Sleep Deprivation
Conditions
Brief summary
Sleep deprivation has been found to impact exercise performance. The effects of both partial (several hours) and full (24+ hours) sleep deprivation on exercise performance has shown effects on rating of perceived exertion, rate of oxygen consumption, respiratory exchange ratio, and heart rate. A common practice with athletes is to perform regular physiological testing (submaximal and maximal) in order to assess their fitness and to determine training intensities. However, the effects of sleep deprivation on those same physiological test results has not been investigated Therefore, the purpose of this study is to investigate the effects of partial sleep deprivation on physiological test results.

| Breathing frequency | From baseline to completion, up to 31 days | Change from baseline in breathing frequency measured breath-by-breath using an online gas analyzer during submaximal and maximal incremental exercise |
| Minute ventilation | From baseline to completion, up to 31 days | Change from baseline in minute ventilation measured breath-by-breath using an online gas analyzer during submaximal and maximal incremental exercise |
| Blood lactate concentration | From baseline to completion, up to 31 days | Change from baseline in blood lactate concentration measured using capillary puncture during submaximal and maximal incremental exercise |
| Rating of perceived exertion | From baseline to completion, up to 31 days | Change from baseline in ratings of perceived exertion measured using a 15-point (6-20) scale during submaximal and maximal incremental exercise |
| Heart rate | From baseline to completion, up to 31 days | Change from baseline in heart rate measured using a heart rate monitor during submaximal and maximal incremental exercise |
