The ultimate aim of this study was to determine how swimmers could best control their breathing while swimming. Well-trained swimmers exhale first from their noses earlier than from their mouths while swimming even though their faces were still under the water. It is an important thing to exhale from the nose to avoid long time breath holding. For the first step we aimed to measure the nasal pressure while exhaling under water. The authors tried to use two pressure transducers to measure the nasal pressure under the water. Subjects of the study were healthy university students who had experienced long distance swimming. Our specific object was to measure the nasal pressure of the subject underwater exhalations. We used two pressure transducers to compare each subject's nasal pressure with the water pressure at various depths. In every case we found the nasal pressure to be slightly higher than the corresponding water pressure.

这项研究的最终目的是确定游泳者如何在游泳时最好地控制呼吸。训练有素的游泳者在游泳时首先从鼻子呼气，而不是从嘴呼气，即使他们的脸仍在水下。用鼻子呼气是很重要的，避免长时间屏气。第一步，我们的目标是测量水下呼气时的鼻压。作者尝试使用两个压力传感器来测量水下的鼻压。研究对象是经历过长距离游泳的健康大学生。我们的具体目标是测量受试者水下呼气的鼻压。我们使用两个压力传感器来比较每个受试者的鼻压与不同深度的水压。在每种情况下，我们都发现鼻压略高于相应的水压。
