Glucose and RPE Responses to Sleep Duration

Indianapolis, IN

The purpose of this study was to determine how college-aged females respond to exercise after one night of short (5-6 hours), regular (7-8 hours), or long sleep duration (9-10 hours). In this study, nine physically active females completed three trials which included a cycle ergometer workout at two percent of body weight as resistance. The independent variable was the amount of sleep and the dependent variables were blood lactate levels, blood glucose levels, heart rate, and ratings of perceived exertion. It was hypothesized that glucose and ratings of perceived exertion would be the greatest in the short sleep trial, the second greatest in the long sleep trial, and the least in the regular sleep trial. It was also hypothesized that lactate levels would be the least in the short sleep trials when compared to the long and regular sleep trials. Lastly it was hypothesized that heart rate would not change significantly between trials. Pilot data has been inconclusive and the data collection thus far has shown no definite trends supporting or rejecting the hypotheses. Data collection is still in process and complete data will be presented.
