• Resumen

  • The aim of the present study was to analyse the movement of the buttock on the saddle based on pelvic motion and saddle contact pressure during a cycling specific graded exercise test. Nine female and ten male recreational cyclists took part in the study. Overall, both the saddle pressure distribution and the pelvic motion show that with increasing intensity/fatigue there is more movement between the buttock and the saddle to observe. In particular, pelvic movement in the frontal plane (rocking) should be considered for bike fitting interventions as well as for the design of saddles and seat pads at high load intensities/fatigue. Substantial pelvic movement can lead to critical shear forces between the buttock and saddle. These shear forces, combined with moisture development can therefore lead to a higher risk of seating discomfort and pain.
