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在游泳时如何最好地控制呼吸。训练有素的游泳者首先先从鼻子上呼气，而不是在游泳时从嘴里呼气，即使他们的脸仍然在水下。从鼻子中呼气以避免长时间呼吸是一件重要的事情。在第一步中，我们旨在在水下呼气时测量鼻压。作者试图使用两个压力传感器来测量水下的鼻压。该研究的学科是健康的大学生，他们经历了长距离游泳。我们的特定目的是测量受试者水下呼气的鼻压。我们使用两个压力传感器将每个受试者的鼻压与各个深度的水压进行比较。在每种情况下，我们都发现鼻部压略高于相应的水压。
