Cyclist Load-Velocity Relationship during leg-pedaling and how it is correlated with half squat

Abstract

This study examined how the force–velocity (F–V) profile obtained from maximal “on-bike” sprints corresponds to that derived from the half squat (HS), given the mechanical similarities between both tasks. Eight cyclists completed sprint tests with different gear ratios and an HS assessment using a linear position transducer. Both exercises showed highly linear F–V relationships (R² > 0.85) with nearly identical optimal power loads. Pedal linear velocity strongly correlated with HS mean propulsive velocity (r = 0.954; R² = 0.93), and maximal power outputs were also almost perfectly associated (r = 0.971; R² = 0.95). These findings support viewing short cycling sprints as a strength-oriented action suitable for velocity-based training and individualized load prescription.
