The aim of this investigation was to analyze differences in body composition and body fat distribution between subjects following a structured cardiac rehabilitation program (CRP) and subjects not involved in any CRP.
Body composition and body fat distribution were assessed by dual-energy X-ray absorptiometry (DXA) in 62 male subjects, white, who had been diagnosed with coronary artery disease (CAD). The sample came from two groups: a CRP group (n=31) who had been engaged in phase IV of a CRP for more than a year (age: 58 +/- 10 years), and a non-CRP group (n=31) who were not involved in any CRP (age: 59 +/- 12 years).
The non-CRP group showed higher values than the CRP group in the following variables: body weight (84.924 +/- 11.250 kg vs. 79.077 +/- 10.050 kg, p < 0.05), BMI (29.0 +/- 3.2 kg/m2 vs. 27.3 +/- 2.6 kg/m2, p < 0.05), body fat (BF) (24.584 +/- 6.696 kg vs. 20.010 +/- 7.340 kg, p < 0.05), % BF (28.6 +/- 4.9% vs. 24.7 +/- 6.7%, p < 0.05), trunk BF (14.563 +/- 4.408 kg vs. 11.430 +/- 4.743 kg, p < 0.01), % trunk BF (32.8 +/- 6.0% vs. 27.4 +/- 8.5%, p < 0.01), abdominal BF (2.934 +/- 1.068 kg vs. 2.083 +/- 1.058 kg, p < 0.01), % abdominal BF (37.2 +/- 6.1% vs. 31.3 +/- 9.4%, p < 0.01), visceral BF (2.401 +/- 0.693 kg vs. 1.731 +/- 0.826 kg, p < 0.01), % visceral BF (35.5 +/- 5.7% vs. 29.6 +/- 9.1%, p < 0.01), abdominal subcutaneous BF (0.533 +/- 0.421 kg vs. 0.353 +/- 0.257 kg, p = 0.05) and abdominal BF/BF ratio (0.12 +/- 0.03 vs. 0.10 +/- 0.02, p < 0.05). There were no significant differences in the other variables studied, including total and regional fat-free mass.
These results show that the subjects who did not participate in any CRP had a more adverse profile of body composition and body fat distribution. The higher values found for specific fat depots, as well as for the total abdominal BF/BF ratio, confirm the more adverse body fat distribution in non-CRP subjects. These data are in agreement with results from intervention studies in CAD patients.
本研究旨在分析接受结构化心脏康复计划（CRP）的受试者与未参与任何CRP的受试者在身体成分和体脂分布方面的差异。
采用双能X线吸收法（DXA）对62名被诊断患有冠状动脉疾病（CAD）的白人男性受试者的身体成分和体脂分布进行评估。样本来自两组：CRP组（n = 31），他们已参加CRP第四阶段超过一年（年龄：58±10岁）；非CRP组（n = 31），他们未参与任何CRP（年龄：59±12岁）。
在以下变量中，非CRP组的值高于CRP组：体重（84.924±11.250千克对79.077±10.050千克，p<0.05）、体重指数（BMI）（29.0±3.2千克/平方米对27.3±2.6千克/平方米，p<0.05）、体脂（BF）（24.584±6.696千克对20.010±7.340千克，p<0.05）、BF百分比（28.6±4.9%对24.7±6.7%，p<0.05）、躯干BF（14.563±4.408千克对11.430±4.743千克，p<0.01）、躯干BF百分比（32.8±6.0%对27.4±8.5%，p<0.01）、腹部BF（2.934±1.068千克对2.083±1.058千克，p<0.01）、腹部BF百分比（37.2±6.1%对31.3±9.4%，p<0.01）、内脏BF（2.401±0.693千克对1.731±0.826千克，p<0.01）、内脏BF百分比（35.5±5.7%对29.6±9.1%，p<0.01）、腹部皮下BF（0.533±0.421千克对0.353±0.257千克，p = 0.05）以及腹部BF/BF比率（0.12±0.03对0.10±0.02，p<0.05）。在其他研究变量中，包括全身和局部去脂体重，均无显著差异。
这些结果表明，未参与任何CRP的受试者在身体成分和体脂分布方面具有更不利的特征。特定脂肪储存部位以及腹部BF/BF总比率的较高值证实了非CRP受试者的体脂分布更不利。这些数据与CAD患者干预研究的结果一致。
