Claim 4 of 5Not checkedCortisol increased only after the psychosocial stressor, not exercise, and higher cortisol reduced the children’s responsiveness to the salivary alpha-amylase changes and associated cognitive benefits.View evidenceHide evidence

Claim 5 of 5Not checkedOne researcher cautioned that the findings might suggest exercising before a task could help focus if the person is already prepared, but it may not help if they are already highly stressed, and it cannot promise a better test score.View evidenceHide evidence
