中文摘要 | 肥胖與許多健康上的危險因素關係密切。本研究目的是要探討肥胖患者與正常體重的人在踏車運動時之心肺功能反應的差異。肥胖組有23位女性,其平均年齡為39.6±13.2歲,體重為71.4±7.0kg,而身體質量指數(BMI)為29.0±2.0 kg/m2。對照組則有23位年齡與身高相匹配而體重正常的女性。受試者除了接受一般性體驗外,均以固定式踏車作一次最大運動測驗。在測驗進行時,除了作心電圖監視,並逐次分析其呼出氣體,以記錄受試者換氣量、攝氧量和二氧化碳呼出量等生理變數的變化。結果發現在最大運動時,肥胖組的最大攝氧量較對照組為高(1.7±0.31.min-1 vs 1.4±0.31.min-1)。但是,肥胖組的單位體重最大攝氧量卻較對照組明顯為低(13.6±2.1 ml, kg-1, min-1 vs 15.6±3.8 ml,kg-1, min-1)。至於最大換氣量與最大心博率,兩組則無明顯差異。在無氧閥值時,肥胖組的單位體重攝氧量也較對照組為低。由上述結果可知肥胖組的攝氧總量雖較對照組為高,但是其單位體重攝氧量卻較對照組為低。此結果可以解釋肥胖體能較差,且其運動耐力偏低的原因 |
英文摘要 | Obesity is a major health problem. There is considerable information regarding the association between excessive body fatness and many health risks. The purpose of this study is to compare the cardiorespiratory responses of female obese subjects and normal-weight women during cycle ergometry. The obese group included 23 female subjects with mean age of 39.6±13.2 years (range: 19-57 yrs.). The mean body weight of obese subjects was 71.4±7.0kg, and the body mass index (BMI) was 29.0±2.0 kg/m2. The control group included 23 normal-weight women with matched age and body height. Breath-by-breath measurement of the cardiorespiratory function was obtained during the incremental exercise of leg cycling. The anaerobic threshold (AT) was determined by ventilatory criteria. In the maximal exercise, the oxygen uptake (VO2max) of the obese group was significantly higher than respective value of the control group (1.7±0.3 1.min-1 vs 1.4±0.3 1.min-1). However, the VO2 max per kilogram of body weight of the obese group was lower than that of the control group (13.6±2.1 ml.kg-1.min-1 vs 15.6±3.8 ml.kg.min-1). The higher absolute oxygen uptake for the obese subjects may partly be attributed to the increase in lean body mass (LBM). At the anaerobic threshold, the obese group also showed lower VO2 per kilogram of body weight. It is concluded that the obese group had lower oxygen uptake per unit of body weight in the maximal exercise as well as at the AT, and this result may explain why obese subjects usually experience exercise intolerance during ordinary activities. |
