The purpose of this study was to examine the effects of FOA cues on movement coordination of the lower extremity during a standing long jump. A modified vector coding analysis of hip/knee and ankle/knee coordination was used to evaluate the influence of FOA cues on coordination patterns and coordination variability. Results indicated no main effect of coordination patterns between FOA conditions for ankle/knee coordination F(1,19) = 0.43, p = 0.52 or coordination variability F(1,19) = 0.00, p = 0.98 and no main effect of hip/knee coordination patterns F(1,19) = 2.48, p = 0.13 or coordination variability F(1,19) = 5.0, p = 0.49. Participants did jump significantly further under and external FOA (2.27 ± .38m) than the internal FOA (2.16 ± .37m, p = 0.035). It is possible that manipulation of arm swing coordination or landing strategies are influencing the changes in jump distances between FOA conditions.
