Evaluation of erythrocyte deformability in subjects with sickle cell trait during a soccer game: effect of hydration ad libitum.

This study compared erythrocyte changes between a group of subjects with sickle cell trait (SCT) and controls (subjects without hemoglobinopathy) during a soccer game in two conditions: with and without hydration. Erythrocyte deformability of subjects was assessed by the coefficient of erythrocyte rigidity (Tk) which was calculated before and after football match. Our results showed [...]

Hydration biomarkers in free-living adults with different levels of habitual fluid consumption.

Background/objectives:In sedentary adults, hydration is mostly influenced by total fluid intake and not by sweat losses; moreover, low daily fluid intake is associated with adverse health outcomes. This study aimed to model the relation between total fluid intake and urinary hydration biomarkers.Subjects/methods:During 4 consecutive weekdays, 82 adults (age, 31.6±4.3 years; body mass index, 23.2±2.7 kg/m2; 52% [...]

Fluid and electrolyte balance during two different pre-season training sessions in elite rugby union players.

The purpose of this study was to compare fluid balance between a resistance and aerobic training session, in elite rugby players. It is hypothesised that resistance exercise will result in a higher prevalence of over-drinking whereas during the aerobic session under-drinking will be more prevalent.As with previous fluid balance studies, this was an observational study. [...]

Cost-effectiveness of recombinant human hyaluronidase-facilitated subcutaneous versus intravenous rehydration in children with mild to moderate dehydration.

OBJECTIVE: To evaluate the cost-effectiveness of recombinant human hyaluronidase-facilitated subcutaneous (rHFSC) fluid administration compared to intravenous (IV) fluid administration in children with mild to moderate dehydration in the emergency department (ED). METHODS: A decision analytic model was created based on the results of a controlled clinical trial that compared the administration of isotonic fluids via [...]

Dehydration upon admission is a risk factor for incomplete recovery of renal function in children with haemolytic uremic syndrome.

Haemolytic uremic syndrome (HUS) is the most common cause of acute renal failure and the second leading cause of chronic renal failure in children. The factors that affect incomplete renal function recovery prior to hospital admission are poorly understood. Objective: To analyse the risk factors that determine incomplete recovery of renal function prior to hospitalisation [...]

Effects of carbohydrate-hydration strategies on glucose metabolism, sprint performance and hydration during a soccer match simulation in recreational players.

OBJECTIVES: This study compared the effects of three carbohydrate-hydration strategies on blood glucose concentration, exercise performance and hydration status throughout simulated soccer match-play. DESIGN: A randomized, double-blind and cross-over study design was employed. METHODS: After familiarization, 14 recreational soccer players completed the soccer match simulation on three separate occasions. Participants consumed equal volumes of 9.6% [...]

Relation between urinary hydration biomarkers and total fluid intake in healthy adults.

Background/objectives: In sedentary adults, hydration is mostly influenced by total fluid intake and not by sweat losses; moreover, low daily fluid intake is associated with adverse health outcomes. This study aimed to model the relation between total fluid intake and urinary hydration biomarkers.Subjects/methods:During 4 consecutive weekdays, 82 adults (age, 31.6±4.3 years; body mass index, 23.2±2.7 kg/m(2); [...]

Effect of varying the concentrations of carbohydrate and milk protein in rehydration solutions ingested after exercise in the heat.

The present study investigated the relationship between the milk protein content of a rehydration solution and fluid balance after exercise-induced dehydration. On three occasions, eight healthy males were dehydrated to an identical degree of body mass loss (BML, approximately 1•8 %) by intermittent cycling in the heat, rehydrating with 150 % of their BML over [...]

Sports nutrition needs: before, during, and after exercise.

This article discusses how athletes should properly fuel their bodies before, during, and after exercise to maximize athletic performance. Emphasis is placed on hydration status and glycogen stores being maintained above deficits that negatively affect sport performance. Timing of nutrient intake is as important as composition. http://www.ncbi.nlm.nih.gov/pubmed/23668654
