Esport players require a high number of action moves per minute to play, with substantial contractions of the wrist extensor muscles. Players frequently suffer from acute fatigue. The purpose of this study was to examine the use of below the elbow compression sleeves on Sm02 during intense aim training. Secondly, to examine players' performance and perception with and without compression.
This study was conducted at the New York Institute of Technology and enrolled fifteen collegiate esport players, 2 women and 13 men (age 21.2 ± 2.2). All subjects signed written consent. Participants performed 3 high intensity bouts of an aim trainer followed by a 15-minute rest before doing another 3 bouts of high intensity training conducting the other arm of the study. The compression wear order was randomized. The primary outcome included Sm02 of the extensor carpi radialis longus using near-infrared spectrometry. Secondary outcomes included Kills Per Second (KPS), Score, Total Time to Kill (TTK), accuracy, and perceived performance.
Following 15 min of recovery, there was a significant rise in Sm02 while wearing the compression sleeve compared to no compression sleeve (p = 0.004). No change in Sm02 was seen while gaming. In trials 1 and 2, wearing the compression sleeve resulted in a significant increase in KPS and score when compared to not wearing it (p = 0.002,0.006). Although TTK and accuracy did not alter, 46.7% of participants believed the compression sleeve aided their performance.
This study provides support that wearing below the elbow upper body compression sleeves while performing high intensity gaming may reduce fatigue, improve muscle recovery and gaming performance.

电子竞技玩家每分钟需要进行大量的动作操作，手腕伸肌会大幅收缩。玩家经常会遭受急性疲劳。本研究的目的是在高强度瞄准训练期间，研究肘部以下压缩袖带对肌肉氧饱和度（Sm02）的影响。其次，研究佩戴和不佩戴压缩袖带时玩家的表现和感受。
本研究在纽约理工学院进行，招募了15名大学电子竞技玩家，其中2名女性和13名男性（年龄21.2±2.2岁）。所有受试者均签署了书面同意书。参与者进行3组高强度的瞄准训练，随后休息15分钟，然后对另一只手臂进行另外3组高强度训练。压缩袖带的佩戴顺序是随机的。主要结果包括使用近红外光谱法测量桡侧腕长伸肌的Sm02。次要结果包括每秒击杀数（KPS）、得分、总击杀时间（TTK）、准确率和主观表现。
恢复15分钟后，与不佩戴压缩袖带相比，佩戴压缩袖带时Sm02显著升高（p = 0.004）。游戏过程中Sm02未见变化。在试验1和试验2中，与不佩戴压缩袖带相比，佩戴压缩袖带时KPS和得分显著增加（p = 0.002，0.006）。尽管TTK和准确率没有改变，但46.7%的参与者认为压缩袖带有助于他们的表现。
本研究支持在进行高强度游戏时佩戴肘部以下的上身压缩袖带可能会减轻疲劳、改善肌肉恢复和游戏表现。
