明确的证据表明自主呼吸控制、腹内压和腰椎稳定性之间存在联系。然而，在手工材料处理过程中，人们对最佳呼吸控制知之甚少。目前还没有研究对最大负荷举重时的自然呼吸控制进行检验。14名健康受试者将一个装满货物的板条箱从地板抬到桌子上，同时收集呼吸流量数据。负重从体重的10%开始，以5%的增量增加到50%（如果耐受）。分析了最小、中等和最大负荷的数据。在最大耐受负荷的提升过程中，没有发生均匀一致的屏气。在所有三种负载中，在负载起飞前的激励频率最高，并且与准备起飞相比，负载起飞时的激励体积明显更高。屏住呼吸似乎与从地板到桌子的最大耐受负荷的提升无关。相关性声明：研究结果表明，在最大负荷提升过程中，可以识别出一致的自然呼吸控制模式，而不包括均匀的屏气。研究结果可能有助于创建最佳呼吸控制模型，这将最大限度地减少在手动材料处理任务中受伤的风险。
Clear evidence links voluntary breath control, intra-abdominal pressure and lumbar stability. However, little is known regarding optimal breath control during manual materials handling. No studies have examined natural breath control while lifting a maximal load. Fourteen healthy subjects lifted a loaded crate from the floor to a table while respiratory flow data were collected. The loads lifted began at 10% of body weight and increased up to 50% (if tolerated) by 5% increments. Data from the minimum, moderate and maximum loads were analysed. Uniform and consistent breath holding during lifting of a maximally tolerated load did not occur. Across all three loads, frequency of inspiration was highest immediately prior to lift-off and significantly higher inspired volume occurred at lift-off of the load compared with preparation for lifting. Holding the breath does not appear to be related to lifting of a maximally tolerated load from floor to table.Statement of Relevance: The findings demonstrate that consistent patterns of naturally occurring breath control during lifting of a maximal load can be identified and do not include uniform breath holding. The findings may assist in creating models for optimal breath control, which will minimise risk of injury during manual material handling tasks.
