Although a pause in respiration during swallowing is a feature common to all mammals, inhibition usually occurs during expiration in adult humans and during inspiration in most other species. We tested the hypothesis that this difference is due, at least in part, to the position of the body while feeding. 2. The coordination of respiration and swallowing was studied in adult human subjects in two body positions; upright, which is typically human, and on hands and knees, which is similar to the feeding posture of most other animal species. 3. Our major finding was that the respiratory phase in which swallowing occurred was significantly related to posture. Swallows tended to occur late in the expiratory phase while feeding upright, but during early expiration while on all fours. 4. We speculate that the phase of respiration in which swallowing occurs changes with posture to compensate for the alterations in the mechanical properties of the upper body.

虽然吞咽时呼吸暂停是所有哺乳动物共有的特征，但在成年人类中，抑制通常发生在呼气时，而在大多数其他物种中则发生在吸气时。我们测试了这样一个假设，即这种差异至少部分是由于进食时身体的姿势所致。2. 在成年人类受试者中，研究了两种身体姿势下呼吸与吞咽的协调性；直立姿势，这是典型的人类姿势，以及手膝着地姿势，这类似于大多数其他动物物种的进食姿势。3. 我们的主要发现是，吞咽发生时的呼吸阶段与姿势显著相关。直立进食时，吞咽往往发生在呼气后期，但四肢着地时则发生在呼气早期。4. 我们推测，吞咽发生时的呼吸阶段会随着姿势的变化而改变，以补偿上半身机械特性的改变。
