Study design.
This figure displays the enrollment and study completion process for participants.To maximize internal validity, the in-person laboratory visits were scheduled for the same time and day of the week, one week apart. BP, HR, and HRV measurements were taken following a 5-minute seated rest prior to each condition, and at 5- and 65-minutes post conditions. Room temperature was monitored and maintained at a temperature between 68–72°F (20–22.2°C) during all sessions. Participants were asked to wear comfortable clothes to both sessions to allow for ease of movement. They were also asked to refrain from nicotine and caffeine for six hours, eating for three hours, and intense exercise and alcohol consumption for 24 hours prior to scheduled visits.Participants completed self-selected desk work for approximately 50 minutes as a washout period between the 5- and 65-minute post condition rest and measurements. They were instructed to choose desk work that they did not perceive as stressful (e.g., reading, work on a personal laptop) and complete similar tasks during both sessions to standardize the washout period between conditions.
