Freediving is a sport in which athletes aim to achieve the longest or deepest breath-hold dive. Divers are at risk of gradually increasing hypoxia and hypercapnia due long time spent underwater additionally hyperoxia while depth diving. Exceeding limits endurance leads loss consciousness even death whithout immediate first aid. Often enhanced world records indicate ability shape specific discipline adaptive mechanisms cardio-pulmonary system individually conditioned. During stay heartbeats...
