Abstract

BACKGROUND

Muscular fatigue critically affects health, performance, and safety in daily activities and sports. Esports or competitive gaming involves prolonged sitting and repetitive upper extremity movements, increasing the risk of muscular fatigue. Sustained activity may contribute to long-term musculoskeletal disorders (MSD). Despite this risk, biomechanical analyses in esports remain limited. This study examines muscular fatigue and wrist kinematics in esports athletes across different video game genres.

METHODS

Thirty-two healthy male esports athletes (23.8 ± 3.4 years) participated in two 90-120-minute competitive video gaming sessions, separated by a 10-minute passive sitting break. Surface electromyography (EMG) of the upper trapezius and wrist extensors, as well as wrist kinematics, were recorded. The median frequency (MDF) and root mean square (RMS) were used to quantify muscular fatigue. Statistical analyses included mixed ANOVA, one-way repeated measures ANOVA, and robust ANOVA with Bonferroni correction.

RESULTS

Repeated measures ANOVA indicated significant decreases in the MDF and RMS of the wrist extensors over time (p < 0.001). For the upper trapezius, only the right-side MDF showed a significant decrease over time; however, post-hoc analysis did not confirm this effect. Mixed ANOVA revealed no interaction between time and video game genre on kinematic data. First-person shooter players exhibited significantly greater cumulative distances (p = 0.006) and velocity zero-crossings (p = 0.043) than multiplayer online battle arena players in robust ANOVA.

CONCLUSIONS

The findings indicate a progressive increase in wrist extensor fatigue over time, whereas wrist kinematics vary by video game genre but remain unaffected by time. The lack of neuromuscular recovery post-break suggests the potential for cumulative muscular fatigue. These repetitive loads could increase the risk of MSD. Therefore, implementing preventive training strategies and regular active breaks may help mitigate these effects in esports athletes.

摘要

背景

肌肉疲劳严重影响日常活动和体育运动中的健康、表现及安全。电子竞技或竞争性游戏需要长时间坐着并进行重复性上肢动作，增加了肌肉疲劳的风险。持续的活动可能导致长期的肌肉骨骼疾病（MSD）。尽管存在这种风险，但电子竞技中的生物力学分析仍然有限。本研究考察了不同电子游戏类型的电子竞技运动员的肌肉疲劳和手腕运动学情况。

方法

32名健康男性电子竞技运动员（23.8±3.4岁）参加了两场90 - 120分钟的竞争性电子游戏比赛，中间有10分钟的被动坐姿休息时间。记录了上斜方肌和手腕伸肌的表面肌电图（EMG）以及手腕运动学数据。使用中位频率（MDF）和均方根（RMS）来量化肌肉疲劳。统计分析包括混合方差分析、单因素重复测量方差分析以及采用Bonferroni校正的稳健方差分析。

结果

重复测量方差分析表明，随着时间推移，手腕伸肌的MDF和RMS显著下降（p < 0.001）。对于上斜方肌，只有右侧的MDF随时间显示出显著下降；然而，事后分析并未证实这一效应。混合方差分析显示，时间和电子游戏类型在运动学数据上没有交互作用。在稳健方差分析中，第一人称射击游戏玩家的累积距离（p = 0.006）和速度过零点（p = 0.043）显著大于多人在线战斗竞技场游戏玩家。
