Design outcomes

Primary

Measure	Time frame
Participants came to the laboratory on three separate visits. During the first visit, participants completed a questionnaire and provided informed consent. Age, height, weight, body fat percentage, BMI, BP, and HR were recorded. Exercise intensity was then calculated using the Karvonen method with age and HR. During the first, second, and third visits, participants completed an aerobic exercise protocol from 9:30-10:00 AM (AM trial), an aerobic exercise protocol from 5:30-6:00 PM (PM trial), and no exercise protocol (CON trial) was completed in random order. During each exercise, a HR monitor (Polar Unite, Polar Corporation, Kempele, Finland) was worn on the right wrist to obtain HR and a rating of perceived exertion (RPE) with a questionnaire. The three trials were separated by one week to eliminate the influence of the previous trial and minimize differences in participants' daily activities. Participants were asked to abstain from alcohol, caffeine, and binge drinking for 24 hours before the visit. After each visit, participants remained at home and wore a wrist-type BP during sleep monitor (HEM-9601T, Omron Healthcare Co., Ltd., Kyoto, Japan) on their left wrist, a sleep monitor (Actigraph wGT3X-BT (Ambulatory Monitoring, Inc., San Diego, CA) on their right wrist, and an HR monitor (WHS-1/RRD-1, Union Tool Co., Ltd., Tokyo, Japan) on their chest before going to sleep at night. Physiological parameters (BP, autonomic function, and sleep quality) were obtained before exercise and during nighttime sleep. All parameters were measured in a quiet room with constant room temperature and humidity (50%). Participants were asked to maintain a normal schedule that included the same bedtime and wake-up time after each exercise session to control for total sleep time. The study was conducted using a randomized crossover design.	—
