In October 2022, eligible E-athletes were openly recruited for the e-sports major at Shandong Sport University. Shandong Institute of Sports, the first higher education institution in China to offer an eSports undergraduate program, has high-quality E-athletes who are strictly different from ordinary healthy people. All subjects were E-athletes who had participated in relevant eSports tournaments and had previous extensive eSports real-world experience. The inclusion criteria are as follows:Good physical health with no history of illness or family diseases;Playing time exceeding 14 hours per week for 6 months;Voluntary participation in the study and ability to complete training according to the requirements;Right-handed.The exclusion criteria are as follows:Severe injury or unrecovered sports injury history;Recent taken any drugs that have exciting or paralyzing effects on nerves;Participation in similar experimental projects within 3 months;Unwillingness to participate in the study;Red-green color blindness.Sample size estimation was conducted based on the results of the pre-experiment regarding the Sequence memory test, Chimp test, Aim trainer test, Visual memory, and Reaction time. Sequence memory test (points): Experimental group (pre = 8.25 ± 1.50, post = 11.25 ± 0.96), control group (pre = 8.25 ± 1.26, post = 9.00 ± 1.41). Chimp test (points): Experimental group (pre = 8.00 ± 2.16, post = 10.50 ± 1.00), control group (pre = 8.50 ± 1.29, post = 8.75 ± 0.96). Aim trainer test (ms): Experimental group (pre = 614.75 ± 41.99, post = 484.75 ± 39.54), control group (pre = 548.50 ± 42.63, post = 531.25 ± 39.69). Visual memory (points): Experimental group (pre = 9.75 ± 0.96, post = 12.00 ± 0.82), control group (pre = 10.50 ± 1.73, post = 11.50 ± 1.39). Reaction time (ms): Experimental group (pre = 252.00 ± 39.27, post = 231.75 ± 30.36), control group (pre = 243.00 ± 17.61, post = 238.00 ± 12.83). After conducting a repeated measures analysis of variance, the effect sizes were found to be ηThe 34 participants were randomly divided into 2 groups of 17 people each. The randomization method is the random number table method, which uses a computer to generate a random number table containing 50 natural numbers in 10 rows and 10 columns, all randomized horizontally, vertically, or diagonally. First, 34 consecutive digits of a particular section were random selected from the random number table. Then the 34 subjects were numbered in the order of group entry and arranged in the order corresponding to the random numbers, specifying that those with odd corresponding random numbers entered Group 1 and those with even corresponding random numbers entered Group 2. Complete randomization of the groups can be achieved with this method.This study was conducted by the Helsinki Declaration and was approved by the Ethics Committee of Sports Science (approval number: 2022007). The responsible person informed the participants of the study content and procedures verbally and in writing. All participants were given written informed consent before voluntary participation in the study and signed a paper consent form. Participants were free to withdraw from the study without further consequences.
