竞技体育涉及生理,技术和心理技能,这直接影响了个人的表现。这项研究旨在调查在职业电子竞技运动员的胜利和失败之前和之后的感知压力和心率变异性(HRV)水平。我们的假设是获胜者在比赛后会有更好的自主神经和应激反应,从而证实了有关神经心脏连接的文献。从10个不同的巴西队中选出了50名男性电子竞技球员。实验分2个阶段进行。首先,签署知情同意书后,比赛前24小时,人体测量学,仅记录身体活动水平和专业知识时间数据以进行样本表征,参与者熟悉感知压力量表-10(PSS-10)和HRV测量.其次,玩家在比赛开始前60分钟和30分钟休息时进行了PSS-10和HRV记录(即,基线时间)和游戏结束后10分钟。总的来说,关于PSS-10,我们的研究结果表明,与基线(BL)和赛前时间相比,VG在赛后时间的得分显着降低,与BL和赛前时间相比,DG在赛后时间的得分显着增加。关于HRV,我们的结果表明,VG的RR显着增加,SDNN,rMSSD,pNN50和HF,LF和LF/HF显著下降,而DG的RR显著下降,SDNN,rMSSD和HF,LF和LF/HF显著增加。据观察,VG有更好的HRV反应(更大的副交感神经激活)以及较低水平的感知压力,而DG具有最差的HRV反应(更大的交感神经激活)和更高水平的感知压力。
Competitive sports involve physiological, technical and psychological skills, which influence directly on individuals\' performance. This study aims to investigate the levels of perceived stress and Heart Rate Variability (HRV) before and after matches with
victory and defeat in professional eSports athletes. Our hypothesis was that the winners would have better autonomic and stress responses after match, thus corroborating the literature on neurocardiac connections. Fifty male eSport players were selected players from 10 different Brazilian teams. The experiment was carried out in 2 sessions. Firstly, after signing the informed consent form, 24 h before the game, anthropometric, physical activity levels and time of expertise data were recorded only for sample characterization and the players were familiarized with the perceived stress scale-10 (PSS-10) and the HRV measurements. Secondly, players performed the PSS-10 and HRV recording at rest by 10 min 60 and 30 min before the game (i.e., baseline time) and 10 min after the end of the game. Overall, concerning PSS-10 our findings show that VG had significant reduced scores in post-game time compared to baseline (BL) and pre-game times, while DG had significant increased scores in post-game time compared to BL and pre-game times. Regarding HRV, our results demonstrate that VG had significant increase in RR, SDNN, rMSSD, pNN50 and HF, and significant decrease in LF and LF/HF, while DG had a significant decrease in RR, SDNN, rMSSD and HF, and significant increase in LF and LF/HF. It was observed that VG had better HRV responses (greater parasympathetic activation) as well as lower levels of perceived stress, while DG had worst HRV responses (greater sympathetic activation) and higher levels of perceived stress.
