Abstract

One of the numbers of matches held in karate is the word. The series of basic karate technique movements are combined into a beautiful movement performed single or team featuring the philosophy of karate, namely spirit and constancy. To be able to carry out the word properly, it needs to be supported by physical conditions, one of which is the power of the leg muscles. When carrying out the word power the limb muscles are needed to kick hard, jump high or perform sudden movements so as to create the perfect beauty of movement. In taking measurements of the power of the limb muscles, it is still equated to all karateka both kumite and kata. It is necessary to conduct research on the vertical jump, lewis formula and standing broad jump tests which are measuring the power of the limb muscles to find out the differences between the three types of tungki muscle power tests. Karateka Kata Junior (16-17 years old) who has a brown and black belt in Deli Serdang Regency with a total of 46 people, namely 25 men and 20 women, was sampled in this study. To test the differences between the three types of limb muscle power tests, homogeneity was first tested from the data and after the data were homogeneous, a paramtric test was carried out with a one-way anova test. Furthermore, the test was carried out with the Tukey HSD test to find out which sample group had a significant difference with the test criteria if the significance value (sig.) < 0.05 then there was a significant difference. The results of the one-way annova test analysis obtained values of F. 0.04 and sig. 0.996. With a significance level of 95%, it can be concluded that (sig.) > 0.05 then the average does not have a significant difference. So it can be concluded that there is no significant difference from the vertical jump, lewis formula and standing broad jump tests in measuring the power ability of the karateka limb muscles in junior. Furthermore, test Tukey HSD to find out the differences in each limb muscle power measuring instrument tested. From the results of the test carried out with the Tukey HSD test, it can be concluded that between vertical jump and lewis formulas, the sig value is obtained. (.996)>0.05 so it was concluded that there was no significant difference in the two limb muscle power measuring instruments. Testing of vertical jump and Standing Broad Jump increased the sig value. (.998)>0.05 so it was concluded that there was no significant difference in the two limb muscle power measuring instruments. Testing of Standing Broad Jump and Lewis Formulas yielded the sig value. (1,000)>0.05 so it was concluded that there was no significant difference in the two limb muscle power measuring instruments. Thus that all three tests have the same accuracy in measuring limb muscle power in junior word karateka.
