While we do not completely understand the complicated mechanism behind the link between cognitive function (academic performance) and physical fitness (exercise), there is emerging evidence that exercise results in increased Brain Derived Neurotrophic Factor (BDNF). Activity through the BDNF pathway can lead to neuronal growth and differentiation, axonal and dendritic growth, improved synaptic plasticity, and maintenance of existing neurons. This factor may one of the important links between physical exercise and physical changes to the brain leading to improved cognitive function!

This can not be a certain rule but good physical fitness may give rise to good blood circulation in the body especially to the central nervous system cells. So much oxygen to the brain results in much academic activity outcome.
In one word: BDNF. Paul Hafen summarized it and added an important review, here goes another one. I also suggest you search for Dr. John Ratey material.
There is a saying that says a healthy mind is in a healthy body, and this means that the functional apparatus of the human being must work with high efficiency in order for the human performance to be at a high level. A defect in any functional system (circulatory, respiratory, Nervous, bone, and muscular…) will lead to failure to obtain fitness Physical
It is one of the biological sciences that deals with the full functions of the various organs of the body while they are in full health and emphasizes the changes that occur to the whole body when the activity and work of these organs while performing their basic activities and investigating the cause and manner of performing those vital functions necessary to sustain the life of the organism. It studies the extent to which a person is healthy with the work of the body during exercise, and how sport and physical activity promote health and performance from the cell to the whole body. Understanding the impact of exercise includes studying specific changes in the muscular systems, cardiovascular, and nervous systems that lead to changes in functional ability and strength. As a result of endurance or strength training
In my opinion wich can be taken or not, We dealt with the circulatory system, muscles and respiratory a lot, but now we must touching on the nervous system, whether during rest or movement, and set standard levels for every effort that the average person or athlete makes to identify his physiological state that expresses the integration between the body with its physiology and the mind with its physiology. Recent studies in the sports field indicate the expression of brain signals and their relationship to performance, and then to physiological status and pulse rate.
