Despite the recognized influence of body mass on combat techniques, the relationship between body segment mass (BSM) and combat moves remains unexplored. This study aimed to examine the relationship between the striking arm mass (SAM), kicking leg mass (KLM), and body mass (BM) and the dynamic forces of direct punch (DP), palm strike (PS), elbow strike (ES), front kick (FK), and countermovement jump (CMJ) performance. Sixteen male military cadets (22.3 ± 1.8 years, 181.4 ± 7.0 cm, 82.1 ± 8.5 kg) performed combat techniques, with their performance measured by using a force plate and their body segment mass assessed by dual-energy X-ray absorptiometry. Spearman's correlation analysis, the Wilcoxon test, and Cohen's were applied. The results indicated the relationship between the KLM or BM and the FK impulse ( = 0.64, = 0.01; = 0.52, = 0.04, respectively) and CMJ impact force ( = 0.80, ≤ 0.01; = 0.70, ≤ 0.01, respectively). The FK peak and impact forces were moderately correlated with the CMJ jump height ( = 0.74, ≤ 0.01; = 0.77, ≤ 0.01). Moreover, the FK peak force was significantly higher than that for DP, PS, and ES ( ≤ 0.01, = 3.32; ≤ 0.01, = 1.6; and = 0.013, = 1.3, respectively). The highest relationship was found between the KLM and the FK impulse; however, the difference in variability explained by the KLM versus the body mass was only 12%. This suggests that knowledge of the BSM did not provide a significantly better estimate of the dynamic forces of the punches and FKs than the knowledge of the BM.
尽管体重对格斗技术的影响已得到公认，但身体节段质量（BSM）与格斗动作之间的关系仍未得到探索。本研究旨在探讨打击手臂质量（SAM）、踢腿质量（KLM）和体重（BM）与直拳（DP）、掌击（PS）、肘击（ES）、前踢（FK）和反向纵跳（CMJ）动作的动力之间的关系。16名男性军校学员（22.3±1.8岁，181.4±7.0厘米，82.1±8.5千克）进行格斗技术动作，其动作表现通过测力台测量，身体节段质量通过双能X射线吸收法评估。应用了斯皮尔曼相关性分析、威尔科克森检验和科恩效应量。结果表明，KLM或BM与FK冲量（分别为r = 0.64，p = 0.01；r = 0.52，p = 0.04）以及CMJ冲击力（分别为r = 0.80，p≤0.01；r = 0.70，p≤0.01）之间存在关系。FK峰值和冲击力与CMJ跳跃高度呈中等程度相关（分别为r = 0.74，p≤0.01；r = 0.77，p≤0.01）。此外，FK峰值力显著高于DP、PS和ES的峰值力（分别为p≤0.01，d = 3.32；p≤0.01，d = 1.6；p = 0.013，d = 1.3）。KLM与FK冲量之间的关系最为密切；然而，KLM相对于体重所解释的变异性差异仅为12%。这表明，与体重知识相比，BSM知识并不能显著更好地估计拳法和前踢动作的动力。
