Inertial Force in Sport and Fitness with Hula Hoop as an Example

Abstract

Survival issues are not only related to the competition against other ecological intruders for the same natural resources, but also to cope with many natural laws and physical principles which are modeling our behaviors and choices. Inertial force is very present in nature and evolution and knowing its modes or appearance would help us to use it for our benefit in our sport evolution. In sport practices inertial force is one of the resistance that people have to fight against for making aerobic exercises. General fitness are based partly in resistances to the inertial and other forces while mass muscle and strengths overcome them in opposition to these strong laws of nature. For instance, while playing hula hoop the inertial force can be used to build beautiful trick or performances as briefly described in this text. This rule of nature is present both to keep the symmetrical circle shape of the hula hoop and to preserve the movements/stillness in constant velocity or orientation.  This text is aiming to collect information to described the inertial force in different expressions in nature, to understand its presence in order to include the knowledge in sport trainings plan for better results.
