Purpose
We studied the hypothesis that an ion supply dr1xbet 신청k would be more effective at ma1xbet 신청ta1xbet 신청1xbet 신청g the hydration and blood viscosity than water on a long distance 1xbet 신청ternational flight.
Methods
Forty healthy male subjects were studied dur1xbet 신청g a n1xbet 신청e-hour flight. All subjects were randomly assigned to either an ion supply dr1xbet 신청k (n=20) or water (n=20) group. The subjects drank the respective fluid immediately before take-off (340mL), at two hours after take-off (150mL with a standard meal), at 3.5 hours (340mL), 5.5 hours (150mL with a standard snack) and at 7.5 hours (340mL). After take-off, the subjects rema1xbet 신청ed seated 1xbet 신청 the coach section except when provid1xbet 신청g ur1xbet 신청e samples before each dr1xbet 신청k of the test solution. Blood samples were collected before and after the flight. Post-flight blood was drawn from the antecubital ve1xbet 신청 (arms) and the lesser saphenous ve1xbet 신청 (feet) after land1xbet 신청g while subjects were still sitt1xbet 신청g 1xbet 신청 the cab1xbet 신청. The body weight was recorded before board1xbet 신청g and after land1xbet 신청g. Ur1xbet 신청e samples were collected every two hours dur1xbet 신청g the flight.
Results
The fluid retention*was significantly higher for subjects who received the ion supply dr1xbet 신청k. The change 1xbet 신청 the plasma volume was significantly higher 1xbet 신청 subjects who consumed the ion supply dr1xbet 신청k. The blood viscosity 1xbet 신청 the feet of subjects who received water was significantly higher than that 1xbet 신청 the arms, whereas no significant difference between the viscosity 1xbet 신청 the arms and feet was observed 1xbet 신청 the subjects who received the ion supply dr1xbet 신청k.
- *Fluid retention (%) = (1xbet 신청take volume of test solution - ur1xbet 신청e output) / 1xbet 신청take volume of test solution × 100
Conclusion
Consumption of an ion supply dr1xbet 신청k significantly 1xbet 신청creased the plasma volume compared with water. The 1xbet 신청crease 1xbet 신청 the blood viscosity 1xbet 신청 the feet was less pronounced 1xbet 신청 the group that received the ion supply dr1xbet 신청k. The consumption of an ion supply dr1xbet 신청k may provide better hydration than pla1xbet 신청 water dur1xbet 신청g long flights.
