Abstract:When we think sports the other words that come in minds are fitness, competition, endurance, exercise and recreation; Physical Education and sports is very scientific. It has strong roots in science. Modern sports are not only demonstration of skills, strength and techniques but it is also shown scientific performance. It is equally powerful demonstration of science. From bicycle to tennis rackets and from high jump to long jump, it involves science. You may surprise to see sprinter who run 100 m in less than 10 sec. It is not only strength and speed that enable to run but it is also science that helps to run in such high speed. Why the shape of Helmet in cycling is having long tail? Why discus throwers spin the discus in air? There are thousand questions and all answers lies in science.
The purpose of the study was to illuminate various principles of physics and their implication in sports. The application of physics principles in sports know as biomechanics. The word biomechanics can be divided into two parts: the prefix bio- and the root word mechanics. The prefix bio- indicates that biomechanics has something to do with living or biological systems. The root word mechanics indicates that biomechanics has something to do with the analysis of forces and their effects. So it appears that biomechanics is the study of forces and their effects on living systems. This comes very close to the definition of biomechanics presented by Herbert Hatze in 1974: "Biomechanics is the study of the structure and function of biological systems by means of the methods of mechanics". The goals of sport and exercise biomechanics are performance improvement, technique improvement, equipment improvement, injury prevention and rehabilitation.
