商业捕鱼是一项工作，其特点是长时间在不可预测的，动态的自然环境中工作，对肌肉骨骼系统的要求多变，需要力量，协调和耐力。该项目的重点是在量化的生物力学应力放在腰椎在商业捕蟹渔民的工作活动。背部应力的连续评估（CABS）方法被用来开发分布描述的时间量，每个船员在两个或三个人的螃蟹船员花费在不同水平的低背部应力。这项分析的结果，表示在时间加权直方图，显示出显着的跨和船员内的变化，在日常工作活动的压力措施。对于三名船员来说，船长在整个工作日中的压力水平相对较低，而大副在将蟹笼从水中拉到船上时执行高力（高达30公斤），动态用力，以及在早上和晚上装卸船时执行高负荷（20- 40公斤）。第三个人的船员经历静态尴尬的姿势（向前弯曲的姿势举行长达5分钟的时间），因为他的排序和包装的螃蟹。对于两个人的船员，结果表明，更均匀的分布之间的船员的高应力活动。本文讨论了人机工程学干预工作任务的优先顺序的分析结果的应用。
Commercial fishing is a job characterized by long hours in an unpredictable, dynamic natural environment and variable demands placed on the musculoskeletal system, requiring strength, coordination, and endurance. The focus of this project was in the quantification of the biomechanical stresses placed on the lumbar spine during the work activities of commercial crab fishermen. The continuous assessment of back stress (CABS) methodology was used to develop distributions describing the amount of time that each of the crew members on a two- or three-man crabbing crew spend at various levels of low back stress. The results of this analysis, expressed in terms of time-weighted histograms, show significant inter and intra-crewmember variability in the stress measures during regular daily work activities. For the three man crew, the captain has relatively low stress levels throughout the work day, while the mate performs high force (up to 30kg), dynamic exertions while pulling the crab pots from the water up into the boat and high loads (20–40kg) during the loading and unloading of the boat in the morning and evening, respectively. The third man of the crew experiences static awkward postures (forward flexed postures held for up to 5min at a time) as he sorts and packs the crabs. For the two-man crew, the results show a more even distribution of the high stress activities between the crewmembers. The application of the results of this analysis for prioritization of work tasks for ergonomic intervention is discussed.
