The benefits that physical exercise confers on cardiovascular health are well
known, whereas the notion that physical exercise can also improve cognitive
performance has only recently begun to be explored and has thus far yielded only
controversial results. In the present study, we used a sample of young male
subjects to test the effects that a single bout of aerobic exercise has on
learning. Two tasks were run: the first was an orientation discrimination task
involving the primary visual cortex, and the second was a simple thumb abduction
motor task that relies on the primary motor cortex. Forty-four and forty
volunteers participated in the first and second experiments, respectively. We
found that a single bout of aerobic exercise can significantly facilitate
learning mechanisms within visual and motor domains and that these positive
effects can persist for at least 30?minutes following exercise. This finding
suggests that physical activity, at least of moderate intensity, might promote
brain plasticity. By combining physical activity-induced plasticity with specific
cognitive training-induced plasticity, we favour a gradual up-regulation of a
functional network due to a steady increase in synaptic strength, promoting
associative Hebbian-like plasticity.
