Competitive video gaming, also known as eSports, is a growing industry in the US and worldwide. As interest in eSports has grown, so has the interest in those who participate, particularly competitive eSports athletes. The physiological and cognitive impact of various training regimes, high frequency and duration of play, and live or virtual competitions has gained recent attention. The aim of this study was to characterize potential cognitive and physiological differences among competitive gamers and non-gamers while accounting for fitness levels. Specifically, the physiological parameters compared were differences in stress response [as measured by changes in heart rate (HR), blood pressure (MAP), and respiration rate (RR)] due to cognitive load (via various cognitive assessments) and fitness measurements such as body composition and health and skill related fitness components. Twenty-two total participants were studied [n=11 in gamers (9M, 2F, play gt;5 hrs/wk) and non-gamers (8M, 3F)]. The six different cognitive tests used were to measure various neurocognitive components that have previously been shown to be enhanced in gamers: the Stroop Test (cognitive set shifting, inhibitory control, and set twitching), Modified Card Sorting Test (problem solving and abstract thinking), Finger Tapping Test (psychomotor speed), Trail Making Test (speeded visual search and tracking), Spatial Processing Task (spatial recognition), and Iowa Gambling Test (risky decision making) were administered via a computer (Millisecond).  After completing cognitive testing, each subject’s health-related fitness components (muscular strength and endurance, flexibility, and estimated aerobic capacity) were assessed with a handgrip dynamometer, Situp Bleep test, V Sit and Reach Test, and Modified Bruce Treadmill, respectively. Skill-related fitness components (power, balance, hand-eye coordination) were assessed with vertical jump, the Balance Error Scoring System, and the Alternate Hand Wall Ball Test, respectively. Body anthropometrics was measured through height, weight, BMI, body fat percentage (via bioelectrical impedance analysis), and hip-to-waist measurements. Of the cognitive components assessed, the only difference was that the video gamers had average scores for the Finger Tapping Test (70.1±10.6) that were trending towards significance versus the non-gamers (62.3±6.7; p=0.052). The systemic physiological responses to the cognitive testing were minimal (non-gamers: ∆MAP -1.7 to 0.3 mmHg, ∆RR 0.1 to 3.4 BPM, ∆HR -3.5 to 7.8 BPM; gamers: ∆MAP -0.01 to 1.5 mmHg, ∆RR 2.4 to 4.3 BPM, ∆HR -2.7 to 4.0 BPM) and did not differ between the two groups. As intended, given the potential impact of fitness on cognitive performance and sympathoexcitation, the fitness levels of the participants were not different. Thus, when physical activity is accounted for, competitive gamers and non-gamers perform similarly in most cognitive tasks and have similar physiological responses to this stress.
