The Influence Of Bio-feedback Balance Training To Postral Sway On Stable Sustaining Surface Of Common Collage Students

Research value:Balance ability is the ability of keeping posture or making normal body action,and the good balance ability is the essential and basic ability of the daily life and sports.It is beneficial for the accomplishment of quick stable and effective body action to get higher level balance ability and for the decreasing of the probability of the sports injury happening during the body acting.Now the related researches of balance ability are mainly concentrated in the evaluation of body balance ability and the recovering of people who gets disequilibrium,and the researches of balance ability training for the healthy people are so rare.In this years,the appearance of the computer balance evaluating instrument supply the possibility of the evaluating body balance ability by measuring postural sway accurately.To take advantage of this instrument,a noninvasive and interesting bio-feedback balance training can be carry out to improve balance ability.Purpose:The goal of this research is to analyse the changing regular pattern of common collage students static balance ability and this training influence to balance ability by carry out the computer balance instrument bio-feedback training.Methods:30 common collage students were divided to the training group of 15 ones(7males,8females,the average age is 19.76) and control group of 15 ones(7males,8females,the average age is 20.08) randomly.The research method is following:the training group is trained for 4 weeks by the Good Balance instrument,and the 11 indexes of postural sway in 5 postures of the training group and the control group were measured both before and after training to evaluate the training effect.According to analyse the indexes of this research,the following conclusions are gained: 1 According to the clustering analysis and factor analysis of the postural sway indexes,11 indexes are converted to 5 ones,and the evaluating of balance ability are deeply simplified.2 The body balance ability is not only be affected by whether there is the participating of vision system and the size of sustaining surface, but also be imited by the condition of postural.3 The bio-feedback training of this research can effectively improve the balance ability with small sustaining surface or poor condition of muscle traction.The physiology reason of the result needs more animals or body researches to prove.
