Sleeping Habits on Performance Following Sleep Deprivation

The goal of this randomized crossover clinical trial is to determine if habitual sleeping habits can predict endurance performance following a night of partial sleep deprivation in healthy untrained, recreationally trained, and trained cyclists (18-50 years, \~50% females). The main questions it aims to answer are: 1. Can habitual sleeping habits predict, or do different types of sleepers alter, performance outcomes following sleep deprivation? 2. Does sleep deprivation alter blood pressure, heart rate, or metabolic responses during a 20-minute time trial, and/or are these altered amongst different types of sleepers? * Participants will be asked to perform 4 performance tests (20-minute time trial), 2 for familiarization, and 2 testing visits (1 under normal sleep and 1 under partial sleep deprivation). * For 1 week prior to each testing visit, sleep will be tracked using an ActiGraph device. The investigators hypothesize that habitual early sleepers, poor sleepers, those with greater variability in sleep duration, and females will show the greatest impairments in performance following partial sleep deprivation.
