Final answer:
The true statement relative to fluids taken during exercise is that cold drinks are absorbed faster than warm drinks. Factors like fluid temperature, volume, and carbohydrate concentration can impact how quickly and effectively water is absorbed during physical activity.
Step-by-step explanation:
Regarding the absorption of fluids during exercise, it is important to understand how different factors affect hydration. c. Cold drinks are absorbed faster than warm drinks is the statement that is true. Fluid absorption is influenced by the temperature of the liquid; cold fluids are more rapidly absorbed into the bloodstream compared to warm fluids. Additionally, water absorption is driven by the concentration gradient, meaning it moves from areas of higher concentration to areas of lower concentration.
Small volumes of fluids are also absorbed more quickly than large volumes. When small amounts of water are ingested, such as 200 ml, they tend to empty from the stomach and absorb into the body more quickly compared to larger volumes, like 600 ml. The type of sports drink can also influence how effectively water is absorbed. For instance, isotonic drinks have a similar concentration of dissolved content as the human body and can promote faster hydration.
Lastly, a glucose concentration greater than 10% does interfere with water absorption. High carbohydrate concentrations can slow gastric emptying and hence slow the absorption process. Therefore, it is not accurate to say that a glucose concentration greater than 10% does not interfere with the absorption of water.
