Background: Several studies have investigated biomechanical deficits in jump landing; however, these studies are often performed in a laboratory with little distraction to the participant. Injury has been shown to occur during sport-specific distraction where the individual is cognitively loaded during motor performance. Purpose: The purpose of this study was to determine the effect of a cognitive task on jump-landing mechanics. Methods: A dual-task design was used to determine the effects a cognitive dual task on the tuck-jump assessment and peak vertical ground reaction force in 20 participants. There were three cognitive conditions (no cognitive task, easy cognitive task, and difficult cognitive task). Results: There were significant differences in overall tuck-jump score from baseline to easy cognitive task and baseline to difficult cognitive task. The cognitive dual task elicited statistically significant changes in overall tuck-jump score across the conditions with tuck-jump score increasing from 3.52 ± 1.64 baseline to 4.37 ± 1.25 with the easy cognitive task to 4.67 ± 1.24 with the difficult cognitive task. No significant differences were found in vGRF across the three conditions. Conclusion: The dual-task conditions affected jump-landing mechanics as measured by the tuck-jump score. Although there was a decrease in vGRF, no statistical significance was found over the three conditions.
