Introduction[edit | edit source]
It is essential to get an adequate amount of sleep every night for human health. This would equate to 6-8 hours of sleep. Accumulating this much daily sleep has restorative effects on the immune system, function of the endocrine system, and cognitive performance.
Sleep is also very important for athletes, as it plays an important role in physical, physiological, and cognitive performance. However, athletes are seen to obtain less rest due early rising times, and anxiety during heavy training periods and before competition.
Also, with the use of electronic devices, such as TVs, computers, tablets, and smartphones, can result in poor sleep quality, disturbed sleep, and a lower sleep duration.
Further information on the effect of electronic devices can be found on the Blue light and the Effect on Sleep page.
Effects of Sleep Loss[edit | edit source]
Sleep loss can have a negative effect on athletes' physical performance. It has been noted that total sleep deprivation has lead to a decrease in endurance performance. Partial Sleep Deprivation (PSD) has shown a reduced time to exhaustion. There are difering views and results obtained from studies regarding the effect of PSD. Some studies have shown there running to exhaustion was not affected by PSD. [1]
The loss of sleep has negative effects such as a heightened perceptual effort, and decreased emotional and cognitive function. The reduced cognitive function can be accompanied with a reduced psychomotor performance, via decreased vigilance, accuracy, and alertness. There can be a changed mood state, which can be involved int he reduced endurance performance. Rating of perceived exertion can also be skewed in the presence of PSD or TSD. [1]
Effects on Cardiorespiratory Health[edit | edit source]
Sleep deprivation, even for only one night, does have effects on cardiorespiratory health. Functions such as heart rate (HR), minute ventilation (VE), oxygen consumption (VO2), decreased within the duration of exercise to exhaustion. However, measurements remained unchanged with submaximal exercise to exhaustion. [1]
