摘要

导言匕首是世界各地犯罪活动中常用的武器。伤害报告显示,上半身是最常见的攻击部位,刺伤比砍伤更致命。本研究的前两个目的是确定是否可以根据年龄和性别组来预测攻击类型和攻击位置。接下来的目标是比较不同性别和年龄组的袭击时间,并评估受试者特征对袭击时间的影响。方法共有 74 名受试者(男性:n = 40;女性:n = 34)参与了研究。受试者在 21 英尺(ft)的攻击过程中被录像,并参与后续问题和完成俯卧撑测试。将攻击时间(AT)、隐蔽位置、攻击类型和人口统计学信息与年龄组和性别进行了比较。结果 21 英尺攻击的平均 AT 为 2.40 ± 0.47 秒,最快为 1.75 秒。最常见的隐蔽位置、攻击类型和攻击目标的位置分别是右臀(62 人)、刺(62 人)和胸部(28 人)。在控制了俯卧撑能力(p <0.05)后,任何性别和年龄组的组合在 21 英尺高度的 AT 方面均无差异。俯卧撑能力是唯一能显著预测 21 英尺高度 AT 的因素(p < 0.05)。有 28 名受试者称,他们在 21 英尺攻击中故意避开了防弹背心。结论我们鼓励执法人员进行快速防御或进攻反应的训练,例如可以在 1.75 秒内完成的徒手对刀格斗或快速枪械技能。据预测,强壮的人完成 21 英尺攻击的速度更快。

The 21-foot principle: Effects of age and sex on knife attack characteristics

Introduction

Knives are commonly-used weapons in criminal activities and interpersonal assaults worldwide. Injury reports have identified the upper body as the most frequent location of knife injuries, and that stabbing attacks are more fatal than slashing attacks. The first two aims of the study explore whether the type of attack and attack location could be predicted from age and sex group. The following aims compared attack times between sex and age groups and evaluated the influence of subject characteristics on attack duration. The exploratory aim surveyed subjects on attack location during the scenario if the target was not wearing body armor.

Methods

A total of 74 subjects (male: n = 40; female: n = 34) participated. Subjects were video recorded during a 21-foot (ft) attack and participated in follow-up questions and completed a push-up test to determine physical strength. Attack time (AT), concealment location, attack type, and demographic information were correlated to age group and sex.

Results

Mean AT from 21 ft was 2.40 ± 0.47 s, with the fastest of 1.75 s. The most commonly observed concealment location, attack type, and attack location on the target included the right hip (n = 62), stab (n = 62), and the chest (n = 28), respectively. After controlling for push-up ability (p < 0.05), no differences were reported between any combination of sex and age group in AT from 21 ft. Push-up ability was the sole significant predictor of AT from 21 ft (p < 0.05). Twenty-eight subjects reported they purposely avoided the body armor vest during the 21 ft attack.

Conclusion

Law enforcement officers are encouraged to train for quick defensive or offensive responses, such as hand-to-knife combat or rapid firearm skills that can be performed in under 1.75 s. Stronger people were predicted to complete the 21 ft attack faster.
