: The accurate prediction of strength development relies on identifying the most appropriate measurement methods. This study compared diverse strength measurement techniques to assess their effectiveness in predicting strength development. Participants were taekwondo athletes competing at the red-black belt level or above. : Technical striking forces (palding, dollyeo chagi, dwit chagi, and yeop chagi) were measured using a Herman Digital Trainer fixed to a striking stand. Quadriceps and hamstring strength were assessed with a Lafayette force measuring device. Explosive leg strength was evaluated through a standing long jump test, normalized for leg length. The Pearson correlation coefficient was used to examine relationships between measurement methods. : The standing long jump test showed no significant correlation with other strength assessments. A moderate positive correlation was found between Herman digital trainer measurements and Lafayette digital hand-held dynamometer results. A high positive correlation (r = 0.736, < 0.001) emerged between hamstring strength and palding chagi technical strike force results. Technical strike kicks showed a significant positive correlation with each other and, also, a right foot-left foot correlation was observed. : It was concluded that the standing long jump test, which was shown as one of the explosive leg strength measurement methods in field studies as an alternative to laboratory tests, did not correlate with other strength tests; therefore, this test is weak and insufficient to predict strength skills in taekwondo. In addition, this study showed that the hamstring muscle was more predictive in the measurement of technical strength. In future studies, it might be more useful to measure hamstring muscle strength or technical kick strength instead of a standing long jump field test.
力量发展的准确预测依赖于确定最合适的测量方法。本研究比较了多种力量测量技术，以评估它们在预测力量发展方面的有效性。参与者为红黑带及以上水平的跆拳道运动员。使用固定在打击架上的赫尔曼数字训练器测量技术打击力量（前脚横踢、旋风踢、后踢和侧踢）。用拉斐特测力装置评估股四头肌和腘绳肌力量。通过立定跳远测试评估腿部爆发力，并根据腿长进行标准化。采用皮尔逊相关系数来检验测量方法之间的关系。立定跳远测试与其他力量评估之间无显著相关性。赫尔曼数字训练器测量结果与拉斐特数字手持测力计结果之间存在中等程度的正相关。腘绳肌力量与前脚横踢技术打击力量结果之间呈现高度正相关（r = 0.736，< 0.001）。技术打击踢法之间呈现显著正相关，并且还观察到左右脚之间的相关性。研究得出结论，立定跳远测试作为实地研究中作为实验室测试替代方法的腿部爆发力测量方法之一，与其他力量测试不相关；因此，该测试在预测跆拳道力量技能方面薄弱且不足。此外，本研究表明，在技术力量测量中，腘绳肌更具预测性。在未来的研究中，测量腘绳肌力量或技术踢腿力量可能比立定跳远实地测试更有用。
