Assessment
Primary outcomes
hemodynamic responses, psychological responses, and salivary hormone were measured during simulated long working hours.
Key secondary outcomes
hemodynamic responses (systolic blood pressure, diastolic blood pressure, mean arterial pressure, stroke volume, heart rate, cardiac output, and total peripheral resistance), psychological responses (sleepiness, fatigue, stress, motivation, and depression), and salivary hormone (cortisol and C-reactive protein)
