Biese: The Effect of a Dual-Task Paradigm on Jump Landing Performance (Under the direction of Darin Padua) Introduction: Dual-task (DT) paradigms use a cognitive test paired with functional movement. A jump-landing task and biomechanical evaluation using the Landing Error Scoring System (LESS) has not been used in a DT paradigm to date. Purpose: To determine if LESS scores and cognitive test variables would change during a jump-landing DT paradigm. Participants: 20 participants (age = 21.1 + 1.45 years, height = 176.5 + 9.9 cm, weight = 71.9 + 11.5 kg) were recreationally active college students. Procedures: Participants underwent 3 baseline cognitive tests. Then participants performed 12 jump-landing tasks, 9 jump-landings with a concurrent cognitive test and 3 jump-landing tasks with no concurrent cognitive test. Results: There was no change in LESS scores. Reaction time (RT) was significantly slower during DT. Conclusion: RT of a jump-landing task was negatively affected by a DT paradigm. These results demonstrate individuals sacrifice reaction time to create a safe jump-landing motor plan.
