Physiological and performance effects of glycerol hyperhydration and rehydration

Nutrition Reviews, 2009
Studies have shown that beverages containing glycerol can enhance and maintain hydration status and may improve endurance exercise performance by attenuating adverse physiological changes associated with dehydration. Improvements to performance include increased endurance time to exhaustion by up to 24%, or a 5% increase in power or work. However, some

Thermoregulation in hyperhydrated men during physical exercise

European Journal of Applied Physiology and Occupational Physiology, 1987
The influence of hyperhydration on thermoregulatory function was tested in 8 male volunteers. The subjects performed cycle exercise in the upright position at 52% Vo2max for 45 min in a thermoneutral (Ta = 23 degrees C) environment. The day after the control exercise the subjects were hyperhydrated with tap water (35 ml X kg-1 of body weight) and then ...

Salt + Glycerol-Induced Hyperhydration Enhances Fluid Retention More Than Salt- or Glycerol-Induced Hyperhydration

International Journal of Sport Nutrition and Exercise Metabolism, 2018
Hyperhydration has been demonstrated to improve work capacity and cardiovascular and thermoregulatory functions, enhance orthostatic tolerance, slow or neutralize bone demineralization, and decrease postdive bubble formation. Adding sodium or glycerol to a hyperhydration solution optimizes fluid retention.

Polyamines and hyperhydricity in micropropagated carnation plants

Plant Science, 2002
Changes in polyamine (PA) levels and patterns were studied in response to hyperhydricity in micropropagated carnation plants. Hyperhydric carnation leaves showed high peroxidase activity, low lignification and high malondialdehyde (MDA) content, suggesting oxidative damage.

Glycerol Use in Hyperhydration and Rehydration: Scientific Update

2012
Glycerol ingestion creates an osmotic drive that enhances fluid retention. The major practical applications for athletes are to either (i) hyperhydrate before exercise so that they have more fluid to be lost as sweat during subsequent performance, thereby delaying the progression of dehydration from becoming physiologically significant, or (ii) improve

Sodium-induced hyperhydration decreases urine output and improves fluid balance compared with glycerol- and water-induced hyperhydration

Applied Physiology, Nutrition, and Metabolism, 2015
Before 2010, which is the year the World Anti-Doping Agency banned its use, glycerol was commonly used by athletes for hyperhydration purposes. Through its effect on osmoreceptors, we believe that sodium could prove a viable alternative to glycerol as a hyperhydrating agent.

Prevention of gallium toxicity by hyperhydration in treatment of medulloblastoma

Pediatric Neurology, 1994
In vitro and in vivo studies have established gallium nitrate as an effective chemotherapeutic agent against human medulloblastoma. In vitro, gallium nitrate reduced cell proliferation and DNA synthesis of medulloblastoma Daoy. Gallium inhibits the availability of 59Fe to ribonucleotide reductase and has a direct effect on the enzyme itself.

Guidelines for Glycerol Use in Hyperhydration and Rehydration Associated with Exercise

Sports Medicine, 2010
Dehydration in athletes alters cardiovascular and thermoregulatory function and may inhibit endurance exercise capacity if fluid loss exceeds 2% of bodyweight (BW). If this level of dehydration cannot be prevented when starting from a state of euhydration, then athletes may create a state of hyperhydration by consuming extra fluid prior to exercise ...

[Ultrasonography in the hyperhydrated patient].

Giornale italiano di nefrologia : organo ufficiale della Societa italiana di nefrologia, 2013
The achievement of a normal hydration state is one of the major targets of hemodialysis. It is based on the estimation of ''dry weight'', which corresponds to the normal body fluid content. Even though the concept of dry weight in hemodialysis patients is clinically undisputed, it is not always easy to achieve in this population.
