INTRODUCTION:
The aim of this study is to summarize and summarize the application of biofeedback in the field of sports, and give some suggestions on its future research trends. Biofeedback is developed by combining multi-disciplinary research. At the end of 1970s, biofeedback technology was widely used in the sports field. Up to now, the research of biofeedback training in the field of sports focuses on the field of sports psychology and sports rehabilitation, it is widely used because of its non-invasive and convenient operation.
METHODS:
It was a narrative review study. We used the following keywords to search the Web of Science、EBSCO Academic search Complete database: ‘sports’ and ‘biofeedback’ to qualify articles to analysis.We searched for reports published between 2000 and 2023. Two independent researchers completed the procedure between July 2023 and November 2023.?In the first step, we obtained 39 studies .The studies had to meet the following requirements: (a) published scien-tific articles; (b) experimental or quasi-experimental reports; (c) use of biofeedback as the main treatment.A total of 14 articles were included in the study, and the following criteria were analyzed: sports events, biofeedback methods, evaluation indicators, application effects.
RESULTS:
The results of 92% (N = 13) showed that biofeedback training had a positive effect on the improvement of athletes ability. It can not only reduce athletes pre-competition anxiety, regulate the level of arousal, improve the athletes ability of emotion regulation and self-control, but also improve the learning efficiency of sports skills, also can enhance the human body muscle strength and balance function, prevent sports injury, improve sports performance. Only 8% (N = 1) of the results were negative, which may be related to the sports program and sociological factors.
CONCLUSION:
The results show that most of the biofeedback training plays a positive role in improving sports ability, which proves that the biofeedback training is practical and scientific, and is an effective way to improve the training effect of sports ability. However, The ecological validity of biofeedback training is a problem worth paying attention to, that is, whether the biofeedback training effect can be transferred from the laboratory to the real sports training and competition situation. Although some studies have tried to carry on the training in the sports field, but this aspect of the research is limited and needs to be further strengthened.
Athletes of different sports may also benefit from different biofeedback information during training, for example, Judo require strength and a high level of muscle movement, therefore, electromyography and skin current may be better training methods, while shooting and archery require good psychological preparation and high concentration, so choose EEG feedback training is more appropriate. Therefore, the correlation between different biofeedback methods and sports events needs further study.
