Arousal/Stress Effects of “Overwatch” eSports Game Competition in Collegiate Gamers

Abstract

To date, no physical response data are available for one of the most popular eSport games, Overwatch. The purpose of this investigation was to describe the stress signaling associated with competitive Overwatch play and to understand how acute hormonal responses may affect performance. Thirty-two male college-aged gamers (age: 21.3 6 2.7 years; estimated time played per week: 18 6 15 hours) completed the study. Subjects were randomly assigned to a 6-player team to compete in a tournament-style match. Salivary measures of cortisol and testosterone were collected immediately before (PRE) and after (POST) the first-round game, with the heart rate recorded continuously during the match. The mean characteristics were calculated for each variable and comparisons made by the skill level. Significance was defined as p # 0.05. There were no differences in measures of salivary cortisol. A differential response pattern was observed by the skill level for testosterone. The low skill group displayed a significant increase in testosterone with game play (mean 6 SD, testosterone PRE: 418.3 6 89.5 pmol•L 21 , POST: 527.6 6 132.4 pmol•L 21 , p , 0.001), whereas no change was observed in the high skill group. There were no differences in heart rate characteristics between skill groups. Overall, the average heart rate was 107.2 6 17.8 bpm with an average max heart rate of 133.3 6 19.1 bpm. This study provides unique physiological evidence that a sedentary Overwatch match modulates endocrine and cardiovascular responses, with the skill level emerging as a potential modulator.

Examining Physiological Changes during Counter-Strike: Global Offensive (CS:GO) Performance in Recreational Male Esports Players

“…The authors also noted the different hormonal response patterns of the tournament participants and stratified them into subgroups according to the observed direction of change in cortisol levels. One of the few studies conducted in the field of esports physiology concerns the relationships between a player's skill level and the hormonal and cardiovascular responses recorded during a match [20]. The authors did not observe differences in cortisol levels between athletes with high and low skills.…”

The Sleep, Anxiety, Mood, and Cognitive Performance of Oceanic Rocket League Esports Athletes Competing in a Multiday Regional Event

“…A key strength of the present study is that the sample comprised professional esports athletes competing in a Tier 1 league (i.e., Rocket League Championship Series, Season 11) within an established international esports title. Many studies within the esports literature use easier to recruit samples, such as high school (e.g., Moen et al, 2022) and college students (e.g., Kraemer et al, 2022) or high-ranked nonprofessionals (e.g., Poulus et al, 2020), who are less elite and compete within a very different competitive environment compared with professionals. However, the trade-off for recruiting professional esports athletes is that the sample size is smaller.…”

Stressors and Coping Strategies in Esports: A Systematic Review

“…Leis and Lautenbach (2020) provided an overview of empirical evidence on stress responses in esports, highlighting mixed results on psychophysiological stress related to competitive esports gameplay. Following the authors' call for more research on psychological and physiological stress in esports, studies have demonstrated endocrine and cardiovascular responses during competitive gameplay (e.g., Kraemer et al, 2022;Mendoza et al, 2021). Although research on esports players' experiences (e.g., stressors) and behaviors in esports (e.g., coping) has been increasing over recent years (e.g., Leis et al, 2022;Poulus et al, 2022b;Smith et al, 2019), no study comprehensively addressed research on stressors and coping in esports.…”
