The Effectiveness of Test for Speed and Strength Development for 12-14 Years Boys Judo Athletes: A Case Study of Binh Duong Province, Vietnam

Judo is an individual combat sport that requires high psychological, technical, tactical and physical factors, in which strength and speed play an important role. The aim of the study was selecting some tests for speed and strength development for 12-14 years boys Judo athletes, evaluating the effectiveness of these tests to develop speed strength for them. The study group consisted of 20 boys 12-14 years old Judo athletes in Binh Duong Province, Vietnam. The test for speed and strength development (collecting by previous research) was used in the study, including 5 tests: (1) Test 30m high start run (s); (2) Test long jump in place (cm); (3) Test prone push-up 15s (times); (4) Test Seoinage kick 20s (times); (5) Test knocking down Ippon Seoinage 30s (times). Test results based on the score tables were subjected to statistical calculations. An arithmetic mean, and Cv index were calculated for independent samples. The boys 12-14 years old Judo athletes who train 5 tests for speed and strength development exceed on the level statistically significant than the boys who practice current test. Comparing the results after the experiment between the two groups shows that the test system introduced by the study is superior to the current test system in terms of development rate (in each survey indicator, as well as in terms of average development rate).
