| This study investigated the efficacy of a biofeedback training program designed to create an optimal pre-performance mind-body state to improve balance beam performance in competition. The aim sought to build upon heart rate variability (HRV) and sensorimotor rhythm (SMR) training done with musicians, baseball players, dancers and surgeons (Egner & Gruzelier, 2001, 2003; Strack, 2003; Raymond et al., 2005; Ros et al., 2009) by extending it to Division 1 artistic gymnasts competing on the balance beam. The training took place over six weeks, beginning two weeks prior to the competition season. Gymnasts (n=11) received a total of ten sessions of SMR and HRV biofeedback training. The study compared scores earned in competition through the duration of the training program to scores earned during the four weeks after the biofeedback training ended. An independent judge blind to the sequence of competitions scored videotaped routines from three points in time: before, mid-way and after biofeedback training. Gymnasts performed significantly better in competition while undergoing biofeedback training compared to after the withdrawal of training, and significantly reduced deductions received on both Artistry and Execution subscales during the course of the biofeedback training. The experience of participants and the improvements seen in scores warrant further research in the use of biofeedback to optimize performance in competition. |
