1. Introduction
A multitude of studies and researches conducted in recent years in different areas highlights, in addition to
many other issues, that a sedentary lifestyle causes obesity, poor body posture, a weak tone of the Core Muscles,
increased Body Mass Index and fat tissue, vertebral deformity, lack of mobility and flexibility, stiffness,
muscular atrophy, disorders of cardio-vascular function, anxiety, etc.
Physical inactivity, along with other factors (smoking, unbalanced diet), are constant elements of modern life,
inherently leading to a rapid increase in the number of people suffering from diabetes, cardiovascular disease
or obesity (Bocu & colab., 2001). However, these diseases can be largely prevented. The preventive
measures recommended by WHO are moderate physical activities for 30 minutes a day, quitting smocking
and healthy eating.
Confronting sedentary lifestyle has become a governmental problem in some countries. Thus, in some developed
countries a new lifestyle is promoted by providing the public facilities for encouraging the development of
fitness levels: creating safe routes for running, cycling, creating parks or green areas for leisure
