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.

The purpose of this study was to compare the effects of four different treatments on the control of the amount and rate of foot pronation while running. The four treatments were the reverse 8-stirrup taping technique, the low-dye taping technique, prescribed rigid orthotic devices, and no support in the running shoe. Six intercollegiate cross-country runners were filmed from the rear while running on a treadmill, and the film data were analyzed. A two-way MANOVA indicated no significant overall treatment effect for the dependent variables. A one-way ANOVA indicated that the reverse 8-stirrup taping technique significantly reduced the amount of maximum pronation when compared to shoes-no support and low-dye taping techniques. The reverse 8-stirrup also had significantly fewer degrees of total rear foot movement when compared to the low-dye taping technique. No other significant comparisons were realized. It was concluded that the reverse 8-stirrup would be as effective a treatment for excessive pronation in runners as the prescribed rigid orthotic device.
