该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。体育运动对运动员的身心都有要求。运动员满足这些要求的能力会影响他们的表现。食物、休息、饮料和其他因素都会影响运动员的成功。这项研究探讨了脱水对篮球运动员身心表现的影响。脱水是指体内的水分少于正常水平。本研究有2项试验。一项试验着眼于脱水对打篮球的影响。这个试验通过让球员在炎热的房间里锻炼，直到他身体的水分通过出汗失去所需的量来引起脱水。通过在锻炼前和锻炼期间称量身体来跟踪水分流失的量。另一项试验着眼于运动饮料对运动员表现的影响。在这个试验中，体内的水量保持正常。所有的测试都使用篮球训练来模拟篮球比赛，以测试球员的身体表现如何。采集血液样本以确保球员能够参加研究。在每次试验中，玩家吞下一种特殊的药丸，测量体内的温度

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Playing sports places demands upon the bodies and minds of athletes. Athletes' abilities to meet these demands affect how well they perform. Food, rest, drink, and other factors can affect an athletes' success. This study explores the effect of dehydration on how well a basketball player's body and mind performs. Dehydration is when the amount of water in the body is less than normal. This study has 2 trials. One trial looks at the affect of dehydration on playing basketball. This trial causes dehydration by having the player workout in a hot room until the desired amount of his body's water is lost through sweating. The amount of water-loss is tracked by weighing the body before and during the workout. The other trial looks at the effect of a sports drink on how well the player performs. The amount of water in the body stays normal for this trial. All trials use basketball drills to create a mock basketball game to test how well the player's body performs. A blood sample is taken to make sure that the player is able to be in the study. For each trial, the player swallows a special pill that measures the warmth inside the body
