초록
To improve the effect of balance training, visual feedback is usually used. Duringthe training process there are some factors which decrease the effect. Neurophysiologically, the main negative factor is thought to be synaptic fatiguewhich decreases the sensitivity of synapses. The purpose of this study was to fìnda more effective balance training method. In this study, a total of 60 normalsubjects-19-30 years old young males and females(M=30, F=30)- participated, andthey were randomized as A, B, and C group, each group containing 20 subjects. First, all groups had a pre-test of sway balance. One minute later, A group wastrained in sway balance by continuous visual feedback for 2. minutes, B group byintermittent visual feedback which had 4 sessions of 30 seconds each and a oneminute rest break. C group was not trained at all. All groups had a post-test. Only B group had improved balance compared wìth C group by ANOV A. On theother hand, intermittent visual feedback was more effective than continuous visualfeedback in sway balance training with normal subjects. ’
