The purpose of this study was to determine whether elite long jumpers make use of a visual control strategy during the final four strides of their approach. Analysis of existing film records revealed that all subjects adopted a visual control strategy at some point during their final strides. Data for the last four strides were insufficient to permit the actual point to be identified in most cases. A second study was undertaken to determine the location of this point and whether it is a function of the error accumulated during the preceding phase of the approach. The performances of 19 subjects were recorded over the last 8–10 strides of the approach. On average, the subjects adopted a visual control strategy on the 5th-last stride. The point at which this strategy was adopted was apparently unrelated to the error in the accuracy of striding up to that point.
