目的：本研究旨在探討跆拳道運動員之功能性動作篩檢 (FMS) 綜合評分與各項評分結果，並分析其與平衡能力、爆發力之相關。方法：以10~17歲跆拳道運動員共36名 (男性25位、女性11位) 為研究對象，進行FMS檢測、靜態平衡能力評估 (COP)、下肢爆發力測驗 (蹲跳與反向跳躍)，以及收集相關研究數據進行分析。本研究統計方法採皮爾森積差相關 (Pearson Correlation ) 進行分析，統計顯著差異定為α= .05。結果：全體跆拳道運動員FMS總分平均分數為15.89±1.76分，66.66% (共24名) 運動員具有一項以上肢體不對稱現象。FMS總分及各項評分與靜態平衡能力無顯著相關 (p > .05)。在爆發力表現方面，FMS深蹲與蹲跳之向心發力率呈負相關 (p < .05)，旋轉穩定則與蹲跳高度、反向跳躍高度及修正式反應力指數(RSI)呈顯著正相關 (p < .05)，與蹲跳向心發力率呈顯著負相關 (p < .05)；此外，FMS總分與蹲跳向心發力率亦呈負相關 (p < .05)。結論：雖大多數跆拳道運動員FMS總分高於風險界定值 (14分)，但肢體不對稱比例偏高，特別是在旋轉穩定與伏地挺身項目得分偏低，顯示其動作控制與核心穩定性仍待加強，可能潛藏運動傷害風險。

Purpose: The purpose of this study was to investigate the composite and individual scores of the Functional Movement Screen (FMS) in taekwondo athletes, and to analyze their relationships with balance ability and lower-limb explosive power. Methods: A total of 36 taekwondo athletes aged 10 to 17 years (25 males and 11 females) participated in this study. Each subject underwent FMS testing, static balance assessment using center of pressure (COP) measures, and lower-limb explosive power tests including squat jump (SJ) and countermovement jump (CMJ). Relevant data were collected for statistical analysis. Pearson correlation analysis was employed to examine the relationships among variables, with the significance level set at α = .05. Results: The average total FMS score among all athletes was 15.89 ± 1.76, and 66.66% (24 athletes) exhibited at least one asymmetrical movement pattern. No significant correlations were found between total FMS scores or individual item scores and static balance ability (p > .05). Regarding explosive power performance, a significant negative correlation was found between the FMS deep squat score and the concentric rate of force development (RFD) during the squat jump (p < .05). The rotary stability score was significantly positively correlated with SJ height, CMJ height, and the modified reactive strength index (RSI) (p < .05), and negatively correlated with SJ concentric RFD (p < .05). In addition, the total FMS score also showed a significant negative correlation with SJ concentric RFD (p < .05). Conclusion: Although most taekwondo athletes had total FMS scores above the risk threshold of 14 points, a high proportion exhibited movement asymmetries, particularly with lower scores in rotary stability and trunk stability push-up, indicating deficiencies in motor control and core stability. These issues may potentially increase the risk of sports-related injuries and warrant further attention in training and screening.
