My age being what it is, universal acceptance of what we are now doing may not come within my lifetime; but it will come, because what we are doing is clearly established by simple laws of basic physics that cannot be denied forever. Arthur Jones In 2001, I started looking at exercise through renewed eyes, getting away from the traditional focus on basic physical abilities and muscle group-oriented training.
That is when my journey towards understanding humanmotion-applied Physics and Engineering began. I then realized that exercise and Engineering were very muchrelated, and a new perspective on Physical Activity and Sports Science was coming about. Lucas Leal This fascinating journey towards Exercise Mechanics started over a decade ago. The author will now go on to explain his vision on physical conditioning and will offer guidance to help professionals better apply their knowledge. LOOKING AT EXERCISE WITH NEW EYES When thinking about exercise, many people in our happen when you acquire deeper understanding, deeper field choose to disregard the evidence of Physics when knowledge. Even though it may not be easy to visualize considering exercise. They often also choose to ignore the forces, these are always present and they are responsible challenge of understanding the most complex engineering for any change our body experiences.
Exercise professionals of all: Human Engineering. Understanding these fields is a will be on their way to understanding Exercise Mechanics must if we want to get deeper into the least explored branch when they: of Biomechanics: Exercise Mechanics. It is essential that we - can visualize the applied forces and be able to manipulate achieve a sound knowledge of forces as applied, generated them, and tolerated by the body system. - know what constitutes an appropriate neuromuscular response to those forces, are able to assess the characteristics The reward to this effort will be worthwhile. A profound and effects of forces, comprehension of Exercise Mechanics will make it possible - understand a structures tolerance to those forces, for the exercise specialist to gain a whole new perspective. - know human structures and their force control mechanisms.
They will then see through renewed eyes, and this will enable them to analyze the invisible; that which is not seen Professionals will then be able to understand exercise but is, indeed, present in every movement, every method, beyond well-established myths. Their new eyes will give every piece of equipment. me better judgment to analyze the foundations of physical activity. The movie Matrix constitutes a good example of what does FORCES AND EXERCISE MECHANICS The human body doesnt know a thing about methods, or
