摘要：International Journal of Exercise Science 10(8): 1105-1115, 2017. Biofeedback is a method of controlling normally automatic bodily functions by monitoring and training to acquire voluntary control over them (13). The purpose of this study was to determine if a heart-rate variability training program utilizing the emWave biofeedback device could increase performance on a simple strength task. Participants (n = 18) were randomly assigned to one of three groups and data were collected for a period of seven weeks. Data collection consisted of participants receiving training (experimental and alternate groups) or no training (control group), followed by a chest press one repetition maximum (1-RM) assessment. A repeated measures ANOVA was conducted to assess group differences in chest press 1-RM improvement over time. While all three groups improved in chest press 1-RM over time, there were no significant differences between groups. Future directions and implications of this research for athletes and coaches are discussed.
