The left and right prefrontal cortices are linked to networks that control approach and withdrawal motivation, respectively. The relationship between activity in the left and right prefrontal activity is used to assess brain states and specifically their link to motivational behaviours and tendencies. The most common measure used in this context is called the frontal alpha asymmetry (FAA), which compares alpha (8-13Hz) power at each region. Interestingly, research shows that FAA is influenced by aerobic exercise by increasing relative left prefrontal cortex activity. In turn this effect may be beneficial for individuals with mood disorders that are associated with abnormal motivational tendencies. However, it is unknown whether changes in FAA after exercise are due to cardiovascular demands of activity or simply the movement required for the exercise. Therefore, this study aimed to investigate the influence of aerobic exercise and 'no intensity' bilateral movement cycling on FAA in young healthy adults. Results showed aerobic exercise caused a significant increase in FAA scores 22-38minutes after exercise. However, movement did not lead to a significant change in FAA. This suggests there is an intensity required for physical activity to evoke a change in FAA.

Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate.
Alternating sets of exercise that work out different muscle groups and that also alternate between aerobic and anaerobic exercises, which, when combined together, offer an overall program to improve strength, stamina, balance, or functioning.
A cardiovascular exercise strategy with alternating short periods of intense anaerobic exercise with less-intense recovery periods.
