The development of the theoretical underpinnings for an exercise-cognition interaction, from inverted-U theories
of arousal and performance to psychoneuroendocrinological rationales, are examined. The extent to which research
has supported these rationales is also investigated and it is shown that there is little support for an inverted-U effect of exercise
on cognition. It would appear that exercise has a facilitative effect on choice reaction time but there is a lack of consistency
in the findings for other types of task. There is limited evidence that central executive tasks may be negatively affected
by heavy exercise. An integrated model drawing on physiological psychology, cognitive psychology and cognitive
neuroscience is proposed.
