PURPOSE To compare the reductions in evaporative heat loss from the skin (Esk) to internal heat loss (Hfluid) induced by ice slurry (ICE) ingestion relative to 37 °C fluid and the accompanying body temperature and local thermoeffector responses during exercise in warm, dry conditions (33.5 °C ± 1.4 °C; 23.7% ± 2.6% relative humidity [RH]). METHODS Nine men cycled at approximately 55% VO2peak for 75 min and ingested 3.2 mL · kg(-1) aliquots of 37 °C fluid or ICE after 15, 30, and 45 min of…

Does Cold Water or Ice Slurry Ingestion During Exercise Elicit a Net Body Cooling Effect in the Heat?

The cooling benefits of cold fluid/ice ingestion during exercise are likely disproportionately greater for athletes with physiological disruptions to sweating, such as those with a spinal cord injury or burn injuries, as their capacity for skin surface evaporative heat loss is much lower; however, more research is needed.

Effect of Ice Slurry Ingestion on Cardiovascular Drift and V˙O2max during Heat Stress

Although ice slurry ingestion attenuated CV drift more than fluid ingestion, it did not mitigate the decline in V˙O2max.

Ad libitum water consumption off-sets the thermal and cardiovascular strain exacerbated by dehydration during a 3-h simulated heatwave

4 °C or 20-°C ad libitum water ingestion prevented dehydration levels that exacerbate thermal/cardiovascular strain, despite blunted fluid intake with 4 ° C water.

• Cold water and ice slurry drinks are body-cooling methods that can be easily administered during exercise in the heat. However, core temperature is not reliably lowered compared to warmer drinks

The Effects of Crushed Ice Ingestion Prior to Steady State Exercise in the Heat.

Sweat loss, respiratory exchange ratio, heart rate and ratings of perceived exertion and thirst were similar between conditions, and precooling with crushed ice led to improved gross efficiency while cycling due to an increased heat storage capacity, which was the result of a lower core temperature.

Temperature of water ingested before exercise alters the onset of physiological heat loss responses.

This study sought to determine whether the temperature of water ingested before exercise alters the onset threshold and subsequent thermosensitivity of local vasomotor and sudomotor responses after

Effect of ice slushy ingestion and cold water immersion on thermoregulatory behavior

Both precooling treatments attenuated the thermal efferent signals until a specific body temperature threshold was reached, and increased Tre-Tsk gradient by CWI improved MPO while ICE reduced Tre but did not confer any ergogenic effect.

Temperature of Ingested Water during Exercise Does Not Affect Body Heat Storage.

The findings indicate that relative to cold water ingestion, consuming hot water does not provide a thermoregulatory advantage and both hot andcold water ingestion results in the same amount of heat stored during prolonged moderate-intensity exercise.

Ice slurry ingestion increases core temperature capacity and running time in the heat.

Compared with cold water, ice slurry ingestion lowered preexercise rectal temperature, increased submaximal endurance running time in the heat (+19% ± 6%), and allowed rectalTemperature to become higher at exhaustion.

Pre-cooling with ice slurry ingestion leads to similar run times to exhaustion in the heat as cold water immersion

As run times were similar between conditions, ice slurry ingestion may be a comparable form of pre-cooling to cold water immersion on submaximal running time in the heat.

Do greater rates of body heat storage precede the accelerated reduction of self-paced exercise intensity in the heat?

Reductions in self-paced exercise intensity in the heat are not mediated by early differences in S following the onset of exercise, simply due to transient differences in the rate of change in Tsk.

Temperature of ingested water and thermoregulation during moderate-intensity exercise.

Regardless of beverage temperature, water ingestion reduced the time-averaged changes in Tco and in heat storage during the second hour of exercise, but CL26 had no significant effect on forearm sweat rate or blood flow.

The effect of ice slushy ingestion and mouthwash on thermoregulation and endurance performance in the heat.

Although the benefits of cold-beverage consumption are more potent when there is ingestion, improved RPE, TC, and meaningful performance improvement with WASH supports an independent sensory effect of presenting a cold stimulus to the mouth.

Cold drink ingestion improves exercise endurance capacity in the heat.

Compared with a drink at 37 degrees C, the ingestion of a cold drink before and during exercise in the heat reduced physiological strain (reduced heat accumulation) during exercise, leading to an improved endurance capacity.

Sex differences in thermoeffector responses during exercise at fixed requirements for heat loss.

It is demonstrated that sex differences in sudomotor function are only evidenced beyond a certain requirement for heat loss, solely through differences in SGO, and the lower EHL and LSR in women are not paralleled by a lower SkBF response.

How should body heat storage be determined in humans: by thermometry or calorimetry?

The results demonstrated that although some estimates of thermometric heat storage matched the calorimetricS, other predictions underestimated it by up to 67% during passive heating.

The influence of serial feeding of drinks at different temperatures on thermoregulatory responses during cycling

The heat load and debt induced by periodic drinking resulted in similar body temperatures during low-intensity exercise in conditions of moderate heat stress due to appropriate thermoregulatory reflexes.
