With the increase in the level of capabilities and interactions provided by the technological advancements, people are now expected to perform complex tasks which require both mental and physical resources. While subjective workload (or task load) assessments are generally used for mental or physical activities separately in the domains of effective learning and health promotion, the overall task load experience during a dual-task performance has not been focused in the previous research.


Approaching it from the perspective of dual-task, the subject of exergames is one of the other domains which require the mental and physical effort.

Exergames have been proposed as an innovative solution to increase physical activity by adding the layer of physical demand to the design of video games in addition to the mental demand they already require. However, the composition of these demands may turn a game into a complex activity for players. There is a lack of research on the effects of both mental and physical demands on gameplay experiences. Since the level of these demands may influence the overall experience and should be balanced to maximize outcomes, it is very important to assess the subjective workload for mental and physical demands to make exercising fun. To achieve this goal, in this study, I investigated the relationship between mental and physical load, and their effects on task load, enjoyment, flow, competence, effort and performance.
