Abstract
The presence of a dive response in humans when the face is submerged in water was studied. A lot of mammals have shown to exhibit a dive response known as the mammalian dive reflex. During this reflex bradycardia, a slowing of the heart rate, is shown. In this study, human subjects were put through various tests to determine if humans also exhibit bradycardia. Subject's heart rates were measured while breathing normally, while holding breath and while holding breath with face submerged in water. The results showed that there was a significant decrease in heart rate while submerged in water as compared to normal breathing or holding breath out of water. Many other studies have been done that agree with the results found in this study. However, this study would have had more significant results had other factors of the dive reflex been tested for.
Introduction
Mammals have shown to have a special reflex that allows them to dive to deep depths for long periods of......
