Summary: This study found that adding whey protein isolate to carbohydrate-electrolyte drinks can improve post-exercise hydration and endurance capacity compared to consuming the carbohydrate-electrolyte drink alone or in combination with casein protein.

Summary: This study examined the physiological values corresponding to voluntary drinking cessation after exercise, showing that urine specific gravity, osmolality, plasma osmolality, and thirst perception had returned to pre-exercise levels while rehydration relative to initial body mass was still incomplete.

Summary: A meta-analysis showed that ingesting hypotonic carbohydrate-electrolyte drinks during continuous exercise provides the greatest benefit to hydration. Hypotonic drinks were very likely superior to isotonic, and likely superior to hypertonic and water in terms of their effect on percent plasma volume (dPV) during exercise. Metabolic rate, ingestion rate, carbohydrate characteristics, and electrolyte concentration were found to be significant modifiers of dPV.

Summary: This study compared an ORS and SD for rehydration following exercise-induced dehydration and found that both ORS and SD were more effective in fluid retention than water placebo (W), with ORS showing better rehydration in the early recovery period.

Summary: First morning urine (FMU) assessment is a practical and convenient method to detect underhydration before competition/training and for the general public. Through a study on healthy women and men, it was found that FMU is significantly correlated with other variables such as osmolality, specific gravity, and color. FMU osmolality is the most useful indicator, with a threshold of 500 mOsm/kg for detecting underhydration.

Summary: This article discusses the uneven distribution of permeating ions on both sides of a permselective membrane, introducing a method for calculating Gibbs-Donnan factors and discussing special cases and transitivity of G-D factors for multi-ion solutions. The article also provides examples of calculating G-D factors for various solutions and an online tool for practical calculations.

Summary: In male endurance athletes, the oxidation of PHY reaches a plateau during prolonged exercise, with the peak oxidation occurring in the final 30 minutes. The ingestion of PHY also affects blood glucose levels during exercise.

Summary: The molecular mechanisms underlying the development of posthemorrhagic hydrocephalus (PHH) remain unclear, but elevated cerebrospinal fluid (CSF) osmolality is not the cause of PHH. The pathological CSF accumulation observed in these patients is instead attributed to other pathological alterations associated with the abnormal presence of blood within the CSF compartments following subarachnoid hemorrhage (SAH).

Summary: The study found a correlation between high urinary concentration of creatinine before surgery and postoperative elevation of plasma creatinine, with patients exceeding 11.3mmol/L of creatinine in their urine experiencing significantly greater increases in plasma creatinine at 6 hours and 1 day postoperatively. Patients with high urine creatinine failed to further concentrate their urine during the perioperative period, which increased the risk of postoperative elevation of plasma creatinine.

Summary: The electrolyte content makes the largest contribution to hydration properties of beverages for young adults at rest. The combination of carbohydrate or dipeptides can increase fluid retention, but the effect is quicker with sports drinks compared to dipeptide beverages.

Summary: This study observed that honey supplementation can lead to improved exercise performance compared to plain water and sports drink in hot conditions. Additionally, during the rehydration phase, participants who consumed honey and sports drinks had significantly higher levels of plasma glucose, insulin, and free fatty acids.

Summary: This study investigated sweat and fluid/carbohydrate intake responses in elite male professional soccer players training at different intensities and environments. The results showed that sweat rate and dehydration percentage were significantly influenced by exercise intensity and environmental conditions, while fluid intake was significantly associated with sweat rate. Carbohydrate intake varied between players due to individual differences.

Summary: The study compared the effectiveness of continuous flow enteral fluid therapy and intravenous fluid therapy in experimentally dehydrated horses. It was found that continuous flow enteral fluid therapy effectively restored imbalances and increased urine volume.

Summary: Fluid therapy is essential in veterinary care to improve hemodynamics, replace deficits, and maintain hydration. Consistency in terminology is important for precise communication in clinical and research settings, with this article providing a glossary of terms and common routes of fluid administration in small and large animal species.

Summary: This study characterized gastric and intestinal fluid from paediatric populations, finding large inter-individual variability in pH, buffer capacity, osmolality, and bile acid concentration. Further research is needed to develop simulated paediatric media and explore their impact on drug solubility and dissolution.
