The role of executive functions and physical fitness.
Cognitive-motor multitasking in everyday life, such as crossing the street while simultaneously using a mobile phone, consists of a number of action components with different demands. For example, while walking and standing place particularly high motor demands, smartphone use is associated with particularly high cognitive demands.
The results of a recent study suggest that the performance of the action components with high motor demands is mainly determined by the level of motor fitness, whereas the performance of the action components with high cognitive demands is mainly determined by the level of executive functions.
