摘要

目的：本研究旨是研製可攜式踢擊測力器，可即時顯示數據之功能，代替傳統晉段測驗方法並探討不同體重、動作之踢擊力量之差異性，提供給跆拳道協會，作為未來晉段之參考。方法：本研究對象以中部地區道館國小男女生，取得一段資格學員，共計360人（男生180人，女生180人）進行實證分析，研究工具為自行研製可攜式踢擊測力器，其元件（荷重元、顯示器）均為澳洲及法國進口，且有原廠校驗合格證明書，為求更精準，做二種校驗並送TAF校驗通過，信賴水準為95%，證明本研究製作踢擊測力器，已有相當高準確度。結果：經踢擊實驗後，以單因子變異數分析(one-way ANOVA)及最小顯著差異法(Least Significant Difference, LSD)事後比較，結果顯示不同的性別及量級在下壓、旋踢及後旋踢等動作之踢擊力量，均有顯著差異；且不同的性別及量級方面發現，受試者體重愈重，其踢擊力量則愈大。結論：本研究製作測力器具有相當高準確度及穩定性，可代替傳統晉段測驗方法。經踢擊實驗得知體重愈重，踢擊力量愈大，也證實了資深教練們、大專跆拳道選手及研究者的看法。晉段測驗方法，若不區分體重測驗結果便有不科學，不公平之虞。建議跆拳道協會參考本研究結論，以科學儀器代替傳統，且區分性別及體重並期能酌參本研究製作測力器蒐集更多實驗數據進而建立客觀指標，使測驗過程與結果更趨完善。

This study developed a portable kick-strike strength measuring equipment which displayed the measured data immediately and could be used to replace the traditional rank promotion testing method. The effects of body weights and different movements on the kicksstrike strengths were also discussed and could provide for taekwondo association as a rank promotion test reference in the future. This study tested 360 students (180 males and 180 females) chosen from elementary schools in mid-Taiwan. All of these students had first-rank taekwondo certification. The testing data was then used to carry out the real diagnosis analysis. The test was done by using the portable kick-strike strength measuring equipment designed by the researcher of this project. The parts of the equipment (loading capacity sensor, display monitor, etc.) were imported from Australia and France with the original factory verification certificate. In order to get more precise data, two different kinds of verification had been done to pass the TAF calibrate. The faith standard is 95% which indicates that the kick-strike strength measuring equipment used in this study had high accuracy. After the kick-strike test, the single factor variation number analysis (one-way ANOVA) and LSD (Least Significant Difference) comparison were done for the testing data. The result showed that there were significant differences between the strengths of front and reverse turning and side kicks done by students with different gender and weight categories. It was obtained that heavier body weight would result in higher kick-strike strengths. The result indicated that the kick-strike strength measuring equipment designed in this study had high accuracy and stability and might be used to replace the traditional rank promotion test procedure. Through the kick-strike tests, it was obtained that heavier body weight resulted in higher kick-strike strength. This also confirmed that most senior coaches, taekwondo athletes and researchers' viewpoints. That the traditional rank promotion test procedure did not take the gender and body weight as a factor is unscientific and unfair. It was suggested that the taekwondo association should refer to the results of this study, taking gender and body as a factor and used scientific equipment to replace the traditional procedure in the rank promotion test. It is hoped that the kick-strike strength measuring equipment designed and manufactured in this study can be used to collect more testing data which can be used to establish the general rank promotion index and to make the rank promotion test more comprehensive.
