Abstract
Those results cannot necessarily be consistent though a lot of relations between physical activity and mental
activity have been studied. In this text,we paid attention to the calculation task as a representative cognitive task,
and reviewed the previous studies about the effects of physical exercise on the performance of calculation task and
the clarification of those mechanisms by the method of brain function measurement.
These contents were as follows.
１. The effects of physical exercise on the performance of calculation task
1）The relationship between exercise intensity and calculation result
2）The relationship between exercise duration and calculation result
3）The relationship between fitness level and calculation result
２. The effects of exercise-induced brain awakening on mental activity
1）Reverse-U hypothesis
2）Excitation level of cerebrum
３. The neuron activity and brain hemodynamics with exercise and calculation task
1）Brain hemodynamics to the neuron activity with calculation task
2）Brain hemodynamics to the neuron activity with exercise
In the multipoint measurement simultaneously to a wide area including the prefrontal region by using optical
topography(NIRS topography system),the development of a further study about the influence of physical exercise
on a higher-order control of the brain and its mechanism is expected in the future.
