Abstract

INTRODUCTION: This study investigated the effects of an eight-week pedal technique training program on functional threshold power (FTP), knee isokinetic strength, and bilateral strength symmetry in young cyclists. METHODS: Twenty-four male cyclists aged 15-17 years were assessed before and after an eight-week intervention. Anthropometric measurements, FTP, pedal analysis, and knee isokinetic strength at 60°/s, 180°/s, and 300°/s were evaluated. The training group performed pedal technique training twice per week, while the control group continued their regular training. RESULTS: No significant changes were observed in FTP, pedal asymmetry indices, or bilateral pedal power output. The training group showed significant improvements in knee extension and flexion peak torque at 60°/s and 180°/s, whereas no meaningful changes were found at 300°/s. Isokinetic results also indicated a reduction in pre-existing strength asymmetries. DISCUSSION: Pedal technique-focused training may improve lower-extremity isokinetic performance in young cyclists, particularly at moderate angular velocities, without significantly affecting FTP or overall pedal symmetry.
