Iv fluids for athletes

Intravenous IV prehydration and rehydration has been proposed as an ergogenic aid to achieve euhydration more effectively and efficiently. Thirst is not an accurate indicator of how much fluid an athlete has lost. The ingestion of sodium during exercise may help with maintenance or restoration of plasma volume during exercise and recovery. Studies evaluating the benefits of IV hydration for repeated performances include a dehydration phase via exercise, a rehydration time, and a second exercise phase. This allows carbohydrate utilization and energy production to continue at high rates. There may be physiological benefits of decreased heart rate and norepinephrine in athletes rehydrated via IV route, but the clinical significance is not known. Open in a separate window References 1. At 15 minutes, there was no difference between IV and oral rehydration.

More rapid restoration of plasma volume was accomplished in the IV treatment group with no advantages over oral rehydration in physiological strain, heat tolerance, ratings of perceived effort, or thermal sensations.

Avoid carbonated drinks, which can cause GI distress and may decrease the volume of fluid consumed. There has been concern by parents, coaches, and athletes that sports drinks may contain too much sodium. Rehydration and Muscle Damage Muscle damage during exercise in the heat was assessed by myoglobin and creatine kinase.

Although anecdotal evidence does exist, at this time there are no high-level studies confirming that IV prehydration prevents dehydration or the onset of exercise-associated muscle cramps.

However, after 2 hours of exercise, the rectal temperature was 0. In these settings, there is a perceived benefit for the convenience and speed of fluid replacement. In these situations where time is limited, the speed of IV hydration may more rapidly correct deficits.
