本研究主要是探討運動介入後學生身體質量指數(Body Mass Index, BMI)變化及其主要之影響因素。以35位國中二年級體重控制班學生為樣本,實施身高、體重之前測並填寫問卷後,給予15週之運動介入,後測其BMI值,由問卷中之個人因素與社會因素變項,以統計分析其運動介入前後之BMI數值之影響因素及相關性。由研究結果得知,運動介入,對研究對象之BMI數值有下降之改善,其中體重控制的行為信念及態度愈強及內控型人格兩因素對BMI數值的下降有顯著的影響。而父母對其體型的負向評價及對體重控制的忠告與支持愈高者,對其BMI數值之下降則較少。
The purpose of this study is to explore the Body Mass Index (BMI) variation and influential factors of exercise intervention on 35 second-grade junior high students. And in additions, they were enrolled to follow the body weight regulation program. Before exercise intervention of 15 weeks, they were offered the measurement of height and weight and a questionnaire. After weekly exercise intervention, it is necessary to record and calculate the BMI variation. The study uses items of questionnaire (individual factors and social factors) to analyze the difference between and the relation of BMI variation after each exercise intervention. With the outcome of the study, it can be found that there is a relation between the BMI variation of samplings and scores of total questionnaire scale. The stronger the behavioral beliefs and attitudes of body weight controlled is, the more obvious influence that the internal-controlled personality affects the value of BMI will be Besides, when parents give more negative criticism, higher degree of taunts, and more advice and support, the less the BMI variation will go down.
