Effect of Different Fluid Ingestion Rate on Post-exercise Rehydration
November 6, 2019 updated by: LIN, JIAN-YU, Kaohsiung Veterans General Hospital.
The purpose of the present study is to investigate the effect of different rate of fluid consumption on post-exercise rehydration.
Study Overview
Status
Unknown
Conditions
Intervention / Treatment
Detailed 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.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
specific gravity of urine(SG)
Time Frame: Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
|
dehydration: >= 1.020
|
Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
|
Osmolality(Urine)
Time Frame: Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
|
dehydration: >= 700 mosm/kg
|
Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period

Osmolality(Blood)
Time Frame: Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
|
dehydration: >= 290 mosm/kg
|
Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
|
Vasopressin
Time Frame: Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period
|
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.
