Effects of Partial Sleep Deprivation on Cardiac Output During Cycling

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.
