Clinical Trial Summary

The purpose of the present study is to investigate the effect of different rate of fluid consumption on post-exercise rehydration.

Description:

The body water deficits equivalent to 2% body mass might impair performance. Due to high exercise intensity, thermal environment, or rule limitation, athletes often in dehydration status post-exercise. Thus, how to rehydrate effectively to prepare the next game is important. The participants arrived to the lab euhydrated and were dehydrated to 2% of body weight by running. After a rest, they will ingest sports drink in a volume equivalent to 150% of BW loss in 30 min, 60 min, or 90 min. Urine and blood sample will be collected to evaluate hydration status.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	specific gravity of urine(SG)	dehydration: >= 1.020	Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
Primary	Osmolality(Urine)	dehydration: >= 700 mosm/kg	Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
Primary	Osmolality(Blood)	dehydration: >= 290 mosm/kg	Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
Primary	Vasopressin	Vasopressin, also called antidiuretic hormone (ADH), arginine vasopressin (AVP) or argipressin, is a hormone synthesized as a peptide prohormone in neurons in the hypothalamus, and is converted to AVP. Increasing the water reabsorption and excretion of more concentrated urine.	Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
Primary	sodium(blood)	135~145mEq/L	Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
Primary	Body weight change	measure body weight at baseline, dehydration, 1st and 2nd hour in recovery period in kg	Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
