The Impact of Heart Rate Variability Biofeedback on Anxiety Reduction and Batting Performance Enhancement in Taiwan University Baseball Players

Abstract: Background: A commonly observed phenomenon is that although the players in a baseball team have received the same raining content and volume, their batting performance is quite different. As no optimal solution exists for this problem at present, this study attempted to explore the potential of heart rate availability biofeedback (HRVB) to reduce anxiety and improve batting performance in university baseball players. Materials and Methods: A total of 18 college baseball players were randomly divided into an experimental group and a control group. Both groups answered questionnaires and had their physiological signals and batting performance measured on the first and last days of the experiment (i.e., days 0 and 10, respectively). Only the experimental group received HRVB training between the first and last days (10 days in total). Results: There sultsshowed hat before training, no significant differences were found in physiological, psychological, or performance parameters between the two groups. Compared to the control group, following HRVB training, the experimental group showed a notable decrease in cognitive anxiety (before HRVB: 23.56 ± 4.07; after HRVB: 20.11 ± 4.78; p < 0.05) and their batting performance improved significantly (batting score increased from 9.8 ± 11.7 to 19.8 ± 12.0 after HRVB; p < 0.05). Conclusions: This study validated that the use of HRVB can help to improve batting performance and reduce anxiety in college baseball players. Therefore, HRVBcanbeapplied before competition matches, helping the players to perform better.
