Which of the following statements is true for glycerol supplementation? Multiple Choice For each kilogram of body weight, athletes should consume 2 grams of glycerol combined with 10–15 milliliters of water Some studies indicate that glycerol-induced hyperhydration results in a lower heart rate and rectal temperature due to an increased blood volume, while others indicate no significant improvement over water-induced hyperhydration Glycerol-induced hyperhydration will increase osmotic pressure in the body fluids and thus, decrease plasma volume Glycerol supplementation is equally as effective for both cyclists and runners since it serves as a substrate for gluconeogenesis

Glycerol is a metabolite that can be synthesized in the body from glucose and can also be obtained as a food additive. From a biochemistry point of view, glycerol plays a major role with regard to the deprivation of glucose both in aerobic and anaerobic conditions. Athletes use glycerol to delay fluid loss and avoid dehydration during exercise. This metabolite is known to attract water so it stays in the body longer, increasing osmotic pressure and decreasing plasma volume. Glycerol is also used to lose weight and improve exercise performance. Moreover, it is important to note that it has been shown that intravenous injection of glycerol may damage red blood cells (hemolysis).
