近年來3C 產品的普及和社群軟體(如Facebook、Line 和Twitter 等)的興起，大學生的生活習慣受這些 因素的影響，身體機能也因此產生了變化，而這些改變也間接導致心肺功能的慢性疾病。本研究以元培大 學某科系42 位同學為實驗對象，分別對其進行性別、身高、身體質量指數(Body mass index: BMI)、骨骼肌 率(Skeletal muscle rate: SMR)、及基礎代謝率(Basal metabolic rate: BMR)的紀錄，而肺功能的分析則透過肺 計量器(Spirometer)分析受測者的肺活量(VC)、用力肺活量(FVC) 、第一秒用力呼氣容積(FEV1)等三項肺功 能指標。實驗數據以IBM SPSS 22.0 統計分析軟體，分別進行獨立樣本T 檢定或單向ANOVA 檢定，來分 析各組別間的平均數是否具有顯著性的意義，結果顯示BMI、SMR 及BMR 對於肺功能指數的影響都具有 顯著性的差異。研究數據指出：(1) BMI 偏低組(<20)，肺功能指數VC、FVC 與FEV1 較正常組與偏高組來 的差，其平均值差異皆有顯著上的意義(p 值皆<0.001)；(2)在骨骼肌率與肺功能的分析數據中，我們卻發現 FVC、VC 與FEV1，與骨骼肌率是呈現顯著的負相關，代表骨骼肌率越高的學生其肺功能指數反而是較低 的；(3)在基礎代謝率與肺功能指數的分析結果顯示，較高基礎代謝率比起較低代謝率的學生，不管是FVC、 VC 或FEV1 都有較好的表現。

In recent years, the popularity of 3C products, and community media (such as Facebook, Line, Twitter, etc.), the physical function of college students affected by these factors, and these changes also indirectly lead to chronic heart and pulmonary diseases. In this study, 42 students of Yuanpei University of Medical Technology were enrolled as experimental subjects; their gender, height, BMI (Body mass index), SMR (Skeletal muscle rate), and BMR (Basal metabolic rate) were recorded. The pulmonary functions’ indices (include vital capacity: VC, forced expiratory volume in one second: FEV1 and forced vital capacity: FVC) of subjects were measured by the Spirometer machine. Data were analyzed using IBM SPSS statistical software 22.0. ANOVA and independent samples T test were used to compare the means of two or three different samples. Results showed that there had statistically significant difference between BMI, SMR, BMR and pulmonary function indices. Research data indicated that: (1) BMI lower group (<20), lung function indices VC, FVC and FEV higher than the normal group and the difference between the groups, all the means difference had significant meaning (all p value <0.001); (2) from the analyzed data of pulmonary function and SMR, we found FVC, VC and FEV1, to SMR were showing significant negative correlation, the higher SMR group of students whose pulmonary function indices were lower than other groups; (3) the analysis results in basal metabolic rate and pulmonary function indices showed higher basal metabolic rate groups had better performance on FVC, VC or FEV1.
