The aim of this paper was to: validate an integrated system (i.e., software application and hardware after calibration) to assess human’s horizontal intra-cyclic velocity with a mechanical speedo-meter. System validation was done for a set of land-based human locomotion techniques (from slow walk to maximal running) in four subjects and comparing it with a videometric system (i.e. APAS). There were no significant differences between pair wise data (speedo-meter versus APAS data) using student‘s t-test for both velocity coefficient of variation and maximal velocity. Linear regression models where very high for both the velocity coefficient of variation and maximal velocity. More than 80% of the Bland-Altman plots were within 1.96 standard-deviations.
