REHYDR8
Brief Summary:
It is well established that post-exercise rehydration with a carbohydrate-electrolyte solution is better when compared to plain water However most of the commercially available drinks today are high in carbohydrates and sodium with low potassium without other active ingredients The aim of the present study is to examine the impact of a higher electrolyte sports drink compared with traditional sports drinks and water on the time course and extent of rehydration after exercise-induced dehydration
Detailed Description:
Dehydration
Based on our previous work dehydration will be accomplished on the morning of testing via mild exercise and heat exposure to elicit a body weight loss of -2 The subjects will perform four bouts of 25-min low-intensity exercise and 5 min rest alternating cycling walking or till they reach -2 of body weight dehydration
Rehydration
Following a 20 min rest in thermo-comfortable environment a dehydrated baseline blood sample will be taken and subject will start the rehydration protocol
The volunteers will consume one of the four drinks below in a cross over balance mode During the first hour four equal doses will be consumed in15-min intervals at a total volume of 150 of their body weight loss
TrialsDrinks block randomization will be used to assign individual participants to each specific trialdrink using their ID number
Water
GoodSport
Gatorade
BodyArmor
Measurements
All measurements will be performed at one of the test rooms at our lab facility that boarders the room where participants can relax and wait out the end of the study day When certain measurements need to be performed they simply move from one room to the next Duration of taking blood and urine samples will take not more than 30-90 seconds each bioelectrical impedance will take a bit more time to ensure the body is in a stable rested state as a result measurement will be taken in 10 minutes finally perceptual data will take 30-60 seconds to be reported To allow to perform all measurements study days will take up to 7 hours Therefore there will be a separate space available that allows for self-study or watching TV that includes a chair and table to work on and a couch to relax
Blood samples 8 per trial maximal 12 minutes
A total of eight 10 mL blood samples will be collected on the euhydrated baseline dehydrated baseline and at 30 60 90 120 180 and 240 min of the rehydration period
All samples will be analyzed for glucose osmolality total plasma protein hematocrit hemoglobin for plasma volume changes sodium potassium and chloride
Urine samples 6 per trial maximal 9 minutes
Urine samples will be collected using 900 mL cups at euhydrated baseline dehydrated baseline and cumulative totals will be collected at 60 120 180 and 240 min of the rehydration period All samples will be analyzed for urine osmolality specific gravity volume sodium and potassium
Perceptual Data 6 per trial maximal 9 minutes
Thirst stomach fullness and taste assessed via a visual analog scale
