The study was undertaken to compare and analyze kinetic variables during downward foot-on according to the foothold heights under inter-rupted-visual information on 25-t cargo truck. Skilled adult male drivers (n=10) engaged in cargo truck driving over 1 year participated in the experiment. The results obtained from cinematographic and ground re-action force data during downward foot-on as follows; First, leg stiff-ness, peak vertical force (PVF) and loading rate showed significant dif-ference as an increase of foothold heights, that is, interrupted-visual in-formation showed greater impulse force than as was not. Second, vari-ables of center of pressure (COP) with interrupted-visual information did not showed difference, but anterior-posterior COP and COP area showed an increasing tendency as an increase of foothold heights. Third, dynamic posture stability index (overall, medial-lateral, anteri-or-posterior, and vertical) showed significant difference as an increase of foothold height, that is, interrupted-visual information showed lower index than as was not. Therefore it will be possible to control success-fully the leg stiffness, loading rate, and PVF when preparing an estimate for air phase time and impulse force through habitual cognition and confirmation at landing during downward foot-on from cargo truck. Identifying these potential differences may enable clinicians to assess type of injury and design exercise rehabilitation protocols specific.
