Balance and Muscular Strength in Normal Children Aged 9-12 years
9到12歲正常兒童的平衡與肌力之相關研究
摘要
本研究的目的為，第一、分析數項獨立自變數對平衡能力及肌肉力量(動態肌力及靜態肌力)的影響情況；第二、了解在本實驗中所測得之平衡能力及兩項肌力間之相關情況。本實驗的研究對象為99位健康正常的兒童，男孩有58位，女孩41位，年齡由9.6歲至12.7歲。此99位受測對象為高雄市一所國民小學中之第4，5，6年級的班級中，經隨意選出的學童。研究步驟為，在平衡能力測量方面，使用Bruininks Oseretsky test of Motor Proficiency (BOTMP)中之第二次測驗，此次項測驗特別為測量平衡能力所設計，其中共有8項施測細目。此外，使用BOTMP中之第四次測驗以測量動態肌肉力量。在靜態肌力測量方面，本實驗使用Force Evaluation and Testing System(FET)，以半蹲雙手提拉姿勢下取得量化的靜態肌力數值。並記錄每位兒童的身高及體重。用逐步迴歸統計法分析各項獨立自變數分別對平衡及兩項肌肉力量的影響情況。結果顯示體重及動態肌力為估計平衡分數之有效預測因子；靜態肌力之有效預測因子為性別及體重，而在預測動態肌力分數中，得知性別、體重、身高及平衡分數此四因子為有效預測因子。斯皮爾曼(Spearman)相關係數分系結果顯示平衡分數與動態肌力分數具有統計學上明顯正相關，動態肌力分數與靜態肌力間也有明顯之正相關，而平衡分數與靜態肌力間為顯著的負相關。其中詳細的分析載於文章的討論部份。

The purposes of this study were two fold. The first was to determine the effects of several independent variables onf balance, and also on two muscular strength (dynamic and static) measurements respectively. The second purpose was to examine the trlationship among the balance and the muscular strengths. Ninety-nine healthy children (58 boys and 41girls) ranging in age from 9.6 to 12.7 years participated in this study. The subjects were selected from the 4th, 5th and 6th grades of an elementary school in Kaohsiung City. To assess balance, children were administered subtest 2 of Bruininks Oseretsky test of Motor Proficiency (BOTMP). Dynamic strength was measured with the subtes 4 of the BOTMP. Static strength was measured quantitatively by “semi-squat two-hand lift”. The Force Evaluation and Testing System was used for this testing. Hight and weight measurements were obtained on each subject. The independent effects of variables on balance score and the two muscular strengths were assessed by stepwise multiple-regression analysis. The results revealed weight and dynamic strength were the effective predicors on estimation balance score. Gender and weight were found as important variables contributing in static load, whereas gender, weight, heihgt and balance score were selected for significantly predicting dynamic strength scroe. Spearman correlation analysis revealed significant positive correlations between balance and dynamic strength and also between dynamic strength and static strength. The correlation analysis also showed a significant negativecorrelation between balance and static strength. Detailed implications of the results in the present study are discussed.
