The Medial-Lateral Pedal Force Component Correlates with Q-Angle during Steady-State Cycling at Different Workloads and Cadences

Leg movement during cycling is constrained to the pedal/crank path and predominantly occurs in a sagittal plane. Medial-lateral force (FML) applied pedals considered as waste does not contribute pedaling. The aim of this study was examine changes FML across different cadences workloads, correlation with lateral knee (Q-angle). Twenty-two cyclists completed six trials at three workloads (2, 2.5 3 W/kg) (75, 85, 95 rpm). Forces were recorded from pedal mounted left side. Absolute normalized (to peak total force) compared conditions cross-correlation Q-angle calculated. significantly (p < 0.05) higher absolute cadence. There no significant difference cadences. decrease (~10 N) workloads. Statistically correlations found between (R = 0.70–0.77). results demonstrate link healthy pain-free stationary cycling. It has also been observed that smaller magnitude present when effectiveness increased.
