Anterior load carriage is common in occupational work and daily activities. Our primary purpose was to systematically review previous work concerning the biomechanics of walking with anterior load carriage. A secondary goal was to conduct a meta-analysis on common gait parameters relevant to front load carriage. An electronic database search yielded eight qualified articles. Meta-analyses were performed for four gait variables: stride length, heel contact velocity, required coefficient of friction, double support time. When possible, subgroup analyses by age were conducted. Results suggest that walking with front load carriage may shorten the stride length, particularly among young adults, but has small effects on the other three variables. Findings should be interpreted with caution given the limited number of studies included and small sample size per study. Future work investigating these four variables and others is needed to further our understanding of the impact of front load carriage on gait.
前载运在职业工作和日常活动中很常见。我们的主要目的是系统地回顾以前关于前载运行走的生物力学的研究。次要目标是对与前载运相关的常见步态参数进行荟萃分析。电子数据库搜索产生了八项合格的文章。对四个步态变量进行了荟萃分析：步长、脚跟接触速度、所需摩擦系数、双支撑时间。在可能的情况下，按年龄进行了亚组分析。结果表明，前载运行走可能会缩短步长，尤其是在年轻人中，但对其他三个变量的影响较小。鉴于所纳入的研究数量有限且每项研究的样本量较小，因此应谨慎解释研究结果。未来需要进一步研究这四个变量和其他变量，以加深我们对前载运对步态影响的理解。
