Nowadays the sports activities are an increasingly important component of our life. In the new context of the automatic and cibernetic society, today the sport is no longer practiced exclusively for performance and competition, but is rather a leisure activity, practiced for pleasure and for physical needs.
This book highlights the operating mechanisms of the human body during effort, rewiewing the general theory about physical activity as well as being a guide for all athletes who need a theoretical explication of the sport phenomenon.
