This will provide an improved reference for the relevant units of the competition rules. Due to technological advances, Taekwondo competitions use technology products to reduce subjectivity of a referee's decision. Since the implementation of electronic protectors, senior researchers, coaches, and the referees have often found many disadvantages in the scoring of competition when electronic protectors are used. For example, gently touching the electronic protective gear can cause induction; yet, in forceful kicking, electronic brace induction has not caused a gain in scores.
The electronic Taekwondo protective gear rack has been employed as the device of the study. The impact rack mining mechanical principle as fixed impact test. We found that old electronic protectors A-E (five electronic protective gear) were hit 250 times each. Electronic voltage protector average for A is 23.31, standard deviation 15.10; Electronic voltage protector average for B is 20.12, standard deviation 14.27; Electronic voltage protector average for C is 40.36, standard deviation 15.78; Electronic voltage protector average for D is 23.88, standard deviation 11.18; Electronic voltage protector average for E is 20.12, standard deviation 14.27.
To understand the new electronic protective gear and the used electronic protectors strike voltage difference between the case of the experiment, a single-factor analysis of variance (one- way ANOVA) is used. The result indicates significant differences (F = 90.193, p <.000). And, based on the Scheffe post hoc test, we found that the results of each old electronic voltage protector hitting tests vary considerably.
The experimental test results indicate that when this craft is hit, it shows stability and efficiency, it may further commercialization as lab ware. After this experiment, the electronic induction voltage was very unstable and each average reached significant differences. This is consistent with the results of this study. When the gear is used in the competition, we found that when gently touching or rubbing electronic protectors, the score is shown, however, kicking the electronic protectors has shown no scores. We suggest that before the competition electronic protective gear shall be carefully examined and protectors used for some years shall be replaced.
