Özet
This study examined the effects of an 8-week PETTLEP-assisted biofeedback (BFB) training program on physiological parameters, cognitive performance, and serve accuracy in female volleyball players. Fourteen athletes were randomly assigned to an experimental group (EG) and a control group (CG). The EG underwent an 8-week PETTLEP-assisted BFB training. Participants completed pre-and post-training physiological (e.g., Nexus 10 BFB device), cognitive (e.g., Stroop test), and overhand serve accuracy assessments. Results showed a positive effect of the training on skin temperature, frontalis muscle activity, Stroop effect, and serve accuracy in the EG from pre-to post training. Moreover, significant between-group differences were observed in skin temperature and service accuracy after training. These results suggest that PETTLEP-assisted BFB training is a promising tool for fostering physiological, cognitive, and sport-specific improvement in female volleyball players. Future studies should recruit athletes from other sports disciplines to generalize the results to other athletic populations.
