摘要

對許多必須背著書包走路上學的學生而言，書包的輕重及背負方式直接影響其舒適及健康。自從小學教科書開放民間編輯後，各版本的課本及習作莫不力求印刷精美、增加插圖，如此一來使得教材重量增加許多，也造成學子們負擔日益沉重，長此以往學童足部受傷的機率將大為升高。足底壓力的變化為臨床上判斷足部病變的重要因素，本研究藉由EMED-pedar足底壓力量測系統測量12名國小男學童（平均年齡11.5±0.52歲、體重40.7±5.7公斤）以了解學童行走速度及負重方式的改變對足底壓力有何影響，受試者背負體重12.5%的書包以105步／分的步頻採取不負重及常見的三種負重方式（右肩負重、左肩右斜、雙肩後背）步行20公尺。將所得資料以相依樣本單因子變異數分析(one-way ANOVA)及事後多重比較(α=.05)。獲得以下結果：1.當行走速度由最適速度（105步／分）變為快速（144步／分）時，最大足底壓力及對地最大作用力將會增加，其中足跟區皆達顯著差異，足中區則未達顯著差異。2.當行走速度由最適速度變為快速時，壓力時間積分值及力量時間積分值則會減少，足前區達顯著差異。3.在最適速度行走時，左、右足足底壓力壓力未達顯著差異。4.快速行走下，採右肩負重及左肩右斜時，其右足足底各分區之最大足底壓力皆顯著大於左足，因此若要使左、右足足底壓力分佈平均，建議學童採雙肩背書包。

The main purpose of this study was to investigate and predict elementary school students' behavioral intention in participating school representative teams. The framework of this study was based on Theory of Planned Behavior by Ajzen (1985). Using stratified cluster sampling method, a group-administrated questionnaire to 500 students living in Taoyuan area was conducted. Out of 500 questionnaires returned, 476 of them were valid. The Alpha coefficients of each subscales is between .74~.89. The collected data was analyzed by Person product-moment correlation and hierarchical multiple regression analysis.
The main findings of this study were: First, most of the students whose intention, attitude, subject norm and perceived behavioral control toward participating school representative team were positive. Second, the relationships among attitude, subject norm, perceived behavioral control were significant positive. Third, the attitude, subjective norm and perceived behavioral control towards participating school representative team could effectively predict participating intention of those students, and the explanation power of variance was 51%. Forth, the results of this study supported the Theory of Planned Behavior is superior to the Theory of Reasoned Action.
