cycling. Ground reaction forces (GRF) and lower-extremity kinematics and kinetics were recorded as 15 healthy adults walked at a self-selected pace prior to and immediately following a 15 min bout of cycling at a cadence of 75 rotations per minute. Propulsive GRF and stance-phase peak dorsiflexion and knee extension angles increased, while peak plantarflexion and hip extension angles decreased. Swing-phase peak dorsiflexion, plantarflexion, knee flexion, and hip flexion angles increased, while peak knee extension angle decreased. Peak dorsiflexion, knee extension, and hip extension angular velocity also increased during swing. No changes in peak joint moments were observed; however, peak positive ankle, knee, and hip joint power generation increased following cycling. Completing high-cadence cycling improves gait velocity by increasing propulsive GRF; increasing joint angular velocity during the swing phase of gait for the ankle, knee, and hip; and increasing positive power production by the ankle, knee, and hip during the stance phase. Increased gait velocity post cycling exercise did not increase lower-extremity joint moments. Cycling may be a viable exercise-based modality for increasing gait velocity, especially in populations where gait ability or joint loading is of particular concern.

Background: Previous research has shown that increasing cycling cadence can result in improved post-cycling gait velocity. However, the specific threshold of cycling cadence required to bring about clinically meaningful changes in gait velocity remains unknown. This study aimed to determine the minimum increment in cycling cadence that would lead to a significant improvement in post-cycling gait velocity. Methods: A total of 42 young adults participated in our study and were randomly assigned to one of three groups: TEN, TWENTY, and THIRTY. Each group was assigned to cycle at a cadence at the corresponding percentage higher than the participant’s self-selected gait cadence. Each participant engaged in a 15-min cycling session at their respective assigned cycling cadence. Before and after cycling, participants completed a 10-meter walk test while spatiotemporal parameters of gait, ground reaction forces, lower extremity kinematics, and kinetics were recorded. Results: One-way ANOVA revealed no statistically significant changes in spatiotemporal, ground reaction force, kinematics, and kinetics variables pre- and post-cycling. However, there were both statistically significant (F(2,41) = 3.794, p = 0.031, η2 = 0.604) and clinically meaningful changes (0.07 m/s) in post-cycling gait velocity in the THIRTY group only. Conclusions: This suggests that a cycling cadence of 30% or higher is the minimum requirement to produce a clinically significant improvement in gait velocity.
