简要总结
It is well established that post-exercise rehydration with a carbohydrate-electrolyte solution is better when compared to plain water. However, most of the commercially available drinks today are high in carbohydrates and sodium with low potassium without other active ingredients. The aim of the present study is to examine the impact of a higher electrolyte sports drink compared with traditional sports drinks and water on the time course and extent of rehydration after exercise-induced dehydration
详细描述
Dehydration:
Based on our previous work, dehydration will be accomplished on the morning of testing via mild exercise and heat exposure to elicit a body weight loss of -2%. The subjects will perform four bouts of 25-min low-intensity exercise and 5 min rest (alternating cycling & walking) or till they reach -2% of body weight dehydration.
Rehydration:
Following a 20 min rest in thermo-comfortable environment a dehydrated baseline blood sample will be taken, and subject will start the rehydration protocol.
The volunteers will consume one of the four drinks below in a cross over balance mode. During the first hour four equal doses will be consumed in15-min intervals at a total volume of 150% of their body weight loss.
