Abstract

Current law enforcement body drag tests may use dummy masses that are underweight compared to current population norms. This study aimed to determine differences in 74.84-kg and 90.72-kg body drag times when performed with a standard (pick up and stand with dummy prior to dragging), adapted (incorporation of time to lift dummy to standing), and preferred (drag with any technique) technique. Forty-three (24 males, 19 females) physically-active, healthy civilians (surrogate population for police recruits) completed drags over 9.75 m with 74.84-kg and 90.72-kg dummies using the three techniques previously stated. A 2 (mass) × 3 (technique) within-factorial ANOVA ( < 0.05), with Bonferroni post hoc, derived any dummy and technique differences. Thirty-five participants completed all the standard and adapted drags; all participants completed the preferred drag. There were significant main effects for dummy mass ( = 14.762, < 0.001) and technique ( = 23.272, < 0.001). Participants dragged the 74.84-kg dummy faster than the 90.72-kg dummy. The standard drag was completed faster than the adapted and preferred drags ( < 0.001). The adapted drag was completed faster than the preferred drag ( = 0.024). Even if a recruit is assessed with a lighter dummy, they need the capacity to perform heavier drags in the field. Activity-specific strength training during academy could aid this process. Though the time was slower, the adapted technique may offer information the standard technique does not as it includes the lifting portion of the drag. The preferred technique allowed all participants to complete the task, which could influence the drag techniques allowed if agencies increase testing dummy masses.

摘要

当前执法机构的身体拖拽测试可能使用的假人质量比当前人口标准体重轻。本研究旨在确定在使用标准技术(拖拽前捡起并扶起假人站立)、改良技术(加入扶起假人站立的时间)和偏好技术(用任何技术进行拖拽)对74.84千克和90.72千克的假人进行身体拖拽时,两者在时间上的差异。43名(24名男性,19名女性)身体活跃、健康的平民(警察新兵的替代人群)使用上述三种技术,对74.84千克和90.72千克的假人进行了9.75米的拖拽。采用2(质量)×3(技术)析因方差分析(<0.05),并进行Bonferroni事后检验,以得出假人和技术方面的差异。35名参与者完成了所有标准和改良拖拽;所有参与者完成了偏好拖拽。假人质量(=14.762,<0.001)和技术(=23.272,<0.001)有显著主效应。参与者拖拽74.84千克假人的速度比90.72千克假人快。标准拖拽完成速度比改良和偏好拖拽快(<0.001)。改良拖拽完成速度比偏好拖拽快(=0.024)。即使新兵用较轻的假人进行评估,他们在实际工作中也需要有能力进行更重的拖拽。在警校期间进行特定活动的力量训练可能有助于这一过程。虽然时间较慢,但改良技术可能会提供标准技术所没有的信息,因为它包括了拖拽的抬起部分。偏好技术使所有参与者都能完成任务,如果机构增加测试假人的质量,这可能会影响允许使用的拖拽技术。
