Motivation (or lack thereof) is the foundation of any human action or inaction. However, its explanation and the exact identification of the activation mechanisms is still on the table, although psychology, but also other related sciences, have tried and are still trying to investigate this area of human existence. Physical activity is intrinsically linked to motivation, but it is not found at the same level, in all individuals, in any moment. In order to achieve performance, in general and in the field of physical education, in particular, any additional information regarding motivation is valuable. Equally beneficial for the physical education teacher can be a summary of the most important theories of motivation that are explained from different perspectives.
