Optimizing Cold Water Immersion for Exercise-Induced Hyperthermia: A Meta-analysis
COOLING RECTAL TEMPERATURE EXERTIONAL HEAT ILLNESS SYSTEMATIC REVIEW
2015/4/20
Cold water immersion (CWI) provides rapid cooling in events of exertional heat stroke. Optimal procedures for CWI in the field are not well established. This meta-analysis aimed to provide structured ...
Body cooling in human males by cold-water immersion after vigorous exercise
human cold-water immersion vigorous exercise
2009/7/15
Five male subjects were immersed to neck level in a whole-body water calorimeter (water temperature 19 degrees C) on two occasions. One immersion was preceded by 30 min of exercise on a treadmill at 8...
Effect of hydrostatic pressure on plasma concentrations of norepinephrine during cold water immersion
human plasma norepinephrine thermal immersion
2009/7/14
Head-out immersion of humans in cold water concurrently stimulates low-pressure receptors and cutaneous cold receptors. In theory, the low-pressure receptors inhibit sympathetic nerve activity to the ...
Respiratory and cardiovascular responses to cold stress following repeated cold water immersion
cold CO2 carbon dioxide cardiac output air immersion Respiratory cardiovascular
2009/7/9
The effects of cold acclimation (CA) on the cardiorespiratory responses to cold air and water stress tests (CST) were studied in 7 males before and after a CA program of daily 90-min cold water (18 de...
Failure to reduce body water loss in cold-water immersion by glycerol ingestion
immersion glycerol ingestion water retention
2009/6/12
The efficacy of ingesting an aqueous glycerol solution to enhance body water retention during prolonged cold-water dives was evaluated. Nine Naval Special Warfare divers performed a 3-h dive in 13 deg...
Are beta-endorphins and thermoregulation during cold-water immersion related?
cold beta-endorphin thermoregulation immersion
2009/6/12
The purpose of this investigation was to determine the relationship between core temperature (Tre), tissue insulation (I), and beta-endorphins (beta-END) during immersion in cold water. To test this, ...
Effects of prolonged CO2 inhalation on shivering thermogenesis during cold-water immersion
CO2 carbon dioxide human air shivering immersion thermal cold
2009/6/12
We investigated the effect of prolonged hypercapnia on human thermoregulation during immersion of seven male subjects in a 15 degrees C water bath until their esophageal temperature dropped to 35 degr...
Physiologic and perceptual responses to hypercarbia during warm- and cold-water immersion
cold exercise CO2 carbon dioxide immersion hypercarbia Physiologic perceptual
2009/6/8
Thermoregulatory, respiratory, and perceptual responses to acute CO2 exposure during light exercise (75 W) were assessed in 12 U.S. Navy divers clad only in swim trunks while immersed to the neck in w...
Effects of prolonged CO2 inhalation on shivering thermogenesis during cold-water immersion
CO2 carbon dioxide human air shivering immersion thermal cold
2009/3/30
We investigated the effect of prolonged hypercapnia on human thermoregulation during immersion of seven male subjects in a 15 degrees C water bath until their esophageal temperature dropped to 35 degr...
Failure to reduce body water loss in cold-water immersion by glycerol ingestion
immersion glycerol ingestion water retention
2009/3/28
The efficacy of ingesting an aqueous glycerol solution to enhance body water retention during prolonged cold-water dives was evaluated. Nine Naval Special Warfare divers performed a 3-h dive in 13 deg...
Lack of diurnal effects on periodic exercise during prolonged cold water immersion
saturation exercise air Diurnal immersion cold water
2009/3/26
Diurnal effects on periodic exercise were examined in 8 male divers wearing passive thermal protection during whole body immersions in 5 degrees C water for periods of up to 6 h. Studies were done du...
