Arm Description

The participants arrived to the trials euhydrated and were dehydrated to 2% of body weight (BW) by running. After a rest, they ingested sports drink in a volume equivalent to 150% of BW loss in 30 min.

Outcomes

Primary Outcome Measures

specific gravity of urine(SG)

dehydration: >= 1.020

Osmolality(Urine)

dehydration: >= 700 mosm/kg

Osmolality(Blood)

dehydration: >= 290 mosm/kg

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.

sodium(blood)

Body weight change

measure body weight at baseline, dehydration, 1st and 2nd hour in recovery period in kg

5. Study Description

Brief Summary

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

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.
