Effects of Partial Sleep Deprivation on Cardiac Output During Cycling
Sponsor: University of Guelph
Summary
The goal of this clinical trial is to determine if attenuations in cardiac output drive the blunted blood pressure response during cycling exercise following a night of partial sleep deprivation in young healthy adults (%50 females). The secondary outcome is to assess sex differences. The main questions it aims to answer are: * Do reductions in plasma volume drive reductions in cardiac output and therefore blood pressure during exercise following a night of partial sleep deprivation? * Do sex differences exist? Participants will: * Visit the lab after a night of normal sleep and a night of partial sleep deprivation. * Keep a daily diary of their sleep and food/beverage intake. * Perform maximal and submaximal exercise on a cycle ergometer.

Partial sleep deprivation
Participants will be asked to come to the lab for testing after a night of partial sleep deprivation. Participants will be asked to fall asleep at their habitual bedtime but wake up early (\~40% of normal sleep duration).
