BACKGROUND: This is an observational pilot study comparing kinematic variables of running between blind athletes and sighted athletes. Aim was to verify significant differences in the rhythmic pattern of fast running between male sighted and blind athletes, with similar anthropometric parameters and performance skills. METHODS: Four blind athletes (aged 25±4.25) classified in T11 blindness category and four sighted athletes (aged 24.2±1.29) were tested on 60 meters running, divided into two segments: the first 30 meters referred to the "acceleration phase," and the second 30 meters to the "maintenance phase" following the modified "Vittori model" to evaluate the running pace and stride length and comparing with those of sight athletes. RESULTS: Significant difference between groups on the number of steps in the maintenance phase, with the blinds showing a significant higher number of steps (P value=0.027), and a borderline significance over 60 meters between the two groups (P=0.063). CONCLUSIONS: Increased fatigue due to visual impairment or the need for more frequent ground contact and therefore proprioceptive input can have induced these adjustments. This strategy may be useful from both a safety and performance standpoint.
