Associations Between Sleep Patterns and Performance Development Among Norwegian Chess Players
The sleep patterns of the chess players with positive performance development were different from the players with negative development – with higher amounts of deep sleep, less rapid eye movement (REM) sleep and lower respiration rate in the positive performancedevelopment group compared to the negative performance development group.

The findings fail to support the proposition that SWA reflects a need for sleep that accumulates at a rate depending on mental activity during prior wakefulness.
A new method for measuring daytime sleepiness: the Epworth sleepiness scale.

Reliability and validity studies of the Turkish version of the Epworth Sleepiness Scale
The Turkish version of the Epworth Sleepiness Scale (ESStr), a reliable and valid measure of daytime sleepiness, was applied to 194 healthy controls and 150 consecutive subjects attending the sleep centre with symptoms of sleep-disordered breathing to investigate the reliability and validity of the ESS in the Turkish language.
