We are currently looking for apparently healthy men and women. This study will consist of 3 visits to the Texas Tech University Department of Kinesiology and Sports Management, Sports Performance Lab. This study will be conducted under supervision from the principal investigator Dr. Yasuki Sekiguchi. The aim of this study is to evaluate the ability of the use of the device to detect blood volume. Estimated total time to complete is 5.0 hr (max), which include being provided set food and fluids on Visit 1, urine, blood, and orthostatic vitals collection on Visits 2 and 3. All participants who complete the study will receive $100. Measurements in this study include urine collection, height and weight, body water content, blood collection, blood pressure, respiration rate, self-selected skin color tone, and hydration measurement from the device. Blood collection may produce discomfort or minor bleeding and the possibility of bruising at the site of the needle puncture.
