Quiet eye training (QET) is a psychological skill training method aimed at improving skill learning and coping with stress by prolonging the duration of quiet eye fixation. Despite a growing empirical evidence base for QET in academic literature, a systematic review of its effectiveness is lacking. Therefore, this paper focuses on the key issue of whether QET can be used as an effective training means to improve sports performance and systematically summarizes and analyzes the related research on the intervention of sports performance through QET. The aim is to explore the underlying physiological mechanisms of QET and assess its practical intervention effects, thereby informing sports training practices. In this study, we conducted a systematic search across several authoritative databases, including CNKI, PubMed, Web of Science, ScienceDirect, and Google Scholar, up to October 31, 2024. Given the unique characteristics of each database, a corresponding Boolean logic search formula was customized. Eligible documents were identified based on predefined inclusion and exclusion criteria. Then, the quality of the included documents will be evaluated PEDro quality evaluation screening scoring system. Finally, structured data was extracted in accordance with the PICOS principle. After searching and screening, 10 articles were selected for final analysis. Participants involved in the study include athletes, college students, and children of different ages and backgrounds, ranging from 8 to 24.5 years old. The research focuses on two main types of intervention: quiet eye training (QET) and technical training (TT). QET aimed to enhance performance by extending fixation duration and synchronizing vision with motor actions, whereas TT emphasized motor technique aspects. Intervention durations varied from two to eight weeks. The research results generally show that QET, as an intervention method, can effectively improve athletes' performance. Athletes subjected to quiet eye interventions exhibited longer quiet eye (QE) durations and superior sports performance compared to those in control conditions. A positive correlation was observed between the enhancement of QE duration and the outcome of sports performance. The implementation of quiet eye interventions accounts for variations in athletes' skill levels, as the effectiveness of these interventions varies accordingly. Despite the relatively limited impact of quiet eye training on regulating athletes' anxiety, it remains highly significant in enhancing performance under pressure.
