Limitation
motor-cognitive dual-task training on EF
Limitations of the current study include its small sample size, which reduces the power to detect significant effects. Second, we only measured behavior. It will be important in future studies to investigate the dynamic changes in brain activity following motor-cognitive dual-task training. Although, short-term intervention is an effective way to explore the effect of dual-tasks on the EF of an individual, long-term intervention might be a better way to achieve continuous benefits. It is essential to conduct a large trial to examine the effect of motor-cognitive dual-task training on EF in a wide range of people.
