Program for Enchaining Legs Energy of 12-Year Old Soccer Players under Chiang Mai Municipality Schools

Abstract

       The objectives of this research were: (1) to create program for enhancing leg power of 12-year old soccer players under Chiang Mai municipality schools, and 2) to study the results of using the program for enhancing leg power of 12-year old soccer players under Chiang Mai municipality schools. Instrument used was the created program verifying the validity by experts. Get the content accuracy value = .67-1, get the confidence value 0.87.

       The target group was 20 soccer players under Chiang Mai municipality school and using the long distance ball passing test of Chuphong Chan-arun, Kanyala Palawiwat as well as measuring the leg muscle enhancing of 12-year old soccer players by using a leg dynamometer.  The results of the study showed that the experimental results of using program for enhancing leg power of 12-year old soccer players under Chiang Mai municipality schools for 12 weeks by 2 tests as follows: (1) the long distance ball passing before and after using, program for enchaining leg energy, it was found that the development of competency level of 11 soccer players were at a good level, 55 percent and the development of competency level of 9 soccer players were at a good level a fair level, 45 percent, the average distance of long distance ball passing of 20 soccer players before using program was at 15.34 meters and after using program was at 20.07 meters, the average distance difference was at 4.74, the development of competency was at a good level and had an average  of long distance ball passing before and after were at 1.99. (2) The test results of a leg dynamometer before and after using program for enhancing leg power showed that the average of leg dynamometer before using program was at 1.16 kg /weight and after using program was at 1.67 kg / weight.  The average of a leg dynamometer difference was at 0.51 kg / weight and the standard deviation before using the program was at 0.36 and after using the program was at 0.28, the standard deviation of a leg dynamometer was at 0.26 It can be concluded that after using the program for enhancing leg power of 12-year old soccer players by using long distance ball passing and the results of leg dynamometer higher than before have increased more than before using the program for enhancing leg power.
