Hello everyone

I'm currently writing an extended essay of 4000 words about the changes to the human body when undergoing freediving/freedivng training.

Does anybody know of interesting scientific research into freediving and the physiological effects it has on the body? I'm searching for data to back up points about bradycardia, contractions, hypoxia, hypercapnia and general body adaptations.

For example, research by Lindhold and Linnarson (2000) found that there was a significantly reduced uptake of Oxygen from the lungs during apnea in excersising men due to cardiovascular responses, and not just a fall in arterial oxygen saturation. This proves the fact that during apnea the body actively controls the amount of oxygen absorbed from the lungs, and consequently used by the muscles, so prolonging a dive.

This type of information really interests me, I have a brief understanding of general body adaptations in freediving but I like having the scientific proof that backs it up, and in some cases, explains why.

Does anyone know of any interesting experiments or sites or reasearch they have conducted themselves?

Thanks
