本研究旨在探討中華大學學生個人背景變項和運動參與行為(運動頻率、運動持續時間)在健身運動自我呈現、社會體型焦慮與BMI的差異情形;及健身運動自我呈現、社會體型焦慮、運動行為和BMI(Body Mass Index, BMI)的相關情形。參與者共1435位(男生874、女生561位),平均年齡為20.17±1.59歲,平均身高為168±8.65公分,平均體重為62.41±14.06公斤,平均身體質量指數(BMI)為21.99±3.89。根據研究目的,本研究以獨立樣本t考驗、單因子變異數分析及積差相關進行資料分析,結果發現在健身自我呈現方面:男生在自我呈現動機高於女生、在自我呈現建構方面也高於女生;在社會體型焦慮方面:男生在體形呈現自在高於女生,女生在負面體型評價不安高於男生。不同主觀體重知覺在健身運動自我呈現的差異比較:知覺體重正常組在自我呈現動機和自我呈現建構皆高於知覺體重過重組。社會體型焦慮差異方面:體型呈現自在,體重正常組高於體重過組;負面體型呈現不安,體型過重組高於體型正常組和體型過輕組。不同客觀體重參與者在體形呈現自在上的差異方面:BMI過輕組體形呈現自在的得分高於BMI正常組和BMI過重組、BMI正常組高於BMI過重組。在體形呈現不安上的差異方面:BMI過重組的得分高於BMI正常組和BMI過輕組。運動頻率較高者在自我呈現動機和自我呈現建構上的得分較高。運動時間較長者在自我呈現動機和建構上的得分也較高。在各變項之間相關分析得知:自我呈現動機與自我呈現建構、體形呈現自在、運動頻率和運動時間有正相關存在。自我呈現建構與體形呈現自在、負面體型評價不安和運動時間、頻率有正相關存在。體形呈現自在與負面體型評價不安和BMI有負相關存在,與運動頻率、時間有正相關存在。負面體型評價不安與運動頻率、時間有負相關存在。BMI與運動時間、頻率有正相關存在。
The purpose of this study is to investigate self presentation in exercise, social physique anxiety and BMI in college students' background variation (gender, object and subject perception of body weight) and exercise participating behavior. (exercise frequency, exercise duration) As to the correlations among self-presentation in exercise, social physique anxiety and BMI(Body Mass Index). A total of 1435 participants (male874, female561) mean age 20.17 ± 1.59years old, mean high 168±8.65cm, mean body weight 62.41±14.06kg, mean BMI 21.99±3.89. Data analysis by T-test independent, one-way ANOVA and Persons product-moment correlation. The result revealed that. in selfpresentation in exercise: male had higher in score of self presentation motive and self presentation construction than female did, in social physique anxiety, male were higher in physique presentation comfort and female were higher in negative physique evaluation. In different subject perception of body weight participant in Self-presentation in exercise: normal perception of body weight group was higher than over weight group in self presentation motive and self presentation construction. In social physique anxiety: normal weight group was higher than over weight group in physique presentation comfort and over weight group was higher than normal weight group and under weight group in negative physique evaluation. The difference of different object perception of body weight participant in physique presentation comfort: BMI categorized as under weight group got higher score in physique presentation comfort than that of normal group and BMI normal group higher than over weight group. In physique presentation uncomfort: BMI overweight group was higher than normal group and under weight group. High exercise frequency participants had higher score in self presentation motive and self presentation construction. Long exercise duration time participants got higher score in self presentation motive and self presentation construction. By correlation analysis between each variation, there were positive correlation in self presentation motive, self presentation construction, physique presentation comfort, exercise frequency and exercise duration time. Also positive correlation revealed in self presentation construction, physique presentation comfort, negative physique evaluation, exercise frequency and exercise duration time. Physique presentation comfort group was negative correlation with negative physique evaluation, BMI and positive correlation with exercise frequency, exercise duration time. Negative physique evaluation was negative correlation with exercise frequency and exercise duration time. BMI, exercise frequency and exercise duration time were positive correlation.
