Law enforcement officers (LEOs) use protective equipment to ensure safety. However, equipment carriage has been shown to impair movement quality and may increase the risk of musculoskeletal injury. Therefore, the objective of this study was to investigate the influence of equipment load carriage on functional movement as measured by the Functional Movement Screen (FMS). It was hypothesised that FMS scores would be negatively impacted by equipment carriage. A counterbalanced cross-over study was utilised and a convenience sample of 31 males and one female active-duty LEOs were included. Participants completed the FMS under two conditions: with and without equipment. Significant median decreases in the equipment condition were observed for hurdle step, shoulder mobility, and rotary stability ( < .01), and deep squat and dominant limb active straight leg raise (ASLR) ( < .05). The non-dominant limb ASLR and trunk stability push-up were similar between conditions ( > .05). Load carriage appears to impair functional movement among LEOs. Equipment carriage interferes with functional movement and neither of the two load carriage systems tested were superior to the other. When choosing between duty belt verses duty belt and outer carrier vest carriage, LEO preference, body type, and acclimation to a given carriage type should be considered.
执法人员使用防护装备来确保安全。然而,装备携带已被证明会降低运动质量,并可能增加肌肉骨骼损伤的风险。因此,本研究的目的是调查装备负荷对功能性运动的影响,功能性运动测试(FMS)用于测量功能性运动。假设装备携带会对 FMS 评分产生负面影响。采用平衡交叉研究,纳入了 31 名男性和 1 名女性现役执法人员的便利样本。参与者在两种情况下完成 FMS:携带装备和不携带装备。在装备条件下,明显观察到跨栏步、肩部灵活性和旋转稳定性显著降低(<0.01),深蹲和优势侧直腿抬高(ASLR)显著降低(<0.05)。非优势侧 ASLR 和躯干稳定性俯卧撑在两种条件下相似(>0.05)。装备携带似乎会降低执法人员的功能性运动。装备携带会干扰功能性运动,且两种负荷携带系统都没有比另一种更优越。在选择警服腰带和警服腰带加外穿战术背心之间时,执法人员的偏好、体型以及对特定携带类型的适应应被考虑。
