O conteúdo é original e todas as fontes consultadas estão devidamente mencionadas na bibliografia ou outras listagens de fontes documentais, tal como todas as citações diretas ou indiretas têm devida indicação ao longo do trabalho segundo as normas académicas. O Candidato [assinatura] Lisboa, 27.10.19 RESUMO O trabalho é sobre uma imersão no oceano e em nós mesmos. A questão é: como podemos obter um efeito positivo por meio do oceano? O primeiro capítulo analisará os pensamentos antigos e contemporâneos do sublime; A figura do vórtice foi usada nas artes e na literatura para criar sensações sublimes, Immanuel Kant e Edmund Burke afirmaram que o sublime pode trazer um efeito positivo que será discutido. Uma sensação sublime diferente é a Liminalidade, que encontrei durante a Apnéia. Muitos artistas descrevem seu poder transformador, que será comparado à pesquisa médica científica. Mas a mensagem fundamental permanece: “A experiência sublime é fundamentalmente transformadora, sobre a relação entre desordem e ordem, e a ruptura das coordenadas estáveis de tempo e espaço. Algo se precipita e somos profundamente alterados.” (Morley, 2010, p.12) O segundo capítulo define Ambientes Imersivos em Artes e Apnéia. Após a experiência liminar comecei a treinar o desporto e aprendi a controlar minha mente e corpo de forma imersiva, o que trouxe à tona os conceitos: ponto do silêncio (preparação), jogo mental (submersão) e foco (volta a superfície).

  • POP Diving: the Big Blue
    POP Diving: The Big Blue BACKGROUND INFO and FACTS In the 60's and 70's, freediving world champions Jaques Mayol and Enzo Maiorca face one another in the blue, beating each other's records. Their performances leave medical experts of those times speechless, and bring freediving to the attention of the general public. It is Mayol, the Frenchman, who finally prevails on the Italian, becoming the first freediver to go beyond 100 meters of depth. And it is precisely around Mayol, considered the father of modern day freediving, that in 1987, movie director Luc Besson creates his first cult-movie, Le Grand Bleu. THE FILM The Blue is so vast and dream-like that it could envelop the collective unconscious of any living being, from man to bacteria. A strong surreal sense permeates the movie, from Mayol's (Jean- Marc Barr) dream to Enzo's mask (Maiorca is played by an outstanding Jean Reno), to the drinking scene in evening attire on the bottom of the pool. In full Besson-style, almost all the characters are caricatural, including Rosanna Arquette, who at times moves like a puppet, as well as the Italians, and the competition judges. At sea, though, things get serious, bodies hyperventilate, go down, come up, dance. They dance with dolphins. It is especially an ethereal Barr-Jaques Mayol who dances; in the movie, as in real life, he was the first to sense the physiological similarities between man and dolphin. Mayol lay the foundations for scientific exploration of the blood-shift phenomenon, and for modern day freediving.

  • Severe Hypoxemia During Apnea in Humans: Influence of Cardiovascular Responses
    From the Department of Physiology and Pharmacology Section of Environmental Physiology Karolinska Institutet Stockholm, Sweden Severe hypoxemia during apnea in humans: influence of cardiovascular responses by Peter Lindholm Stockholm 2002 ABSTRACT When a diving human holds his or her breath, the heart beat slows and the blood vessels constrict in large portions of the body. In diving mammals such as seals, similar responses effectively conserve oxygen for the brain, enabling them to dive very deep and to stay underwater for a long time. The principal aim of this thesis was to study the biological significance of bradycardia (a slowing of the heart rate) and vasoconstriction during apnea in exercising humans. The question was whether these cardiovascular mechanisms also in humans would temporarily “conserve” oxygen (i.e. temporarily reduce O2 uptake in muscles etc.) and thus protect the brain from a level of hypoxia that would otherwise cause unconsciousness in a breath-hold diver. A second aim was to determine the inter-individual variation among the human subjects in terms of the degree of bradycardia during apnea, in order to explore whether the intensity of these cardiovascular responses would make some individuals more fit to survive underwater swimming and apnea than others. Our results indeed showed inter-individual differences such that a high degree of bradycardia during apnea correlated significantly with higher levels (= better conservation) of arterial oxygen saturation. Thus, the subjects with the lowest heart rates during exercise and apnea had the best preserved saturation measured with earlobe pulse oximetry. Also, we found that the cardiovascular responses to apnea in exercising humans clearly delay the development of hypoxemia by reducing the rate of uptake from the main oxygen store, i.e.

    Journal of Human Kinetics volume 32/2012, 197-210 DOI:10.2478/v10078-012-0036-2197 Section - Aquatic Activities The Role of Training in the Development of Adaptive Mechanisms in Freedivers by Andrzej Ostrowski1, Marek Strzała1, Arkadiusz Stanula2, Mirosław Juszkiewicz1, Wanda Pilch3, Adam Maszczyk2 Freediving is a sport in which athletes aim to achieve the longest or the deepest breath-hold dive. Divers are at risk of gradually increasing hypoxia and hypercapnia due to a long time spent underwater and additionally of increasing hyperoxia while depth diving. Exceeding the limits of hypoxia endurance leads to loss of consciousness or even to death whithout immediate first aid. Often enhanced world records indicate the ability to shape specific to the discipline adaptive mechanisms of cardio-pulmonary system which are individually conditioned. During stay underwater heartbeats decelerating called bradycardia, increase in blood pressure, peripheral blood vessels narrowing and blood centralization in freediver’s organism. These mechanisms enhance blood oxygen management as well as transporting it first of all to essential for survival organs, i.e. brain and heart. These mechanisms are supported by spleen and adrenal glands hormonal reactions. Key words: freediving, breath-hold, training, adaptive mechanisms.

  • Physiology of Apnea with Emphasis on Dynamics Of

Acta Kinesiologica 11 (2017) Issue 1: 7-18 PHYSIOLOGY OF APNEA WITH EMPHASIS ON DYNAMICS OF 02 AND C02 IN THE ORGANISM AND SAFETY OF DIVE Mislav Lozovina and Ana Mrdeža University of Split, Faculty of Maritime Studies, Croatia Preliminary scientific communication Abstract Free diving (apnea) is the only purely anaerobic activity that man practices. During dives on his disposition remains a quantity of air and from it oxygen, which he has inside his lungs, bloodstream and tissues during the last breath before diving. During dives he exploits oxygen for metabolic processes and additional muscle work and its partial pressure is constantly falling while at the same time there is an increase in the partial pressure of carbon dioxide. When diving in a liquid medium (water), under the action of hydrostatic pressure, he is in a constant state of hypoxia and the gases in the body of a free dive are under pressure, or their partial pressures, by following certain rules of behavior of gases under pressure, regulating the duration of the apnea, and thus the safety of the dive. The aim of this paper is to become closely acquainted with all the facts about the physiological processes during the dives taking place in organic systems of free divers as to allow safe diving and avoid incidental situation, which has enabled the synergy of medical and technical sciences in explaining this complex and dangerous human activity. Key words: apnea, respiratory system, partial pressure of oxygen, partial pressure of carbon dioxide, dynamics of gases.
