Outcome Measures

Primary Outcomes (6)

  • specific gravity of urine(SG)

    dehydration: \>= 1.020

    Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period

  • Osmolality(Urine)

    dehydration: \>= 700 mosm/kg

    Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period

  • Osmolality(Blood)

    dehydration: \>= 290 mosm/kg

    Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period

  • 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

  • sodium(blood)

    135\~145mEq/L

    Change from baseline outcome measure at dehydration and 1st and 2nd hour in recovery period

  • 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

Study Arms (3)

30min

EXPERIMENTAL

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.

Procedure: Different Fluid Ingestion Rate

60min

EXPERIMENTAL

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 60 min.

Procedure: Different Fluid Ingestion Rate

90min

EXPERIMENTAL

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 90 min.

Procedure: Different Fluid Ingestion Rate

Interventions

The participants ingested sports drink in a volume equivalent to 150% of BW loss, in 30 min, 60 min, or 90min.
