Abstract:
Fitness which may be defined as the successful adaptation to the stressors of one’s life style is a desirable human condition and is based on a scientific and systematic training programme and those who are enamored of practice without science, are like a pilot who goes to the ship without rudder. As pointed out earlier and out of the latest scientific progress in the field of physical education and sports, it is a fact that strength is the most indispensable factor of physical prowess and the best way to develop strength is through an organized programme of weight training and all the empirical evidence available shows conclusively that through the judicious use of weight training, we effectively improve strength, muscular endurance and power, all of which are vital to the athlete. Based on the analysis and findings of the study, the hypothesis formulated earlier that there would be no difference in the effect of isometric and isotonic exercises on the performance of selected field events, is rejected in the case of putting the shot and running broad jump. With regard to the performance in putting the shot, both isotonic exercises and isometric exercises produced equal training effect in this event. All the two methods of strength training namely isometric, isotonic proved to be superior as compared to the control group in improving performance in running broad jump and putting the shot.
