摘要
尽管身体质量对格斗技术的影响已得到公认,但身体部分质量(BSM)与格斗动作之间的关系仍未得到探讨。本研究旨在探讨打击臂质量(SAM)、踢腿质量(KLM)和身体质量(BM)与直拳(DP)、掌击(PS)、肘击(ES)、前踢(FK)和反运动跳跃(CMJ)表现的动态力之间的关系。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)表演了格斗技巧,他们的表现通过力板进行测量,身体部分质量通过双能 X 射线吸收测定法进行评估。研究采用了斯皮尔曼相关分析、Wilcoxon 检验和 Cohen's d。结果表明,KLM 或 BM 与 FK 冲力(分别为 r = 0.64,p = 0.01;r = 0.52,p = 0.04)和 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 峰值力和冲击力与 CMJ 跳高呈中度相关(r = 0.74,p ≤ 0.01;r = 0.77,p ≤ 0.01)。此外,FK的峰值力明显高于DP、PS和ES(分别为p≤0.01,d=3.32;p≤0.01,d=1.6;p=0.013,d=1.3)。发现 KLM 与 FK 冲力之间的关系最为密切;然而,KLM 与体重所解释的变异性差异仅为 12%。这表明,对 BSM 的了解并不比对 BM 的了解能更好地估计出拳和 FK 的动态力。
Associations between Body Segment Mass and Punch, Front Kick, or Countermovement Jump Performance in Military Cadets
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 d were applied. The results indicated the relationship between the KLM or BM and the FK impulse (r = 0.64, p = 0.01; r = 0.52, p = 0.04, respectively) and CMJ impact force (r = 0.80, p ≤ 0.01; r = 0.70, p ≤ 0.01, respectively). The FK peak and impact forces were moderately correlated with the CMJ jump height (r = 0.74, p ≤ 0.01; r = 0.77, p ≤ 0.01). Moreover, the FK peak force was significantly higher than that for DP, PS, and ES (p ≤ 0.01, d = 3.32; p ≤ 0.01, d = 1.6; and p = 0.013, d = 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.
