I just read "Head to Head With Rudi - Part II" and he was talking about "diaphragmatic equalization" and "air-recirculation" and "4-section breathing", does anybody know what that is?

Rudi: "...As for the specificities that pertain only to freediving, I have focused almost completely on improving and redefining the mammalian diving reflex response, and this has taken me down the road of negative-pressure diving and apnea, diaphragmatic equalization and air-recirculation, 4-section breathing..."
