Benefits of exercise training on divergent thinking: The mediating role of ambiguity tolerance.

Exercise training has been proposed as a method for improving cognitive function. However, it is unknown whether chronic physical activity promotes divergent thinking and its underlying mechanism. Ambiguity tolerance has been considered relevant to divergent thinking. Therefore, this study sought to investigate whether individuals engaging in different types of exercise training differed in divergent thinking and to examine the mediating role of ambiguity tolerance underlying the training effect. The study was conducted in a sample of 492 university students who completed the unusual use task and the ambiguity tolerance questionnaire. The results revealed that individuals who underwent physical training proposed more creative ideas than non-physical training individuals did. Individuals engaging in multiple movement training scored higher in fluency, flexibility, and originality than their counterparts engaging in single movement training. Furthermore, ambiguity tolerance fully explained the difference in divergent thinking fluency between the physical and non-physical training groups. These findings provide preliminary evidence for the benefits of physical training on divergent thinking.
