Field events in track and field consist of throws (e.g., hammer, shot put, discus, javelin), vertical jumps (e.g., pole vault, high jump), and horizontal jumps (e.g., long jump, triple jump). Of the two horizontal jumps, triple jump is the most complex consisting of three phases: hop, step, and jump. Research has been conducted to examine limb motion and phasing distribution during triple jump performance; however, the effect of lateral deviation on triple jump performance in unknown. Purpose: The purpose of this study is 1) to determine the effect of lateral deviation on total triple jump performance within high school triple jumpers, and 2) to compare lateral deviation between training ages. Methods: High school triple jumpers (training age 2 ± 1.73 yrs, body height 169.33 ± 1.47 cm, body mass 62.75 ± 9.17 kg) performed four jumping trials at maximum effort. Lateral deviation of each step, i.e., hop, step, and jump, and the total jumping distance was measured. Results: There was a significant difference in effective and actual distance jumped p < 0.05. There was no significant interaction between effective and actual distance, p > 0.05. There was no significant difference in distance lost across phases: hop, step, and jump, p > 0.05. Conclusion: Lateral deviation did cause distance lost during triple jump performance. More investigation is needed to determine underlying causes of lateral deviation.
