The current literature suggests that load carriage can impact on a tactical officer's mobility, and that survival in the field may rely on the officer's mobility. The ability for humans to generate power and agility is critical for performance of the high-intensity movements required in the field of duty. The aims of this review were to critically examine the literature investigating the impacts of load carriage on measures of power and agility and to synthesize the findings. The authors completed a search of the literature using key search terms in four databases. After relevant studies were located using strict inclusion and exclusion criteria, the studies were critically appraised using the Downs and Black Checklist and relevant data were extracted and tabled. Fourteen studies were deemed relevant for this review, ranging in percentage quality scores from 42.85% to 71.43%. Outcome measures used in these studies to indicate levels of power and agility included short-distance sprints, vertical jumps, and agility runs, among others. Performance of both power and agility was shown to decrease when tactical load was added to the participants. This suggests that the increase in weight carried by tactical officers may put this population at risk of injury or fatality in the line of duty.
目前的文献表明，负重会影响战术军官的机动性，而在野外生存可能依赖于军官的机动性。人类产生力量和敏捷性的能力对于执行高强度动作至关重要，这些动作是在工作领域所需要的。本综述的目的是批判性地检查研究负重对力量和敏捷性测量影响的文献，并综合研究结果。作者使用四个数据库中的关键搜索词完成了文献搜索。使用严格的纳入和排除标准找到相关研究后，使用唐斯和布莱克清单对研究进行批判性评估，并提取和制表相关数据。有 14 项研究被认为与本综述相关，其质量评分百分比从 42.85%到 71.43%不等。这些研究中用于表示力量和敏捷性水平的结果测量指标包括短距离冲刺、垂直跳跃和敏捷性跑等。当向参与者增加战术负荷时，力量和敏捷性的表现都显示出下降。这表明，战术军官携带的重量增加可能使他们在执行任务时面临受伤或死亡的风险。
