Standing Balance Control: Physical Characteristics and KAT 2000
摘要
INTRO: Balance is defined as a state of bodily equilibrium or the ability to maintain the center of body mass over the base of support without falling. Balance is important for physical activities, especially for athlete's excellent performance and serious sports competition. Inefficient or poor balance abilities will result in poor athletic performance and frequently sports injuries. Additionally, the risk of injury or reinjury may be increased if the athlete cannot maintain proper balance control during practice or competition. The balance can be classified as two parts: static equilibrium, standing without any motion, and dynamic equilibrium, movement in stable locus without any perturbation. Previously studies focused more on the effects of injury on ankle position and balance control, others examined the influences of exercise training, rehabilitation and specific exercise involved on balance ability. The purpose of this study was to examine the relationship between physical characteristics and standing balance control.METHORD: 28 physical active college male students, randomly assigned and counter balance to undertake the following tests: 1. Physical measurement, 2. Standing balance test (KAT 2000), 3. Ankle inversion/eversion isokinetic test. This experimental designed to eliminate the sequence, fatigue and learning effects on test procedures and less bias on data measurement. AII data were expressed as Mean±SD and analyzed with descriptive statistics and Pearson correlation coefficient.RESULTS: Results showed that positive correlation between height, weight, leg length and knee-ankle length(r= .41~.85, p＜.05), and positive correlation with ankle inversion and eversion peak torque in each leg(r= .43~.73, p＜.05). On the other hand, all the physical characteristics and ankle inversion/eversion strength were rarely correlated with KAT 2000 balance performance(r= -.32~.34, p＞.05). The KAT 2000 balance performance in each condition were Left Static (1 82.58) better than Right Static (233.40), Bilateral Static (255.30) and Bilateral Dynamic (980.73). The result also showed that the unpredominant leg have better standing balance control than predominant leg.CONCLUSION: There were no significant correlations between physical characteristic and standing balance control. The ankle inversion and eversion strength (30°/s) were unable to predict the performance of balance control. However, the reliability of KAT 2000 should be taking into consideration. Further research should use more precise and accurate equipment, and recruit different and particular subjects. Furthermore, identify balance control related muscles and examine its influence and effect also need to be clarified.
