本研究旨在探討女子舉重選手急性脫水後口服四種不同組成的復水溶液，對液體存留率、胃腸道舒適度、血液值及無氧動力的影響。研究以12位女子舉重選手為對象，採交叉、平衡次序之設計；研究參與者於烤箱脫水2%體重後分別補充相當於1.5倍脫水量的低滲透壓電解質液（HES）、等滲透壓電解質液（IES）、運動飲料（SB）或純水（W），補充時間為脫水後立即、復水期之30、60及90分鐘。復水期間記錄胃腸舒適分數、測量體重（計算液體存留率），並採集靜脈血以測量血液滲透壓、葡萄糖及鈉、鉀與氯離子，於脫水前與復水期120分鐘時進行溫蓋特無氧動力測驗。研究結果顯示：補充HES、IES及SB於復水期90分鐘時的胃腸道舒適分數顯著低於補充W、而補充三種溶液於復水期60分鐘時的血糖值則顯著高於補充W，補充HES於復水期120分鐘時的血鉀值顯著高於補充SB及W；但補充四種溶液後之無氧動力與液體存留率並無顯著差異。研究結論：本研究證實舉重選手急性脫水後補充四種不同口服復水溶液並不會影響復水後之無氧動力，但補充含有醣類及電解質的溶液能有較佳的胃腸道舒適度，並血糖與血液電解質有維持的效果。

This study aimed to investigate the effects of supplementation of 4 rehydration solutions on fluid retention, gastro intestinal comfort, blood ionic profile, and anaerobic power in female weightlifters. In a counterbalanced, cross-over design study, 12 female weightlifters were asked to intake 4 different rehydration solutions after they lost 2% body weight through acute dehydration in sauna. The 4 types of rehydration solutions were hypoosmolar electrolyte solution (HES), iso-osmolar electrolyte solution (IES), sport beverage (SB), and water (W). The intake amount of rehydration solution was 1.5-fold to the lost of their body weight due to dehydration. Each rehydration solution was ingested immediately after dehydration, 30-min, 60-min, and 90-min of rehydration. The gastro intestinal comfort score and body weight were recorded during the rehydration period. Blood samples from each participant were collected to determine the levels of osmolarity, glucose, sodium, potassium and chloride before dehydration and during rehydration period. Wingate anaerobic test was also performed before dehydration and at 120-min of rehydration. The results indicated that gastro intestinal comfort score of the participants in HES, IES and SB supplements were significantly lower than in W supplementation at 90-min of rehydration. The blood glucose levels in subjects with HES, IES and SB treatments were significantly higher than in W treatment at 60-min. The blood potassium level in subjects with HES treatment was significantly higher than in SB and W treatments at 120-min. However, there were no significant differences on the anaerobic power and fluid retention percentage among the supplements. The major conclusion of this study is that supplementation of 4 different rehydration fluids after acute dehydration had no effects on the anaerobic power. Nevertheless, intake of the rehydration fluids containing carbohydrates and electrolytes resulted in superior scores of gastro intestinal comfort, and could maintain higher blood glucose and electrolyte concentrations.
