Abstract:
The purpose of this research and development is to produce a model of physical exercise (nimrot) agility and acceleration on a football game for junior. In addition, research and development is conducted to obtain in-depth information on the development and application of models of physical exercise (nimrot) agility and acceleration on a football game for junior and determine the effectiveness, efficiency and appeal of athletes on the model created. Research and development using research methods development research & development (R & D) of the Borg and Gall. The subjects in this research and development is a junior soccer player many as 60 people. Instruments used in this research and development is a questionnaire, a questionnaire, as well as test instruments "Illinois test" used to collect the data level of agility, while the stages in research and development are, at this stage: (1) analysis of needs, (2) evaluation expert (initial product evaluation); (3) limited testing (small group testing); and (4) the main trial (field testing). Test the effectiveness of the model using the test "Illinois test" to determine the level of agility. Data were analyzed using "t-test" of data analysis obtained by the average value of pre-test 1612.03 and the average post-test 1403.13, the standard deviation of the pre-test 56.7 and post-test 54.3, the average pre-test and post-test 208.90 and standard 22:51 deviation value of 0.05 t 50.8 degree significant Since H0 is rejected. Test the effectiveness of the model using the test "30 meters acceleration test" to determine the level of acceleration. Data were analyzed using "t-test" of data analysis obtained by the average value of pre-test 450.10 and the average post-test 408.93, the standard deviation of the pre-test 10.38 and post-test 12.8, the average pre-test and post-test 49.167 and standard deviation 4.044. value of 0.05 t 66.599 degree significant Since H0 is rejected. Based on the information it can be said that the model of agility acceleration soccer game which is developed junior age effective and can increase agility and acceleration soccer player junior age.
