This study evaluates the differences between several categories in the 100m sprints (2014 IPC Athletics European Championship, Swansea). The analyzed parameters (according to Hay, 1986) are exposed in
the methods section.
A kinematic analysis of the 100m sprint was conducted (using the videos posted on the official web site) taking into consideration gender and disabilities: visual impairment (VI T11/12, T13); cerebral
palsy (CP T34, T35/36, T37/38); physical disability (PD T42, T43/44, T51, T52, T54).
Analyzed races: final (excluding athletes who did not enter de camera focus); 65 male races (9VI; 26CP; 30PD) and 40 female races (5VI; 24CP; 11PD).
Variables (mean and SD): official time [OT] (s), average race speed [Sp] (m/s), number of steps [SN], average frequency [Fq] (Hz), average step time [ST] (s) and average step amplitude [SA] (m).

In VI, those with lower grade of disability show lower space perception; and get better OT through greater Fq. Either in PC and in amputees, those with lower level of disability show greater Fq and
better OT. In wheelchair, male athletes keep high Fq, except for T51 (the category with greater disability). So, it can be observed that the greater the disability, the lower the Fq; and the lower the
disability, the greater the SA. Those who show better OT also show a greater Fq and SA.
In PC, OT improvement is achieved through greater SA (not through greater Fq). In PD, those who show a good OT are those who show a good balance between SA and Fq. In wheelchair, there is not enough
data to reach significant conclusions, so the results are only exposed for future research.
