Each assessment was performed under 2 conditions: once with a dual task (serial subtraction) and once without a dual task, while jumping distance remained consistent across both conditions. ATTd and ITRd were measured using a 3-dimensional motion capture system from 0.25 seconds before initial contact (IC) to 0.75 seconds after IC. Additionally, dynamic knee flexion angle, knee valgus angle, maximal knee flexion moment, and foot angle at IC were measured.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      While performing a dual task during the side hop for distance, there was less ATTd during the flight phase and more ITRd during the landing phase (maximal difference [MD], 1.65 mm and 2.07\u00b0, respectively;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001), accompanied by a greater foot angle at IC (MD, 2.71\u00b0;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .002), resulting in a more pronounced toe landing.
