nfluence of Sex on Cognitive and Motor Dual-Task Performance Among Young Adults: A Cross-Sectional Study

Objective: To investigate the sex-related differences in single-task performance through mo-
tor torque, cognitive tasks and walking speed, and the combined dual-task costs (DTCs) con-
sidering both motor and cognitive performance in young adults.
Methods: Sixty-seven non-athletic subjects 37 females and 30 males were enrolled. The
study measured their knee extension muscle torque using an isokinetic strength dynamome-
ter and their walking speed using the one step app. these assessments were performed both
with and without a cognitive task, and the DTCs were calculated.
Results: The females exhibited significantly larger motor performance dual task effect
through (torque-DTC, speed-DTC) compared with males while exhibiting smaller cognitive
dual task effect with muscle torque and speed.
Conclusion: Deterioration in motor performance during muscle force production and speed
during dual tasks was large in females compared to males, whereas males experience a de-
cline in cognitive ability when performing dual tasks compared with females.
