Patterns of wet suit diving in Korean women breath-hold divers
human breath-hold wet suit thermal protection
2009/7/15
Work shifts, diving pattern, diving lung volumes, and counterweights were studied in professional Korean women breath-hold divers wearing wet suits. One of the major differences, compared with their d...
Circulatory functions during immersion and breath-hold dives in humans
cardiac output dives humans
2009/7/15
An unusual circulatory state exists in humans immersed in water at or near 35 degrees C. This circulatory state is characterized by a persistent and elevated stroke index (SI) but heart rate (HR) chan...
Extremes in human breath hold, facial immersion bradycardia
human breath hold facial immersion bradycardia cardiac respiratory Immersion
2009/7/15
Although the average human response to apneic facial immersion in ice water is a reduction in heart rate from 70 to 45 beats/min, a small proportion of healthy subjects develop diving bradycardia to l...
Diving pattern of Tsushima male breath-hold divers (Katsugi)
human breath hold male Respiration
2009/7/14
The present study was undertaken to investigate the diving pattern, buoyancy-mass relationship, and some respiratory functions in professional male breath-hold divers in Tsushima Island, Japan. These ...
Carbon dioxide response and breath-hold times in underwater hockey players
CO2 carbon dioxide breath hold dive
2009/7/14
Competitive underwater hockey play demands frequent and prolonged breath-hold dives. To see whether participants were physiologically adapted to breath-hold diving we studied the ventilatory response ...
Breath-hold duration in man and the diving response induced by face immersion
cold exercise CO2 carbon dioxide Breath-hold face immersion
2009/7/9
The objective of this study in 5 selected volunteer subjects was to see whether the circulatory diving response which is elicited by breath holding and by cold water on the face would affect the durat...
Adaptations to deep breath-hold diving: respiratory and circulatory mechanics
nitrogen breath-hold respiratory circulatory
2009/7/9
Respiration and circulation in diving mammals are characterized by interrelated adaptations of structure, function, and behavior that are incompletely described and understood. This speculative survey...
A portable ECG recorder was used during breath-hold dives at sea by 3 elite divers to 65 and 45 m. ECG was also recorded during nonimmersed maximal breath holds in the divers and 8 control subjects. H...
Daily diving pattern of Korean and Japanese breath-hold divers (AMA)
cold breath hold gender
2009/7/8
Daily diving patterns and thoracic skin and sea-water temperatures were recorded during the entire work shift of Korean female unassisted (cachido) and Japanese male unassisted and partly assisted (fu...
Alveolar gas exchange during simulated breath-hold diving to 20 m
CO2 carbon dioxide pulmonary hyperbaric cardiac output breath-hold
2009/6/12
Alveolar gas exchange, as affected by changes in pulmonary blood flow, was studied in five subjects performing breath holds lasting 75 s at the surface and during compression to 20 m in a hyperbaric c...
Continuous pulse oximetry in the breath-hold diving women of Korea and Japan
Arterial oxygen saturation breath hold diving
2009/6/12
Arterial oxygen saturation during breath-hold diving has not previously been measured continuously. We devised a submersible, waterproof, backpack computer to continuously record heart rate, depth, an...
Supraventricular arrhythmias following breath-hold submersions in cold water
dry Supraventricular arrhythmias breath hold immersion cold water cardiac
2009/6/12
Twelve subjects undertook one submersion into water at 5 degrees C and two at 10 degrees C wearing either a wet or dry suit. During the submersions the subjects held their breath for as long as they c...
Circulating bubbles and breath-hold underwater fishing divers: a two-dimensional echocardiography and continuous wave Doppler study
decompression pulmonary breath-hold
2009/6/8
Since the 1960s,decompression illness after breath-hold diving has been widely debated. The aim of this study was to detect circulating bubbles after breath-hold diving in underwater fishing divers. W...
