Since the beginning of the 21st century, multiple theories about science and other disciplines were found. The contemporary scientific world saw an array of discoveries and inventions. The theories are being challenged every day paving the way to new theories either challenging the earlier ones or supporting them and making them more advanced. Research is the systematic process of discovering new facts and verifying old facts, their sequences, inter-relationship, casusal explanations, and the natural laws which govern them. (Sharma, 1990) states that the main two objectives of the research are to make amendments to the existing knowledge and to search for new things in the related field. Thus, research takes us ahead of the current limits of knowledge. Research has played an important role in the development of sports. Sports persons are more competitive nowadays and always aim at the consistency of performance thus, the gap between winning and losing has eventually narrowed. Sports scientists and coaches study each and every aspect of the players to make them yield maximum performance. Developed countries have invented new means and methods on the basis of research. They have created an authentic system and environment for sports so as to achieve those targets which seemed almost impossible or difficult in the recent past for the human body and are still making diligent efforts for the betterment. On the basis of physical, emotional, and psychological aspects of the sportspersons, the researchers have collected such data so as to help in increasing the potential of the player in every sport. Sports performance depends on the complex combination of various factors such as physical, physiological, technical, tactical, psychological, and environmental. They supersede each other depending upon the nature of sports. It is often seen that though the athletes are imparted with the same training in view of all the above-stated factors, the performance level of each athlete varies distinctly with respect to each other. It depends basically on the differences in body structure and body composition of each athlete because the different physical activities and sports demand a different and particular type of body, size, and proportion.
