THE EFFECT OF TWO WAYS OF WARM UP ON SOME OF THE FUNCTIONALITY AND PERFORMANCE IN SWIMMING EVENTS FOR AGES 14-16 YEARS

Sports activities required to prepare the body physically and psychologically, yet apart of the tenths of second set winner in the competition, as well as a good swimmer's performance is also affected by other variables including heredity factor and special training, which is a warm up, considered by many researchers as a critical factor for performance in training and competition alike. The warm-up can be defined in swimming and other physical sports as an initial preparation of internal body system to link physical activity on, before the main event in competitions, or by performing daily training program, with the aim of improving physical condition and thus achieving accomplishment. Generally, warming up is aimed to raising body temperature, increasing blood flow, respiratory rate, heart rate and the flexibility of the muscles involved in the working muscles, taking into account the stage of exhaustion, as well as to adapt the swimmers with water familiarity and with platforms, wall, jumping, and information about the things surrounding the swimmer. It is believed that all such information of warm-up established the swimmer to make a better performance during the competitions . The objective of this research is to evaluate the effect of two ways of warm up of some the functional capacities and the achievement in the 100 m freestyle event, the sample consisted of ten swimmers used to do different ways to warm up before swimming 100 m freestyle, they were divided into two groups, the first group (the control ) did the normal warm up (as a swimmer do in his daily training), the second group (experimental) used the warm up units prepared by the researcher, which included some varying proportions of maximum effort, The test was conducted of all swimmers and have been recorded all the search variables as a pretest , then they were tested after one week, as a post-test , where swimmers in their daily sessions trained usual program which prepared by their trainer , except that the experimental group was implementing a warm-up as organized by the researcher, then give the swimmers rest for 5 minutes, before testing 100 m freestyle, then the heart rate were measured after warming up and after completion of the test. The researcher concluded from the results that there is statistical significant between the warm-up methods used by two groups in the time of 100 m free style.
