The purpose of this study was to determine the effect of a combination of aerobic exercise and hypocaloric diet on body composition, cardiovascular function and some cardiovascular risk factors in obese patients. Ten subjects, (8 women 2 men X age 30 years and 138% of ideal body weight) volunteered as participants. The program lasted 12 weeks and consisted of a hypocaloric diet (1257 kcal/day) and 3-5 days/week supervised sessions of aerobic exercise (65-90% maximal heart rate and/or 50-80% of maximal oxygen uptake). The program resulted in a significant mean decrease in body weight of 7.7 kg. for the group (P less than or equal to 0.05). Mean (+/- EE) relative body fat significantly decreased from 35.9 +/- 2 to 31.6 +/- 2%. Interestingly, the decrease in relative body fat was solely accounted for by a significant decrease in fat weight, as body free of fat remained constant. Cardiovascular function as evidenced by oxygen uptake, increased 11.3%. Resting systolic and diastolic blood pressure fell significantly from 131/90 +/- 8/9 to 115/76 +/- 2/1 mmHg. Total cholesterol significantly dropped from a mean value of 247 +/- 24 to 183 +/- 20 mg/100 ml (P less than 0.05). Triglycerides significantly decreased from 212 +/- 32 to 45 +/- 10 mg/100 ml (P less than 0.05). It was concluded that a combination of aerobic exercise and hypocaloric diet can favorably improve body composition, cardiovascular function and cardiovascular risk factors.
本研究的目的是确定有氧运动和低热量饮食相结合对肥胖患者身体成分、心血管功能及一些心血管危险因素的影响。十名受试者（8名女性，2名男性，平均年龄30岁，体重为理想体重的138%）自愿参与。该项目持续12周，包括低热量饮食（1257千卡/天）和每周3至5天的有氧运动监督课程（最大心率的65 - 90%和/或最大摄氧量的50 - 80%）。该项目使该组的平均体重显著下降了7.7千克（P≤0.05）。平均（±标准误）相对体脂从35.9±2%显著降至31.6±2%。有趣的是，相对体脂的下降完全是由于脂肪重量的显著减少，因为去脂体重保持不变。以摄氧量为指标的心血管功能提高了11.3%。静息收缩压和舒张压从131/90±8/9显著降至115/76±2/1毫米汞柱。总胆固醇从平均值247±24显著降至183±20毫克/100毫升（P＜0.05）。甘油三酯从212±32显著降至45±10毫克/100毫升（P＜0.05）。研究得出结论，有氧运动和低热量饮食相结合可有效改善身体成分、心血管功能及心血管危险因素。
