N2 - This pilot study deals with the comparison of the basic kinetic and time variables of walk on treadmill and on overground. Three persons were investigated.Vertical plantar forces (VGF) and time characteristics were measured by the Pedar Mobile System (Novel GmbH, Munich, Germany). Probands made natural individual walk on flat and uphill land (9%) at speed 3, 4 and 5km/hour. For the laboratory research the treadmill Lode Katana Sport 30 (Groningen, NED) was used. For the overground research was used a pavement in the vicinity of the faculty. The speed during field research was checked with the help of cyclocomputer. Seven representative force and time parameters was selected: F1 – maximal vertical plantar force during absorption stage of stance (LR, MSt), F2 – the lowest vertical plantar force between both peaks, F3 – maximal vertical plantar force during propulsive stage of stance (TSt, PSw), Fm – average vertical plantar force for whole stance, t – total time of stance, t1 – time of absorption stage of stance, t2 – time of propulsive stage of stance. The probands walked for 15 sec and the last 10 sec was recorded. We evaluated three successive stances of left and right legs. Basic descriptive statistics was used (Mean, SD, percentage) and Effect of Size (Cohen d coefficient). For kinetic parameters (F1 , F3 ) were found out the tendency of increasing values in concordance of increasing speed of walk in the both tests conditions and for F2 was found the tendency of decreasing VGF for all the probands. For each of these parameters was found nearly all differences among field and laboratory significant. The values of F3 were always bigger in field and also values for F1 of two probands. Fm showed insignificant increase of VGR with increasing speeds for both conditions. The time of stance was reduced with increasing speed of walk in both environments. The differences of stances time between overground and treadmill tests were mostly significant. The shorter time of stance with increasing velocity of walk was caused on the first place of propulsive stage time reduction. The pilot research indicated probable kinetic and time differences between overground and treadmill walk and it shows the needs of follow-up survey of this topic.
