Outcome Measures

Primary Outcomes (2)

• User engagement and feasibility: Subjective and self-reported markers of hydration status

  Understand user engagement and feasibility of remotely collecting subjective and self-reported markers of hydration status

  At two identical 2-hour study sessions with at least one full day and a maximum of 6 days in between study sessions

• User engagement and feasibility: Markers of hydration using transdermal optical imaging (TOI)

  Understand user engagement and feasibility of remotely collecting markers of hydration using transdermal optical imaging (TOI)

  At two identical 2-hour study sessions with at least one full day and a maximum of 6 days in between study sessions

Secondary Outcomes (1)

• Understand the within subject variability of TOI features before and after acute fluid ingestion during remote data collection

  At two identical 2-hour study sessions with at least one full day and a maximum of 6 days in between study sessions

Other Outcomes (4)

• Self-reported measure of hydration status: Body mass

  Before and after acute fluid ingestion during remote data collection at two identical 2-hour study sessions with at least one full day and a maximum of 6 days in between study sessions

• Self-reported measure of hydration status: Urine color

  Before and after acute fluid ingestion during remote data collection at two identical 2-hour study sessions with at least one full day and a maximum of 6 days in between study sessions

• Self-reported measure of hydration status: Perceived thirst

  Before and after acute fluid ingestion during remote data collection at two identical 2-hour study sessions with at least one full day and a maximum of 6 days in between study sessions
