简要总结
Hydration is important to all individuals including occupational workers who complete physical activity in the heat. Current best practice guidelines suggest drinking a cup of water every 15-20 minutes during activity in a hot environment, but research shows this may not be ideal for best maintaining hydration. The goal of this study is to determine if larger, more frequent water boluses better maintain hydration than smaller, less frequent water boluses during moderate intensity physical activity in the heat.
