Abstract This study focused on the salivary cortisol level and its relation to the two
components of flow (flow absorption and flow fluency) in tournament chess players
exposed to one of the skill-demand-level manipulations (underload, fit, and overload). The
aims of this study were to investigate how skill-demand-level manipulations affect cortisol
release and how flow and cortisol release are related in the context of an engaging task.
Specifically, the task involved fifty-seven tournament chess players playing chess against a
software in one of the experimental groups. We assessed flow after chess playing for
25 min via questionnaire and collected saliva before chess playing (T1), right after chess
playing (T2), and 10 min after T2 (T3). Our findings show that cortisol levels were
affected by the skill-demand-level manipulations. At T3, participants in the overload group
showed higher cortisol levels than participants in the fit and underload groups. There were
no differences in cortisol release between the experimental groups at T2. In addition, we
found the expected inverted U-shaped relation between cortisol release and flow absorption
at T2. A moderate level of cortisol was associated with a higher level of flow absorption. In
contrast, a higher level of cortisol was associated with a lower level of flow absorption.
Against our expectations, flow fluency was not related to cortisol release. We discuss
practical and theoretical implications of our results as well as potential for future research.
