| خلاصه مقاله | The effect of speed of walking on concurrent cognitive performance in healthy young people Background and Objective: Knowledge about cognitive performance during challenging walking conditions provides insight into the adaptability of central nervous system for controlling attentional demands of human gait. The aim of the present study was to assess the effects of walking speed on cognitive performance in young people during dual-task walking (DTW) conditions. Methods: Thirty young people (age: 27±4.42 years; 15 female and 15 male) participated in this study. They performed 6 walking trials on a treadmill, including walking at three paces (preferred, slower and faster) while subtracting 1’s or 3’s from a random three-digit number (simple and complex DTW, respectively). Each DTW task took 90 seconds to be done. As a reference for assessment of dual-task cost of cognitive performance, participants performed one seated 90-second trial of subtracting 1’s or 3’s from a random three-digit number. To calculate the cognitive score, first we calculated correct response rate (CRR) by multiplying the response rate per second in percent of correct responses for each of the cognitive tasks under seated and walking conditions. Then cognitive score for each dual-task walking trial was calculated by dividing the difference between CRR of each cognitive task when seated and walking to CRR of the same task when seated. Thus, A positive value indicates worse performance under dual-task conditions (ie, lower CRR), whereas a negative value indicates better performance under dual-task conditions (ie, higher CRR). We used a one-way analysis of variance for statistical analysis. Results: Our results showed that speed of walking had a significant effect on complex cognitive task (p<0.05), but not on simple cognitive score. Moreover, Bonferroni post-hoc results revealed that the mean of complex cognitive score was significantly lower When walking slowly compared to walking under preferred speed (p<0.05). Conclusion: In conclusion when people walk slower than their usual speed and perform a concurrent complex cognitive task, their cognitive performance declines significantly. This could be attributed to the higher physical controlling demand of slower walking compared to usual walking speed which may reduce the cognitive performance, regarding limited capacity of attention. |
