The purpose of this study was to investigate selected kinematic variables of two classes of blind runners B-1 and B-3, in the 100-m dash. A total of 26 males served as subjects and were filmed in actual competition at the 1984 International Games for the Disabled. Filming was conducted at 150 frames per second with the camera positioned perpendicular to the plane of motion. Kinematic data extracted from the film included center of gravity, displacements, velocities, and selected joint angles. It was believed that the results of this study would be useful for (a) establishing some descriptive data of blind athletes in B-1 and B-3 classes, (b) understanding individual differences among blind runners of two different classifications, and (c) providing empirical data of the running patterns from which implications for the development of teaching/coaching methods might be gained.
