Optimal Arousal Theory

Optimal Arousal Theory

The optimal arousal theory suggests that performance is maximized when an individual experiences a moderate level of arousal. This theory is closely tied to the Yerkes-Dodson law, which illustrates an inverted U-shaped relationship between arousal and performance. The law, formulated by psychologists Robert Yerkes and John Dodson, implies an ideal arousal level for optimal performance, and deviations from this level can lead to declines in effectiveness.

Summary

Esports players exhibit suboptimal sleep patterns, with better game performance linked to improved sleep quality, including more deep sleep and earlier sleep offset. This suggests a bidirectional relationship between performance and sleep in competitive gaming.

Area of Science:

Sports Science
Esports Medicine
Sleep Research

Background:

Esports athletes often report sleep disturbances impacting their well-being and performance.
Understanding the specific sleep characteristics and their relationship with game performance is crucial for this growing population.

Purpose of the Study:

To investigate the sleep characteristics of professional esports players.
To examine the effects of game performance on subsequent sleep patterns in esports athletes.

Main Methods:

Utilized a Somnofy sleep monitor over 56 days for objective sleep data collection.
Employed residual dynamic structural equation modeling (RDSEM) to analyze within- and between-person relationships.
Collected weekly self-reported game performance data from 27 Counterstrike players.

Main Results:

Esports players demonstrated sleep onset and offset times later than traditional athletes, with generally lower adherence to recommended guidelines.
Better game performance was associated with increased total sleep time and lower non-REM respiration rates (NREM RPM) at the between-person level.
Within-person analysis revealed that higher game performance predicted subsequent improvements in sleep, including more deep sleep, less light sleep, and earlier sleep offset and onset.

Conclusions:

Esports players' sleep patterns are often suboptimal, characterized by delayed sleep timing.
A positive correlation exists between game performance and sleep quality, suggesting that improved performance may lead to better sleep outcomes.
The findings highlight the intricate relationship between stress, performance, and sleep physiology in esports, warranting further investigation and targeted interventions.
